ABSTRACT

Diagnosis: Arachnoid Cyst

History: 27 year old man with bilateral hearing loss after surgical removal of a PE tube stuck behind his left TM. He underwent an MRI of the internal auditory canals for further follow up.

Findings: MRI for Internal Auditory Canal 1. Incidentally noted anterior left temporal fossa arachnoid cyst. 2. No evidence of retrocochlear or temporal bone-based pathology. 3. Sinusitis within both maxillary sinuses as well as fluid within the left mastoid air cells.

Ddx: Arachnoid cyst Epidermoid cyst Dermoid cyst Parasitic cyst Cystic glioma Chronic Hematoma

Dxhow: MRI

Exam: HEENT: Bilateral hearing loss, AS>AD. Neurologic: No other focal deficits or abnormal findings. Rest of exam was noncontributory.

No MeSH data available.


Cystic lesion anterior to the left temporal lobe, measuring about 3.0 x 3.0 x 3.5 cm, which follows signal characteristics of CSF on all sequences and is consistent with an arachnoid cyst.
