Abstract

With improvement in imaging, CVT is being diagnosed more frequently. Early diagnosis and rapid institution of remedial measures such as anticoagulation, anticonvulsants, hydration, and treatment of underlying abnormality will aid in salvaging life. We report an autopsy case of a 34-year-old man who presented with sudden onset of seizures, followed by right hemiplegia and altered sensorium. Magnetic resonance imaging of the brain revealed intraparenchymal hemorrhage in the left posterior frontal region with a blood-fluid level. The SSS was devoid of the routine hypointense signal intensity. Routine evaluations for hypercoagulable states were negative. All the coagulation parameters were within normal limits. He was managed conservatively with anticonvulsants, anticoagulants, and hydration. A CT scan of the brain done 24 hours later revealed left posterior frontal hemorrhage with perilesional edema. A CT venogram confirmed the presence of CVT involving the SSS and the right transverse sinus. However he died within next 24 hours. An autopsy confirmed thrombosis in the SSS, right transverse sinus, lungs, and kidneys. Blood-fluid level in CVT may be an early radiologic sign in the absence of any other imaging abnormality. The presen...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Brain Injury & Trauma

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.
