ABSTRACTHemifacial Spasm (HS) occurs idiopathically or secondary to the lesions compressing the root exit zone of the facial nerve symptomatically. Symptomatic HS is generally due to vascular compression. We report on a 23-year-old male with right sided HS for a month. Magnetic resonance imaging (MRI) of the brain revealed a well-demarcated epidermoid cyst in the right cerebellopontine cistern. It was hypointense on T1-weighted imaging, hyperintense on T2-weighted imaging without contrast enhancement, hyperintense on DWI, and slightly hypointense on ADC relative to the brain. Although it caused shifting of the pons and medulla to the left side and compression of the right cerebellar peduncles and fourth ventricle, the sole symptom of the patient was HS. Clinicians are advised to request MRI/scan for brainstem lesions from the patients with HS. Epidermoid cysts in cerebellopontine cistern may present with HS as the sole symptom.

We present a case of an immunocompetent patient who developed Aspergillus meningitis, subsequent to discitis, presumed to be from an epidural steroid injection. Magnetic resonance imaging (MRI) of the lumbar spine confirmed the diagnosis of discitis. Fluoroscopic-guided aspiration of the disc showed growth of Aspergillus fumigatus. MRI of the brain revealed involvement of the right third cranial nerve. Repeat MRIs demonstrated multiple leptomeningeal masses consistent with granulomatous meningitis. Meningitis is a rare complication of discitis, discogram, or epidural steroid injection. Aspergillus usually only infects immunocompromised patients, but rarely can affect immunocompetent patients.

This case series reports familial cases of nodular oncocytic hyperplasia (NOH) diagnosed in a mother and her son, 15 years apart. A 39-year-old man presented in 2003 with a lump below his left ear. Magnetic resonance imaging (MRI) performed showed multifocal parotid nodules and a diagnosis of NOH was histopathologically confirmed following left total parotidectomy. Two years later, he represented with similar symptoms on the right side. NOH was diagnosed following excision of his right parotid gland. In 2018, his 73-year-old mother presented with left ear pain and a lump below her left ear. An MRI scan showed multiple lesions within both parotid glands and bilateral NOH was once again diagnosed following a left superficial parotidectomy and right total parotidectomy. We believe that this is the first reported case of bilateral familial NOH.

Gardner Syndrome is a rare disease with clinical manifestations of familial intestinal polyposis with osteomas. Cutaneous and subcutaneous lesions are common and epidermoid cyst is a characteristic dermatologic finding. This case report presents a novel finding of an intracranial epidermoid situated in the fourth ventricle in a patient with Gardner Syndrome. This intracranial epidermoid has been followed with sequential magnetic resonance imaging (MRI) for 10 years with progressive growth of the lesion. This suggests the conservative management is an option in patients with an enlarging epidermoid cyst in the fourth ventricle. Plain language summary Non-operative treatment of a cyst in the brain in a syndrome called Gardner syndrome. What is Gardner syndrome? Gardner syndrome is a rare disease and form of familial adenomatous polyposis (FAP) that is characterized by multiple small growths of cells (polyps) in the colon and various types of tumors, both noncancerous (benign) and cancerous (malignant). It is caused by changes (mutations) in the APC gene. Abnormal changes on the skin and under the skin are common as well as growths called epidermoid cysts. The cysts develop when cells that are meant to become skin, hair, and nails (epithelial cells) are trapped among the cells that form the brain. Epidermoid brain cysts may be diagnosed by magnetic resonance imaging (MRI) and computerized tomography (CT) scans. Typical treatment usually involves surgery. What was the aim of this case report? To present a different management strategy for patients with Gardner Syndrome with epidermoid brain cysts. How was this patient treated? This patient is the first patient with Gardner Syndrome with a very rare epidermoid brain cyst reported to be treated in a conservative manner. The patient was monitored for 10 years with regular MRI scans and the cyst continued to grow over this time. Despite this growth the patient has shown no signs of a buildup of fluid in the cavities deep within the brain (called hydrocephalus). The patient experienced nonfocal headaches, which were relieved with medication so doctors decided not to surgically remove the cyst. Why is this case important? Conservative management of epidermoid brain cysts in Gardner patients has not been reported before. This case report shows that conservative management may be an alternative option for patients with a growing epidermoid cyst in the fourth ventricle of the brain. Conservative treatment is designed to avoid invasive treatments or surgery and provides a different option for patients who are unable to have surgery.

AbstractA 79-year-old patient was admitted to the emergency room with transitory monoparesis in the left hand and dysphasia. The brain computed tomography (CT) and magnetic resonance imaging (MRI) showed a spontaneous right convexity subarachnoid hemorrhage (cSAH). Digital subtraction angiography (DSA) confirmed an asymptomatic occlusion of the right internal carotid artery (ICA) . Cases related to stenosis have already been described, but there is no similar report of a case related to occlusion, even though the pathophysiology of both entities is similar. Atraumatic SAH has been associated with intracranial and extracranial artery stenosis.

