Abstract
BACKGROUND: The coexistence of venous anomalies, such as vertical embryonic positioning of the straight sinus (VEP of SS), has been reported in patients with atretic cephalocele (AC). VEP of SS has been exclusively encountered when the AC is found above the torcular. CLINICAL PRESENTATION: We report a patient with suboccipital AC associated with venous anomalies analogous to VEP of SS, consisted of the Galenic venous system which did not drain into the straight sinus in the tentorium, but into the falcine sinus instead. Differences with VEP of SS in our case had no anatomical relationship between the falcine sinus and the suboccipital AC and no large cerebrospinal fluid space around the falcine sinus. A detailed neuroradiological examination was helpful for detecting these minute anomalies.
