BACKGROUND: Cerebrospinal fluid (CSF)-containing cysts at the level of the choroidal fissure are rare embryological entities infrequently described in the literature because of their benign nature. On the occasion of a case series, we present an overview of the literature and discuss anatomical and embryological location, imaging characteristics, presenting symptoms, and treatment indication of these lesions.
METHODS: We identified, in a retrospective study of a database with 81 patients harboring 86 supratentorial intracranial cysts, six patients with a CSF-containing cyst at the level of the choroidal fissure. In all cases, presenting symptoms were mild and the cysts were considered a fortuitous diagnosis. None of the patients was treated surgically, and the cysts remained stable at radiological follow-up. We performed a literature search for cerebral cysts and choroidal fissure cysts in particular.
RESULTS: Only one large study purely addressing choroidal fissure cysts was found in the literature.
CONCLUSIONS: CSF-containing cysts at the level of the choroidal fissure may be of the arachnoid or the neuroepithelial type, but pathological confirmation of a CSF-containing cyst at this specific location has never been published. Very infrequently they are symptomatic, and surgical treatment is hardly ever necessary.
