We present the first reported case of histologically proven colorectal adenocarcinoma with metastatic spread to the optic nerve. A 49-year-old man, with a known history of rectal adenocarcinoma, presented with progressive loss of vision in his left eye. On presentation, he had no perception to light in his left eye and Snellen acuity of 6/36 in the right eye. Fundus examination showed a left globally swollen optic nerve with a few flame-shaped haemorrhages. A gadolinium-enhanced MRI scan demonstrated abnormal thickening of the anterior and mid-section of the optic nerve with high signal on STIR and postgadolinium enhancement. Optic nerve biopsy confirmed the presence of epithelial adenocarcinoma compatible with metastasis of gut origin. The patient died within 4 months of presentation.

High Index Of Suspicion

This case presentation examines a rare clinical entity: colorectal adenocarcinoma (CRC) metastasis to the tongue. CRC is among the least common tumors to metastasize to the oral cavity. Objectives for this case report are to (1) maintain a high index of suspicion for oral cavity tumors representing metastatic disease, (2) consider appropriate surgical and adjunctive interventions, and (3) recognize the significance of identifying the primary tumor via immunohistochemical staining. We present a case of a 57-year-old male with a history of stage IV rectal adenocarcinoma metastatic to the lung who presented to our clinic with a painful mass of the right lateral tongue that he noticed one month before. MRI of the neck revealed a mass involving the anterior two-thirds of the right tongue with irregular margins and an ipsilateral enlarged right jugulodigastric lymph node. The patient underwent right partial glossectomy with primary reconstruction and right modified radical neck dissection. Pathology confirmed poorly differentiated adenocarcinoma consistent with a colorectal primary with lymphovascular and perineural invasion. The tumor was staged as T2N1, and the patient was referred for chemoradiation. In this report, we discuss the presentation, diagnosis, and treatment of this uncommon disease, with a thorough review of the world literature.

Extra-adrenal paraganglioma has never been described in the extremities. A 34-year-old woman complained of an enlarging mass in the right forearm for 18 months. Imaging showed a circumscribed vascular tumor attached to the ulnar nerve; biopsy revealed features of paraganglioma. The resected tumor consisted of zellballen pattern of chief cells staining positively for chromogranin with surrounding S100-positive sustentacular cells. The chief cells contained many neurosecretory granules and mitochondria, whereas the sustentacular cells contained a large amount of rough endoplasmic reticulum and some microfilaments. There was adjacent extensive glomus cell hyperplasia and tumorlet formation. The intraoperative blood pressure dropped abruptly on tumor removal. The serum normetanephrine level decreased from a preoperative level of 1987 pg/mL (normal < 149 pg/mL) to normal after operation. The patient admitted on questioning to a history of paroxysmal attacks of transient palpitation, hand tremors, and sweating; imaging showed no evidence of tumor in other parts of the body, and there was no family history of similar tumor; she remained well 33 months after the operation. This occurrence of functional ulnar nerve paraganglioma with the hitherto undescribed associated glomus cell hyperplasia and tumorlet formation attests to the probable existence of normal sympathetic paraganglia in the extremity and their intimate functional relationship with glomus bodies.

Rosai Dorfman disease is a rare histiocytic disorder. It is also known as Sinus Histiocytosis. It is with massive lymphadenopathy involves an overproduction of a type of white blood cell. The disease is rarely associated with intracranial and intraorbital involvement. Intracranial Rosai-Dorfman can mimic meningioma. Other pathologies also underline its pathologies. Here, we report a nine-year-old boy with a history of proptosis of the right eye and presenting with multiple skull lesions. Histopathological study revealed Sphenopetroclival lesion, which features that of Rosai Dorfman Disease. His MRI scan of the brain was taken, which showed evidence of right optic nerve meningioma with sella and suprasellar extension, causing severe proptosis. The child underwent right frontotemporal craniotomy with petrosectomy and Transylvanian, subtemporal approach to multicompartmental Rosai-Dorfmans lesion. After four months, the patient had a recurrence of the disease on which chemotherapy and steroids were started, which also did not show much response while taking an MRI scan. A corticosteroid is a useful option in the Central Nervous System Rosai Dorfman disease treatment. But this patient showed a negative outcome to the treatment.

