“…Currently, histological grading based on the World Health Organization (WHO) classification has been used. 3 Accordingly, grade I tumors have a low risk of recurrence or aggressive growth and include histological subtypes, namely meningothelial (syncytial), fibrous (fibroblastic), transitional (mixed), psammomatous, angiomatous, microcystic, secretory, lymphoplasmacyte-rich and metaplastic. Grade II tumors have a greater possibility of recurrence and/or aggressive behavior with histological subtypes of atypical, clear cell (intracranial) and chordoid.…”

Aim: Meningioma is a benign intracranial tumor. Occurrence of ectopic meningioma in maxillary alveolar ridge is very rare. Our aim is to add another case of ectopic meningioma in the maxillary alveolar ridge to the literature.Background: Meningioma is a benign tumor that originates from meningocytes found in arachnoid villous structures of the meninges. The tumor is rarely seen in extracranial locations from the oral cavity.

“…Meningioma is a common intracranial tumor with a variety of histomorphologic growth patterns, which are usually easily recognized (5). Meningiomas constitute about 20% to 30% of all primitive brain tumors (6). Most meningiomas are benign, ie, classic or grade I, well circumscribed, slow growing, and depending on their location, curable by surgery (7).…”

Introduction: Many conditions can mimic psychiatric symptoms. Amongst them, intracranial mass and space occupying lesions have a significant importance. Aggression and hallucination are seen in association with a basal frontal lesion, and may mimic psychotic syndromes. Case Presentation: A 37-year-old man with no previous mental illness presented with a month history of headache, blurred vision, diplopia, aggression, loss of interest, fatigue, insomnia, and depressed mood. He was suffering from daily auditory hallucination which described as musical hallucination lasting about an hour per day. The headache was tension-type which appeared swinging, two times per week lasting 30 minutes. After auditory hallucination, the patient disclosed nausea, vomiting, and transient loss of consciousness. He referred from a neurologist, because, conventional therapy for the patient had not response. There were no other neurological symptoms or deficits. The results of neurologic examination including evaluation of the cranial nerves as well as head and neck examination were normal; But, psychiatric symptoms developed. Therefore, he was admitted to the psychiatric ward. The patient was diagnosed with major depressive disorder (MDD) with psychotic feature by Diagnostic and Statistical Manual of Mental Disorders (DSM) IV criteria and received psychiatric treatment. He started on antipsychotic agent (olanzapine 5 mg tablet/bid), antidepressant (sertraline 50 mg tablet/qhs) and valproate sodium 200 mg tablet/bid for treatment of aggression and headaches. After five days of admission, primary symptoms of headache and auditory hallucination were better but diplopia and blurred vision were still present. Ophthalmology examination revealed. The pupils were round, isochoric, and normoreactive to light and accommodation, and there was no sign of a relative afferent pupillary defect. Ophthalmoscopy showed a papilledema in both eyes. In order to rule out the intracranial pressure and their causes, neuroimaging was requested. An emergent noncontrast-enhanced computed tomography (CT) image of the head revealed a hyperdense mass in midfrontal convexity. Magnetic resonance imaging of the brain and orbits with and without intravenous gadolinium enhancement further delineated the CT findings and highlighted a large avidly enhancing midline mass within the frontal region measuring approximately 48×50×42 mm in axial dimension, consistent with a meningioma. The patient discharged from psychiatric ward with necessary advices and was admitted to the neurosurgery ward for further evaluation. A first psychosis episode is a clinical condition with principal indication for cerebral CT-scan. Discussion: Meningioma is a common intracranial tumor with a variety of histomorphologic growth patterns, which are usually easily recognized. The three most common symptoms are headaches, mental status changes, and paresis. Aggression and hallucination are seen in association with a basal frontal lesion and may mimic psychotic syndromes like hypomania and schizophren...

“…The typical MR imaging features of meningiomas are isointense or hypointense on T1-WI and isointense or hypointense on T2-weighted images and exhibit marked homogeneous contrast enhancement. On T2-weighted images, fibroblastic and transitional meningiomas are isointense to hypointense, but angiomatous and meningothelial meningiomas are usually hyperintense [46].…”

Computed tomography and magnetic resonance imaging of lesions at masticator space

We aim to review the normal anatomy and imaging appearance of masticator space lesions. Because the masticator space is not amenable to direct examination, cross-sectional imaging with computed tomography and magnetic resonance imaging play an important role in diagnosis and characterization of lesions occurring there. Masticator space lesions can be classified on the basis of their origin into the following categories: inflammatory lesions, benign tumors, malignant tumors, vascular lesions, and developmental lesions. A diverse spectrum of malignant tumors and benign lesions are seen extending from the adjacent spaces. In addition, one should also be familiar with pseudolesions as well as post-treatment changes in the masticator space that can be mistaken for pathologic conditions.
