چکیده
Antonetta Margaretha Gezina Sas, MD Fop van Kooten, PhD An 18-year-old woman was referred for a slowly growing tumor on her scalp, which had been present since her birth. Examination revealed a soft-tissue non-pulsating mass on her scalp (figure 1) which became larger in recumbent position and with Valsalva maneuver. CT showed that almost the entire venous system drained through enlarged parietal foramina with dilated emissary veins connected to multiple subcutaneous veins, which is called sinus pericranii (SP) (figure 2). Generally, SP is located frontally in

Sinus Pericranii: CT and Color Doppler Ultrasound Imaging Findings in a Case of Spontaneous Thrombosis
Sinus pericranii (SP) is an unusual venous anomaly characterized by communication of pericranial varicosities with an underlying dural sinus. We report a case of spontaneous thrombosis of sinus pericranii presenting as focally tender, nonreducible mass lesion different in character from the baseline venous abnormality. CT and colour Doppler Imaging were performed.

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...
متن کاملSinus 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).
متن کاملSinus pericranii with dural venous lakes.
Cavernous hemangiomas involving the dura are relatively uncommon lesions . We report a case of a cavernous hemangioma with features of sinus pericranii with venous lakes that involved the dura as well as calvarium. Associated with it were radiologic bone changes atypical for hemangioma. In presenting our case, we correlate the computed tomographic (CT) appearance with surgical and conventional ...
متن کاملA rare case of diploic venous anomaly: asymptomatic venous sac expanding in the diploe
BACKGROUND Vascular anomalies accompanied with the diploic veins are rare. Among them, sinus pericranii, which is characterized by abnormal connections between intra- and extracranial venous systems, is relatively common. Besides sinus pericranii, a few cases of subepicranial varix with connections to diploic veins have been reported, but these varices had no connections to intracranial venous ...
