Symptomatic clinical presentation usually occurs in one of two ways: mass effect or rupture. Radiologically, dermoid cysts typically present as low density masses on computed tomography (CT) scan and are generally hyperintense on T1-weighted magnetic resonance imaging (MRI) sequences with variable signal on T2-weighted sequences. Case Description: We present the case of a 35-year-old female presented with symptoms of increased intracranial pressure. Radiological investigations showed a cystic posterior fossa tumor that was not only hyperdense on CT scans but also hypointense on MRI T1-weighted images. The patient underwent a total-gross resection of an extra-parenchymal posterior fossa tumor. Pathologic examination of the specimen concluded to dermoid cyst. Conclusion: Dermoid cyst of the posterior fossa is a benign lesion surgically treatable. Only an appropriate radiological diagnosis of this lesion would permit a well-targeted therapeutic approach.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/3d407fe1-7ae2-4dc9-bf7c-50dac43b9244/featured/hero-1782421051875.png","publishDate":"2018-05-07T00:00:00.000Z","doi":"10.4103/sni.sni_411_17","categories":["Unique Case Observations","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/3d407fe1-7ae2-4dc9-bf7c-50dac43b9244/pdf"}