The majority of cases of orbital emphysema are due to trauma. Complications are rare, and therefore, the need for surgical intervention is uncommon. We present the first case of which we are aware in which nontraumatic orbital emphysema led to orbital compartment syndrome and subsequent optic nerve dysfunction. The patient underwent emergency needle decompression. A 51-year-old man presented to the Emergency Department with right-sided unilateral proptosis, reduced visual acuity, and binocular diplopia. This occurred after performing a Valsalva manoeuvre with no history of head trauma. He also mentioned that over the past year he had experienced multiple episodes of transient proptosis occurring after Valsalva manoeuvres. Visual acuity in the right eye was reduced to 6/21. A relative afferent pupillary defect was present and intraocular pressure (IOP) was 12 mmHg. The CT scan showed significant orbital emphysema in the medial aspect of the right orbit. Needle decompression was performed resulting in immediate resolution of his symptoms. This case demonstrates that, in cases of orbital emphysema, a lack of a history of trauma and a normal IOP cannot always be used to rule out serious pathology.

Abstract OBJECTIVE AND IMPORTANCE: We report the third case of an aneurysm of the lateral sacral artery (AnLSA). In all cases, because of an incorrect preoperative diagnosis, the surgeons were confronted with severe and unexpected hemorrhaging, and surgery was aborted without effective treatment. Our purpose is to present the preoperative features of AnLSA and its treatment modalities. CLINICAL PRESENTATION: A 54-year-old man had a medical history of renal transplantation on his left external iliac artery. He complained of acute lumbar pain associated with cauda equina syndrome, which resolved within a few hours. At that time, a magnetic resonance imaging (MRI) scan revealed an intracanal hematoma extending from S1 to T12. Six weeks later, a second MRI scan demonstrated an oval-shaped intracanal mass behind the vertebral body of S1 with intense gadolinium enhancement. INTERVENTION: An anterior epidural mass was found. An incision into this mass resulted in significant arterial hemorrhaging. Transparietal embolization with a cotton compress and closure of the aneurysm wall were performed. The postoperative clinical status was stable, and a delayed angiographic study suggested a diagnosis of aneurysm of the right LSA, a branch of the internal iliac artery. Its pathophysiology was explained by the development of a high-flow transpelvic shunt from the right iliac artery territory to the left, to maintain the renal graft blood flow that had initially been reduced by stenosis of the left common iliac artery. Six weeks later, a new MRI scan demonstrated that the AnLSA had increased in size. The lesion was then excluded endovascularly by injection of glue. CONCLUSION: A medical history of renal transplantation with MRI scans showing an anterior epidural mass behind S1 or a spontaneous spinal epidural hematoma are features that must evoke a diagnosis of AnLSA. Treatment is mandatory and is best achieved by embolization. Surgery based on angiographic findings is indicated if the lesion is responsible for a compressive hematoma.

Orbital Meningioma

Background: Ectopic orbital meningiomas (OM) are a rare subset of OMs which are neither attached to the optic nerve sheath nor to the surrounding bone. Case Description: We report the case of a 65-year-old female who presented with a 1 year history of proptosis followed by visual loss and restricted right eye movements since 3 months. Radiology of the orbits was suggestive of intraorbital, intraconal, and heterogeneous contrast enhancing right eye lesion which was completely excised through supraorbital orbitotomy approach. Intraoperatively, the right optic nerve, though compressed, and displaced inferiorly, was free from the lesion. The final histopathological diagnosis was “Meningioma WHO Grade I.” At 3 months follow-up, patient’s vision in the right eye improved from perception of light positive to 6/12 and there was no evidence of recurrence. Conclusion: Rarity of ectopic OM, total surgical excision with an excellent postoperative visual outcome prompted us to report this case.

