Abstract

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

Figure

• 

  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).
