Abstract

Sinus pericranii is a rare vascular anomaly consisting of abnormal venous communication between intra- and extracranial circulation. We report one case, confirmed by surgery, and describe the radiological findings of Doppler ultrasonography, CT and MR imaging.

Keywords: Brain, abnormalities Brain, CT Brain, MR Brain, US

Fig. 1.

Postcontrast CT with bone window setting shows soft tissue mass (arrowheads) beneath the scalp. Underlying bone erosion with small bone defect (arrow) is also noted.

Fig. 2.

A. Axial T2-weighted MR image reveals a flat scalp mass of high signal intensity (arrows). There is a suspicious bone erosion in the underlying skull. B. Postcontrast Tl-weighted coronal image demonstrates a well enhancing mass (arrowheads) in right occipital area.

Fig. 3.

Color Doppler sonogram shows a diffuse hypoechoic mass (arrowheads) superficial to occipital bone (short arrows). There is an emissary vein (long arrow) in which venous flow was confirmed on pulsed Doppler study (not shown).
