Can intravascular lymphomatosis mimic sinus thrombosis? A case report with 8 months' follow-up and fatal outcome.

We report a case of intravascular lymphomatosis of the brain with 8 months' follow-up and fatal outcome. Several MRI investigations revealed variegated, rapidly changing infarct-like lesions and invasion of the walls of the superior sagittal sinus and deep veins. When disturbances of the venous outflow are detected with multifocal infarct-like lesions, intravascular lymphomatosis should be considered in the differential diagnosis. Brain biopsy may ensure the proper diagnosis ante mortem, but failure of biopsy is frequent, as in our case.

Superior sagittal sinus thrombosis associated with primary antiphospholipid syndrome--case report.

A 36-year-old female with a history of recurrent pregnancy loss experienced sudden onset of disturbance in consciousness, with right hemiparesis and total aphasia. Computed tomography revealed a massive hemorrhage in the left frontal lobe, and angiography showed occlusion of the anterior two-thirds of the superior sagittal sinus. Laboratory investigations detected the presence of lupus anticoagulant, elevation of the anticardiolipin beta 2-glycoprotein I complex antibody level, and a decreased protein S activity level. There were no underlying conditions, such as connective tissue disorders, malignancies, infectious diseases, and drug-induced disorders, so the diagnosis was primary antiphospholipid syndrome. Primary antiphospholipid syndrome should be considered in the evaluation of patients with "idiopathic" or "primary" sinus and cerebral venous thrombosis.

Lumbar puncture and dural sinus thrombosis--a causal or casual association?

BACKGROUND: A few cases of cerebral venous thrombosis (CVT) were reported after a lumbar puncture (LP), suggesting a causal association. The purpose of our study was to document that LP might predispose to CVT by decreasing blood flow velocities (BFV) in veins or dural sinus. METHODS: We performed a transcranial Doppler ultrasound study to register the mean BFV of the straight sinus (SS) before, during and after LP. RESULTS: Thirteen patients were studied. LP induced a decrease of 47% of mean BFV in the SS. The mean decrease of BFV was significant immediately at the end (p = 0.003), 30 min after (p = 0.015) and more than 6 h after LP (p = 0.008). CONCLUSIONS: LP induced a sustained decrease of mean BFV in the SS. The decrease of venous blood flow is a possible mechanism contributing to the occurrence of CVT.
