CT
Presence of multiple tubular-like tortuose hyperdense lesions occupying the left fronto-temporal region to represent the nidus. Some of these lesions have peripheral mural calcifications. A large tubular hyperdense structure extends from the lesions into the left ambient cistern and left quadrigeminal cistern and further into straight sinus, suggestive of draining vein.
These lesions exert mass effect as depicted by right sided midline shift and partial effacement of left lateral ventricle.
