Choroidal fissure cyst
Choroidal fissure cysts are benign incidental findings. Knowledge of these cysts are important as to not confuse these lesions with other more dire pathology such as cystic neoplasms or infectious cysts.
These lesions are identified by their characteristic location along the lateral aspect of the quadreminal plate cistern and homogeneous CT attenuation consistent with CSF. Occasionally, these cysts may exert small mass effect upon the adjacent brain parenchyma and may occasionally compress the adjacent hippocampus. No treatment is required.
