Summary:

Description
  • Radiopaedia case ID: 71674
  • Image ID: 51658134
  • Image stack position: 16/25
  • Plane projection: Axial
  • Aux modality: T1 C+
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Contrast-enhanced MRI demonstrates a large cyst located at the left middle cranial fossa, isointense to CSF at all MRI pulse sequences, homogeneously hypointense on T1 weighted MR, and hyperintense on T2 Weighted MR. There is no restricted diffusion and no enhancement. Features are characteristic of an arachnoid cyst. The arachnoid cyst produces a mass effect on the left temporal lobe, which is hypoplastic and displaced posteriorly. The cyst promotes bone remodeling and enlarges the left temporal fossa, with bulging of the temporal bone.
