A case of radionecrosis of the brain in a patient previously treated for squamous cell carcinoma of the scalp is presented. Cerebral angiography revealed a mass effect primarily in the right frontal area. Computed tomography showed extensive hemispheric oedema. A frontal lobectomy was performed, and the recovery was excellent. The lower limit for brain tolerance for irradiation is about 5000 ra...

introduction: toxoplasmosis is a parasitic infection cause by toxoplasma gondii. this parasite is associated with congenital infection and can cause abortion, encephalitis or systemic infection in immune- compromised patients. case presentation in this study, two cases of central nervous system toxoplasmosis in leukemia patients are reported. the first case was a 15-year-old girl with acute lym...

IgG4-related disease (IgG4-RD) is an emerging immune-mediated chronic fibrotic characterized by tumour-like mass formation. Reports of brain parenchymal involvement in IgG4-RD are rare and complete treatment-related remission lesions has never been reported. Here, we present a woman her mid-50s who developed headache seizures. Brain magnetic resonance imaging revealed frontal bilateral pachymen...

Spontaneous cervical epidural hematoma (SCEDH) is a rare disease, but can cause severe neurologic impairment. We report a case of a 68-year-old female who presented with sudden onset, posterior neck pain, right shoulder pain, and progressive right hemiparesis mimicking stroke with no trauma history. Initial brain CT and diffusion MRI performed to rule out brain lesion did not show any positive ...

intraluminal small bowel hematoma has been rarely reported in children, as a rare cause of small bowel obstruction. we present a case of an intraluminal ileal hematoma presenting as small bowel obstruction in a child. computed tomography (ct) indicated a large intraluminal hyperdense lesion in the distal ileum as the cause of small bowel obstruction. abdominal ultrasonography (us) showed an ech...

Lesion-deficit mapping remains the most powerful method for localising function in the human brain. As the highest court of appeal where competing theories of cerebral function conflict, it ought to be held to the most stringent inferential standards. Though at first sight elegantly transferable, the mass-univariate statistical framework popularized by functional imaging is demonstrably ill-sui...

We report the case of a giant hypothalamic hamartoma with a large intracranial cyst in a neonate. On ultrasonography, the lesion presented as a lobulated, mass-like lesion with similar echogenicity to the adjacent brain parenchyma, located anterior to the underdeveloped and compressed left temporal lobe, and presenting as an intracranial cyst in the left cerebral convexity without definite inte...
