ABSTRACT

Intracranial meningioma is one of the most easily detectable tumor in the preoperative period with the brain computerized tomographic(CT) scan. Although most of them are of benign nature, they present tendency to invade surrounding brain tissue and to recur in spite of complete surgical removal. Authors analysed the clinical features of 27 cases of histologically verified meningiomas and attempted to study the correlation between CT findings and histological types to predict their clinical invasiveness and aggressiveness. Female was predominated in occurance than male in the ratio of 17:10. Mean age of occurance was 40.5-year-old. The most frequent symptoms and signs were headache, papilledema and visual disturbance in order. The most frequent histological type was meningotheliomatous type(55.6%) which was followed by transitional(18.5%), fibroblastic(18.5%) and angioblastic(7.4%) types. In the finding of the brain CT scan, perifocal brain edema was noticed in nearly almost cases and high density of the tumor mass in the precontrast CT scan was predominated in transitional and fibroblastic types. But, marked perifocal brain edema, irregular tumor margin, loss of homogeneity of the tumor density and marked contrast enhancement, which were considered to be more aggressive and invasive findings, were predominated in the meningotheliomatous and angioblastic types. So, these types seemed to be more aggressive and invasive than other types. Large cystic meningiomas were 14.8% in author's cases.

ABSTRACT

Acoustic neurinoma are the most frequent tumors in the region of the cerebellopontine angle. They usually present with a gradual onset of symptoms and slow progression. Development of spontaneous hemorrhage with sudden aggravation of symptoms is rare. The authors present a case of acoustic neurinoma associated with a spontaneous intratumoral hemorrhage. Sudden aggravation of symptoms was noticed. The cranial computed tomography revealed multiple blood-fluid levels within the cysts of the tumor which was located in the region of the right cerebellopontine angle. Operation was performed, which confirmed recent hemorrhage within the tumor. Pathological study revealed a typical neurilemmoma associated with hemorrhage, vascular proliferation and macrophages which phagocytosed hemosiderin pigments. The rare sudden aggravation of symptoms in cases of acoustic neurinoma may suggest hemorrhage.