Metronidazole Induced Encephalopathy (MIE) is rare and serious central nervous system toxicity. A 40-year-old male, on long-term self treatment with metronidazole (cumulative dose: 102 gm) presented with dysarthria, nystagmus, unsteadiness, and numbness in both legs. A Magnetic Resonance Imaging (MRI) scan of the brain revealed a symmetric hyperintensity in both the dentate nuclei of cerebellum on both T2 weighted and Fluid-Attenuated Inversion-Recovery (FLAIR) imaging. Discontinuation of metronidazole resulted in resolution of the imaging findings and clinical improvement occurred within one month. Metronidazole-induced neurotoxicity should be considered in patient who present with cerebellar symptoms and characteristic lesion on MRI in close temporal relation with metronidazole intake and drug should be discontinued to prevent permanent neurological deficit.

A case of synchronous cystic teratomas presented with the complaints of a slow-growing facial mass and forward protrusion of the right eye since birth. The patient was examined thoroughly and subjected to magnetic resonance imaging (MRI) scan. The MRI scan revealed the presence of two separate cysts in the right orbit and right temporal fossa. The patient was operated by a combined effort of ophthalmologists and otorhinolaryngologists. The cysts were excised and subjected to pathological examination. The histopathological survey revealed both the cysts to be mature cystic teratomas similar to each other. This coexistence of a primary temporal fossa teratoma with an orbital teratoma is the first of its kind and to the best of our knowledge has not been reported before.

Brain Template

Brain research is challenging. One of the standard research methods is electroencephalography (EEG). As a rule, this study is presented in the form of graphs. This article describes an approach in which this data is mapped onto a brain model generated from a magnetic resonance imaging (MRI) scan. This allows you to look at the EEG study from a different point of view. An MRI scan will also allow you to take into account some of the features of the brain. This is an advantage over mapping just to a brain template. This non-invasive system can be implemented to monitor the patient in real-time, for example, during space flight.

: This study aimed to present a case of a clinically isolated syndrome (CIS) with a reported tumefactive demyelinating lesion (TDLs) in the cord. The patient was a 25-year-old woman who referred to MS Clinic complaining of walking impairment and a blurred vision in the right eye. In the magnetic resonance imaging (MRI) of the brain, there were several periventricular plaques, a significant portion of which had enhanced, but none of the lesions was tumefactive. In the cervical MRI, however, several tumefactive plaques appeared with a clear enhancement and expansion, which was central-based in the axial view. Concerning the involvement of the cervical cord, further examinations were conducted of anti-aquaporin and anti-myelin oligodendrocyte glycoprotein (MOG) antibodies, which were negative. The patient was treated with 1g methylprednisolone daily injection for five days; her symptoms recovered completely. Then, due to the extent of the involvement, rituximab was prescribed for her. Unlike the TDLs of the brain, little attention has been paid to these lesions in the cord. Here, firstly a case of CIS with a tumefactive lesion reported in the cord is investigated, and then, by examining similar cases, we try to find a definition for cord TDLs.

A 13-month-old, neutered, male Golden retriever presented with seizures and progressive depression. Clinical and neurological assessment was consistent with severe intracranial disease. The neurological condition progressively deteriorated and magnetic resonance imaging (MRI) revealed the presence of a large, contrast-enhancing, space-occupying mass in the right cerebral hemisphere. Therapy with corticosteroids, mannitol and furosemide ameliorated the signs of depression and ataxia, but the owner elected euthanasia after 1 week. Post mortem examination of the brain confirmed the presence of a large haemorrhagic lesion in the right olfactory lobe, the histopathological appearance of which was consistent with cerebral cavernous haemangioma. This is the 1st case describing the MRI appearance of a cavernous haemangioma of the cerebrum in the veterinary literature.

A 30-year-old woman presented to our outpatient department with complaints of pain and swelling in bilateral infrapatellar regions and a discharging sinus in the right knee over the duration of one year. Radiographs showed lytic regions in bilateral patellae. Samples sent from material curetted from sinus yielded no organism but histopathology reported granulomatous inflammation. Following a fresh magnetic resonance imaging (MRI) scan that revealed the infrapatellar pad of fat communicating with the patellar lesions, an exploration and evacuation was done. Material sent revealed epithelioid cell granulomas with caseous necrosis consistent with tuberculosis (TB). The patient was put on first line anti-tubercular treatment (ATT) and has responded favourably with healing of sinus and patellar lesions. Bilateral infrapatellar bursitis is not rare. However patellar TB as a cause for OMIT is not a common diagnosis. A bilateral patellar involvement has not been reported in literature to the best of our knowledge.
