PURPOSE To evaluate the imaging findings, possible pathogenesis, and frequency of hemorrhage near the tentorial surface of the cerebellum after supratentorial surgery. METHODS Over a 5-year period, 13 patients with posterior fossa hemorrhage after supratentorial surgery were identified with postoperative CT studies, which were obtained in all patients after craniotomy. Four of the 13 patients...

TO THE EDITOR: In the April issue of the Journal of Clinical Oncology, Timmermann et al suggest that radiotherapy plays a major role in the treatment of young children with supratentorial primitive neuroectodermal tumors (stPNET) and conclude that a delay in irradiation may compromise survival. Although stPNET are undoubtedly aggressive brain tumors and results of treatments are still disappoin...

MR imaging in seven patients (4 days to 38 months old) with nonketotic hyperglycinemia showed age-related findings of progressive atrophy and delayed myelination. Parenchymal volume loss was found as early as 4 days after birth and increased in severity with increasing age to 27 months. Both supratentorial and infratentorial volume loss were present in the most severely affected patients. The c...

Multiple pyogenic brain abscesses constituted 11.7% (21 patients) of a series of 179 consecutive patients with brain abscess treated from 1976 to 1984. The commonest cause of these abscesses was congenital cyanotic heart disease (38%), followed by middle ear infection (19%). Two thirds of these patients were in the first two decades of life. The clinical presentation was similar to brain absces...

Ataxia-telangiectasia, an autosomal recessive disorder caused by defect of the ataxia-telangiectasia mutated gene, is characterized by progressive neurologic impairment with cerebellar atrophy, ocular and cutaneous telangiectasia, immunodeficiency, heightened sensitivity to ionizing radiation and susceptibility to developing lymphoreticular malignancy. Supratentorial brain abnormalities have be...

Hemangioblastomas are sporadic tumors found in the cerebellum or spinal cord. Supratentorial hemangioblastomas are rare, and those with meningeal involvement are extremely rare and have been reported in only approximately 130 patients. Here, we report the case of a 51-year-old female patient with supratentorial meningeal hemangioblastoma detected 5 years after surgical resection of an infratent...

BACKGROUND AND PURPOSE Cerebellar atrophy is considered the most prominent neuroradiologic finding in Marinesco-Sjögren syndrome (MSS). Our purpose was to investigate this neuroradiologic feature in a series of patients with MSS. METHODS Five patients with MSS (age range, 5-19 years) underwent native MR imaging of the brain. The findings were assessed with particular attention to the cerebell...

Two adults, 31 and 20 years of age, developed supratentorial metastasis 3½ years and 11 months, respectively, after gross total removal of their posterior fossa medulloblastoma. The first case developed spinal metastasis as well. Both had undergone craniospinal irradiation. Case 1 underwent laminectomy and case 2 underwent craniotomy because their presenting symptoms required so.

DESCRIPTION A 65-year-old woman comes for headache management. Few years ago, she was diagnosed with a ‘single benign tumour of the anterior part of the brain’. A new contrast CT brain scan was done (figures 1 and 2); as she was claustrophobic, brain MRI was not ordered. The mass they have referred to was most likely a falcine meningioma. In addition, there is an oval hyperdense mass at the rig...
