Infections of the nervous system and its belonging structures have often been reported as life-threatening conditions. Purpose: the results of dynamic follow-up and proving of changes in secondary meningoencephalitis from suppurative left maxillary sinusitis are presented using the imaging methods - CT and MRI. Methods: diagnostic imaging (CT, MRI), of acute disease in a 13-year-old child with progressive development and proving of secondary bacterial meningoencephalitis. Result: the control CT after two days showed dynamics in the imaging CT finding with the appearance of changes in the type of brain oedema and development of pansinusitis. The MRI data described corresponded to changes as at meningoencephalitis in progress.Conclusion: The extension of the diagnostic algorithm with MRI, with the administration of intravenous contrast medium, clearly demonstrated changes characteristic of meningoencephalitis.

Bone-related disorders of the jaw (BRDJ) include a spectrum of non-neoplastic and neoplastic lesions of the maxillofacial region that have been recently classified into fibro-osseous lesions, giant cell lesions and osseous tumours. The histopathological features of BRDJ can be similar and overlie each other. Imaging is important in order to reach a specific diagnosis. However, the appearance of BRDJ on imaging is non-specific in some cases. Computed tomography (CT) and magnetic resonance imaging (MRI) are used for accurate localisation, characterisation of the tumour matrix, delineation of the lesion extension and establishment of the relation of BRDJ to the surrounding structures. Imaging is usually done to detect the relationship with the adjacent surrounding vital structures and to diagnose aggressive forms, malignant transformation and associated syndromes. The correlation of the demographic findings, the location and the clinical presentations with the imaging features are important for the diagnosis of BRDJ. The proposed clinico-radiological diagnostic algorithm with CT and MRI helps a specific diagnosis to be reached in some cases.

Abstract OBJECTIVE AND IMPORTANCE: Angioleiomyomas (ALMs) are relatively rare, benign, vascular soft tissue tumors that occur most frequently in the extremities of middle-aged individuals. To date, only two cases of intracranial ALMs have been described, both with little emphasis on the clinical, surgical, and radiological aspects. Neither of these reported cases of ALM involved the cavernous sinus. Furthermore, there is no previous intracranial ALM magnetic resonance imaging scan described in the literature. This report presents the first case of cavernous sinus ALM, emphasizing the clinical, radiological, and surgical aspects. CLINICAL PRESENTATION: A 52-year-old man had a 2-year history of horizontal diplopia and frontal headache. Facial numbness and impaired visual acuity in the previous 6 months were also reported. Physical examination revealed paralysis of right Cranial Nerves III, IV, and VI. A decrease in optical acuity was also noted. Computed tomographic and magnetic resonance imaging scans demonstrated a mass lesion located in the right cavernous sinus, which enhanced homogeneously with administration of intravenous contrast medium. INTERVENTION: A total resection was performed via a right frontotemporal craniotomy and a pretemporal approach with peeling of the middle fossa. The postoperative course was uneventful. Histological examination identified the ALM, with no recurrence noted during follow-up. CONCLUSION: It is unknown why intracranial ALMs have not been reported more frequently in the literature. Although ALMs are a rare occurrence, misinterpretation of this lesion may also have contributed to the lack of reported cases. Before surgery, ALMs can be distinguished from meningiomas and schwannomas but not from hemangiomas. The prognosis of intracranial ALM is good, as suggested in this case as well as the two previously reported cases.

This report concerns a clinical trial with gadolinium-DTPA (Gd-DTPA) as an intravenous contrast medium for magnetic resonance imaging (MRI) in patients with disorders of the central nervous system. Fifty patients, 30 females and 20 males, were examined without and with Gd-DTPA. The contrast medium was well tolerated by all patients. The results of MRI scanning without and with Gd-DTPA and those obtained with computed tomography (CT) using intravenous contrast enhancement were compared. This investigation comprised mainly patients with intracranial tumors, multiple sclerosis, and nasopharyngeal tumors. The results may be summarized as follows: 1) MRI with Gd-DTPA (MRI+) gave better results than MRI without Gd as regards delineation of the lesion, blood vessels and edema in cerebral tumors, pituitary adenomas and acute forms of multiple sclerosis (MS). 2) MRI+ was better than CT in 32 of the 50 cases examined; with intracerebral tumors it was better in 15 out of 18 cases. 3) MRI+ was always better than CT in patients with MS. In 3 out of 7 cases MRI demonstrated the acute MS lesions. 4) MRI+ seemed to have advantages also in nasopharyngeal tumors as ascertained from this limited experience.

✓Acquired intradural arachnoid cystic lesions of the spine have been associated with trauma, hemorrhage, parasitic infections, and other insults that cause inflammation and subarachnoid adhesions. The authors describe the case of a previously healthy 36-year-old woman who presented with a chronic myelopathy due to the progressive development of a giant spinal arachnoid cyst that resulted after the intrathecal injection of phenol for the management of chronic upper extremity pain. Neurological examination, spinal computed tomography, and magnetic resonance imaging were used for diagnostic and follow-up purposes. Even after the initial excision of the cyst, the patient remained symptomatic with minimal functional recovery.

From 1982 to 1992, 65 patients presented to our service with sinusitis complications. In this report we will analyze our clinical material with emphasis on the type of complications, clinical presentations, and radiologic findings. The most common complication was orbital (83.1%), followed by intracranial (18.5%) and bony (7.7%). There was a higher incidence of complications in the second decade of life (44.6%), and 83.2% of the cases occurred in the third decade of life. The main complaints were orbital swelling (63.1%), fever (33.8%), headache (32.3%), and rhinorrhea (21.5%). The predominant signs were eyelid swelling (73.8%) and rhinorrhea (64.6%). The most frequent radiologic findings (x-ray, CT, MRI) were pansinusitis (40%), maxilloethmoidal sinusitis (24.6%), and maxillary sinusitis (13.8%). All patients were treated with intravenous antibiotics, and surgery was performed in 50.8% of the patients. Almost all patients (98.5%) had a good outcome, and one patient died (cavernous sinus thrombosis). Complicated sinusitis can be a life-threatening condition. CT and MRI are a great aid in the diagnosis of these complications.

Transsphenoidal Resection

Benign notochordal cell tumors (BNCTs) are considered to be benign intraosseous lesions of notochord origin; however, recent spine studies have suggested the possibility that some chordomas arise from BNCTs. Here, the authors describe two cases demonstrating histological features of BNCT and concomitant chordoma involving the clivus, which, to the best of the authors’ knowledge, have not been previously documented at this anatomical site.An 18-year-old female presented with an incidentally discovered clival mass. Magnetic resonance imaging revealed a 2.8-cm nonenhancing lesion in the upper clivus that was T2 hyperintense and T1 hypointense. She underwent an uneventful endoscopic transsphenoidal resection. Histologically, the tumor demonstrated areas of classic chordoma and a distinct intraosseous BNCT component. The patient completed adjuvant radiation therapy. Follow-up showed no recurrence at 18 months.A 39-year-old male presented with an incidentally discovered 2.8-cm clival lesion. The nonenhancing mass was T2 hyperintense and T1 hypointense. Surgical removal of the lesion was performed through an endoscopic transsphenoidal approach. Histological analysis revealed areas of BNCT with typical features of chordoma. Follow-up did not demonstrate recurrence at 4 years.These cases document histologically concomitant BNCT and chordoma involving the clivus, suggesting that the BNCT component may be a precursor of chordoma.
