Summary
Temporal lobe agenesis syndrome, a rare condition, is often linked to cerebrospinal fluid abnormalities. This report details an adult case with bilateral arachnoid cysts and normal neurological function.
Area of Science:
- Neurology
- Developmental Biology
- Radiology
Background:
- Temporal lobe agenesis syndrome is a rare congenital disorder.
- It is frequently associated with arachnoid cysts or cerebrospinal fluid collections.
- Arachnoid cysts typically occur unilaterally in the middle cranial fossa.
Observation:
- Bilateral middle cranial fossa arachnoid cysts are exceptionally rare, with only 9 prior reports.
- This study presents an adult case of bilateral arachnoid cysts and temporal lobe agenesis.
- The patient exhibited normal mental and neurological assessments.
Findings:
- Computed tomography (CT) and metrizamid CT cisternography confirmed the presence of bilateral cysts.
- The findings highlight a rare presentation of temporal lobe agenesis with bilateral arachnoid cysts.
- Despite the anatomical abnormalities, the patient maintained normal neurological function.
Implications:
- This case expands the understanding of the spectrum of temporal lobe agenesis syndrome.
- It suggests that significant structural brain abnormalities can coexist with normal neurological function.
- Further research into the pathogenesis and clinical manifestations of such rare conditions is warranted.
