A 6-year-old boy, with no past medical history, presented with progressive headache, vomiting, right side weakness since 3 months without fever or seizures. On examination, he was conscious with a stiff neck and right hemiplegia. Brain computed tomography-scan showed a heterogeneous calcified large mass-like lesion in the left fronto-temporo-parietal region, irregular contrast enhancement and e...

abstract the intraparenchymal schwannomas are very rare tumors with only 52 reported cases . we describe a 38 years old man with eight months history of poorly controlled seizures despite of medical therapy. on brain ct scan a 1.5 x 1.5 cm hypodense enhancing lesion was seen in right posterior-inferior frontal lobe. on brain mri the lesion was hypointense in t1 and hyperintense in t2 with homog...

    Abstract   The Intraparenchymal schwannomas are very rare tumors with only 52 reported   cases . We describe a 38 years old man with eight months history of poorly controlled   seizures despite of medical therapy. On brain CT scan a 1.5 x 1.5 cm hypodense enhancing lesion was seen in right posterior-inferior frontal lobe. On brain MRI the lesion   was hypointense in T1 and hyperintense in T...

BUMC PROCEEDINGS 2000;13:424–429 CASE PRESENTATION J. TODD GAGE, MD: A 32-year-old African American man with AIDS was brought to the emergency department of Baylor University Medical Center. Shortly before breakfast on the day of admission, the patient had abruptly lost consciousness and experienced a tonicclonic seizure, which lasted several minutes and resolved spontaneously. No head trauma, ...

BACKGROUND For cases of severe traumatic brain injury, during primary operation, neurosurgeons usually face a dilemma of whether or not to remove the bone flap after mass lesion evacuation. Decompressive craniectomy, which involves expansion of fixed cranial cavity, is used to treat intra-operative brain swelling and post-operative malignant intracranial hypertension. However, due to indefinite...

The morphology of supratentorial malignant glioma was examined in autopsy brains from three anaplastic astrocytoma and 11 glioblastoma multiforme patients. Large histological preparations and routine preparations were used to investigate the primary lesion site, infiltration to adjacent brain, and cerebrospinal fluid (CSF) dissemination. The primary lesion sites showed active tumor growth with ...

A 52-year-old female presented with an unusual large cystic cavernous angioma with dense calcification in the thalamus manifesting only as headache despite the large mass with surrounding brain edema. Both T1- and T2-weighted magnetic resonance images revealed a large cystic mass with an intramural nodule appearing a reticulated, irregular mixed intensity core. The lesion was totally removed th...

A cat with a history of seizures and clinical suspicion of forebrain disorder underwent a brain magnetic resonance imaging. A space-occupying lesion was identified in the left temporal lobe. The mass was surgically removed, and cytological, histological and immunohistochemical examinations documented the presence of Toxoplasma gondii. A definitive diagnosis of an intracranial T gondii granuloma...

-Detailed analyses of "subgroups" of Ss, defined by lesion size and locus, for Lashley's (1929) retention data suggested that parietal neo-cortical damage resulted in deficits that were relatively independent of total lesion size. It was suggested that Lashley's retention data provided questionable support for the principles of equipotentiality and mass function as he presented them and he did ...
