We also reviewed the etiology, clinical features, and therapeutic aspects of this neurological emergency. Ten patients, five males and five females, with clinical findings suggestive of DST were examined using magnetic resonance imaging (MRI) and venous MRA. The main symptom in adults (n=8, age: 17-55) was headache. Visual loss, convulsions, and motor signs were present in two infants. Three patients had chronic renal failure and were on a hemodialysis program. One patient was diagnosed with Behçet's disease, and another was in the postpartum period. Both infants had congenital heart disease. Infection accompanied DST in four patients. MRI revealed edema and white matter signal abnormalities in four patients. Venous MRA showed superior sagittal sinus thrombosis in 6 patients, and lateral sinus thrombosis in 10 patients. All the patients were anticoagulated, and those with infection were given antibiotic treatment. In six patients, follow-up venous MRA and/or MRI revealed recanalization. No mortality or morbidity was documented in the adults. Venous MRA and MRI are noninvasive, sensitive, and reliable techniques for early diagnosis and follow-up of DST.
