摘要

We reported a rare case of hemorrhagic epidermoid cyst located in the anterior cranial fossa. A 66-year-old female presented with progressive nausea and vomiting for one month. Computed tomography revealed a mixed high and low density mass in the right lateral frontal basal region, with a few stippled calcifications at its inferior wall. Magnetic resonance imaging showed that the lesion was largely hyperintense on T1 weighted images and was of heterogeneously mixed high and low signal intensity on T2 weighted images. The lesion had a surrounding dark rim and exhibited curvilinear contrast enhancement in its medial margin. The patient underwent total surgical removal of the mass and did well during one year follow-up. Recognition of imaging findings facilitates appropriate preoperative differential diagnosis and is helpful to prevent leakage of cystic content during surgery.