Optic nerve astrocytomas (ONAs) are frequent types of optic nerve gliomas (ONGs), which can affect the visual pathway. An 18-year-old male patient was admitted to our department with right-sided intraorbital/retrobulbar swelling, which progressively grew over several months. Clinical examination showed right-sided diplopia, mydriasis, low visual acuity (0.4), exophthalmus (3 cm), epiphora, and severe retrobulbar pain. There was a family history of high-grade (IV) astrocytomas in which two of the family members died due to the disease. Preoperative MRI scan revealed a soft tissue mass around the retrobulbar area of the right eye with intact orbital bony walls. Surgery was performed whereby it was dissected freely from the muscles and was separated from the optic nerve and the globe. Histopathologic analysis confirmed a benign astrocytoma. The follow-up examination revealed no recurrent or residual tumor. A systemic review of the literature indicates that early diagnosis and experienced multidisciplinary management are required in case of unilateral, resectable forms of ONAs with no distant metastasis, in order to provide a long-time survival of patients. Surgical intervention of unilateral ONAs is a relatively safe procedure, allowing complete or partial tumor removal with minimal morbidity and low recurrence rate.

This report describes a case of septic arthritis of the lumbar facet joint probably as a result of acupuncture treatment. A 48 year old man with a long history of back pain presented with a two week history of increasing pain following a third session of acupuncture. Examination revealed tenderness in the right lumbosacral area and laboratory investigations revealed raised inflammatory markers with negative blood cultures. A bone scan and MRI scan showed evidence of septic arthritis of the right L5/S1 facet joint. An x ray computed tomography guided biopsy was carried out which isolated staphylococcus aureus. The patient was initially treated with intravenous antibiotics. A repeat MRI scan demonstrated persistent septic arthritis with adjacent early abscess formation. Surgical debridement of the facet joint was therefore performed. The patient had resolution of his symptoms and the inflammatory markers returned to normal. He regained a full range of movement of the lumbar spine. Very few cases have been reported of lumbar facet joint septic arthritis and this condition is rare in association with acupuncture treatment. A high index of suspicion needs to be maintained and if conservative management fails then debridement can result in an acceptable outcome.

Optic disc pits are rare and congenital or acquired anomalies of the optic disc, usually remaining asymptomatic. However, serous macular detachment or optic disc maculopathy is the most common complication, causing significant visual deterioration, without a current consensus about treatment. A 55-year-old woman with a past medical history of diabetes mellitus and systemic hypertension was referred for an abnormal finding in the retina. The Corrected Distance Visual Acuity (CDVA) was 20/40 in the right eye and 20/30 in the left eye. Marcus-Gunn was negative and Slit-lamp biomicroscopy revealed no pathologic findings in both eyes. Funduscopic examination showed an excavation in the inferotemporal part of the Optic Nerve Head (ONH) with serous macular detachment extending to the optic disc. Based on clinical examination and paraclinical imaging fluorescein Angiogeraphy (FAG) Optical Coherence Tomography (OCT), optic pit maculopathy was diagnosed and the patient underwent Juxtapapillary Laser Photocoagulation (JLP). After 2 years of follow-up, there were anatomical and functional improvements.

Background. Osteochondritis dissecans (OCD) rarely occurs in multiple joints. Furthermore, the existence of left-right asymmetric OCDs in different joints of the contralateral side of the body and lesions occurring with a temporal difference is rare. Here, we report a rare case with multiple OCDs sequentially detected in various joints. Case Presentation. The 15-year-old male patient was referred to our hospital for an OCD in the medial femoral condyle of the left knee. He had a history of an OCD in his right elbow, and his father had a history of surgically treated OCDs in both knees. One year and five months after, surgery was performed to the lesion in his left medial femoral condyle, a new OCD lesion occurred in the femoral trochlea of the same knee, which was again treated surgically. Five months after the second surgery, the patient returned with pain in the right knee, and an OCD on the right femoral trochlea was detected by an MRI scan. This lesion remained stable without any further restriction in physical activities for 17 months until detachment occurred and was again treated surgically. Conclusion. In cases with history and a family history of multiple OCDs, in particular, with a short stature, an MRI scan should be performed for the symptomatic joint to detect and treat the lesion before progression.
