Open magnetic resonance imaging of a 45-year-old man with panic disorder showed a sinus pericranii (SP). Examination of the scalp revealed a discolored scalp mass, and magnetic resonance venography displayed a hypoplastic straight sinus with persistent falcine sinus.SP is a venous anomaly consisting of a transosseous vascular channel connecting an intracranial sinus with subgaleal veins. High venous pressure in the late embryonic stage, as with a hypoplastic straight sinus, has been hypothesized to predispose affected individuals to develop other venous anomalies (i.e., falcine sinus).Because there is no major venous outflow through this accessory SP in an asymptomatic adult, no intervention was recommended for our patient.
