Sinus Pericranii: CT and Color Doppler Ultrasound Imaging Findings in a Case of Spontaneous Thrombosis

Sinus pericranii: clinical and imaging findings in two cases of spontaneous partial thrombosis.

Sinus pericranii is an unusual venous anomaly characterized by communication of pericranial varicosities with an underlying dural sinus. We report two cases of spontaneous partial thrombosis of sinus pericranii presenting as focally tender, nonreducible mass lesions different in character from the baseline venous abnormality. CT, CT angiography, and CT venography (CTV) were performed in both ca...

Sinus pericranii: color Doppler ultrasonographic findings.

inus pericranii is a rare abnormality that may appear as a midline nasofrontal mass.1,2 This disorder consists of congenital or acquired anomalous connections between an extracranial blood-filled nodule and the intracranial dural sinuses through dilated diploic and emissary veins of the skull.3 We report a case of sinus pericranii and present the findings on color Doppler ultrasonography (CDUS).

Spontaneous Intracranial Hypotension Plus Cerebral Venous Thrombosis: A Case Report Study

This is a case study of a 34-year-old woman who was admitted to hospital with a history of severe orthostatic headache. She was diagnosed as having spontaneous intracranial hypotension (SIH) by undetectable cerebrospinal fluid (CSF) pressure at lumbar puncture, and with evidence of diffuse dural enhancement of the brain detected by magnetic resonance imaging (MRI). However, the contrast-enhance...

MR Imaging and Angiographic Findings

curs in the pediatric age group. Ohta et al. (1) defined this condition as “a collection of nonmuscular venous blood vessels or venous hemangiomas adhering tightly to the outer surface of the skull bone and directly communicating with an intracranial venous sinus by way of many diploic veins of several sizes.” To our knowledge, few reports published in Korea have described the MR imaging and MR...
