Summary:

Description
  • Radiopaedia case ID: 74306
  • Image ID: 52047344
  • Image stack position: 57/62
  • Plane projection: Coronal
  • Aux modality: T1 C+
  • Study findings: The patient refused surgery. An MRI exam was performed one year later (follow-up for same symptoms) showing:
  • Modality: MRI
  • System: Oncology
  • Findings: The MRI sequences demonstrate a well-defined extra-axial soft tissue mass (20x18x15 mm) at the left cerebellopontine angle with broad-based dural attachment, extending into the ipsilateral internal auditory canal with enlargement of the ipsilateral porus acusticus. It displays an intermediate signal intensity on T1WI, mild high signal intensity on T2WI/FLAIR with intense and homogeneous enhancement on postcontrast sequences with "dural tail sign". A mild mass effect is noted on the cisternal portion of the ipsilateral trigeminal nerve and middle cerebellar peduncle. Prominent subarachnoid space around the optic nerves with flattening of the posterior sclera bilaterally and partially empty sella turcica which may indicate idiopathic intracranial hypertension. The GE sequence was not performed.
