A 47-year-old male receiving anticoagulant therapy for thrombophlebitis in the left leg for several years presented with mild left hemiparesis and ipsilateral hypesthesia. The cause of the thrombophlebitis was still unknown. Magnetic resonance (MR) imaging showed subacute thrombosis of both the superior sagittal sinus (SSS) and a cortical vein in the right(More)
A 67-year-old female with a history of hypertension and cerebral infarction presented with subarachnoid hemorrhage (SAH) (Hunt and Kosnik grade 4). Brain computed tomography (CT) revealed a clot dominantly on the right (Fisher's classification Group 4). Cerebral angiography showed funnel-shaped widenings at the origins of the bilateral posterior(More)
A 59-year-old male presented with a left organized subdural hematoma. The hematoma appeared as a homogeneous low density area on brain computed tomography and as hyperintense and isointense area on both fluid-attenuated inversion recovery and T2-weighted magnetic resonance (MR) imaging. Echo-planar diffusion-weighted MR imaging showed a crescent(More)
A 59-year-old diabetic male presented with transient motor aphasia and monoparesis of the right upper limb. Brain CT scan showed a low density area in the left subdural space with a mild midline shift. Magnetic resonance (MR) T2-weighted and fluid-attenuated inversion recovery (FLAIR) imagings revealed homogenous hyperintensity with a hypointense web-like(More)
Five cases of traumatic subdural hematomas in the subacute stage (from 7 to 20 days after head injury) were treated in one male and four females, aged from 63 to 82 years, with evacuation via craniotomy in three and aspiration via burr hole surgery in two. All hematomas were evaluated by T1-, T2-, and diffusion-weighted magnetic resonance imaging, and(More)
The diffusion-weighted magnetic resonance (MR) imaging characteristics of chronic subdural hematoma and the correlation between hematoma liquidity and apparent diffusion coefficient (ADC) were investigated in 26 consecutive patients, 16 males and 10 females aged 42 to 92 years (mean +/- SD 73.3 +/- 13.1 years), with 31 chronic subdural hematomas. The(More)
A 61-year-old female with a past history of gastric cancer presented with altered mental status, a few seizures, and low-grade fever. Lumbar puncture revealed elevated cerebrospinal fluid (CSF) pressure, lymphocytic pleocytosis, elevated protein level, remarkably decreased glucose level, and presence of cryptococcal antigen. Cryptococcus neoformans was(More)
A 47-year-old man with a history of thrombophlebitis of his left leg for several years presented with a mild left hemiparesis and ipsilateral hypesthesia. Magnetic resonance imaging showed subacute thrombosis of the superior sagittal sinus and a cortical vein of the right cerebral hemisphere. A linear hyperintense area was found in the white matter of the(More)
An 80-year-old male without abnormal past medical history presented with coma, general seizures, and fever subsequent to abnormal behavior. The pressure of the cerebrospinal fluid(CSF) elevated(13.5-20.5 cm H2O), and CSF examination revealed pleocytosis with predominant mononuclear cells(80-879/mm3) and elevated protein level(32-130 mg/dl). DNAs of herpes(More)
An 80-year-old male with a history of hypertension presented with chronic subdural hematoma manifesting as progressive consciousness disturbance and left hemiparesis. T1-weighted and fluid attenuation inversion recovery (FLAIR) magnetic resonance imaging showed a fresh hematoma in the right subdural space with a midline shift of 15 mm. FLAIR and(More)
