“…The CFC can be of arachnoid or neuroepithelial origin, differentiated only at pathology. 9 However, most are not confirmed with histopathology as they do not require surgery. There are reports of association of CFC with seizures, attention-deficit hyperactivity disorder, migraine, and narcolepsy.…”

Focal-onset seizures can be caused by underlying brain lesions including focal lesions such as granulomas, low-grade neoplasms, vascular lesions, or neuronal migration disorders. Polymicrogyria is a congenital abnormality of cortical formation occurring during embryonic life. Choroidal fissure cysts are either arachnoid or neuroepithelial cysts arising at the choroidal fissure, and mostly they are incidental findings having no significant clinical implications. Coexistence of both of these can lead to dilemma in the management decisions. We present a case of focal-onset seizures with an unreported coexistence of polymicrogyria with choroidal fissure cyst.

“…They are most often seen in the posterior fossa and spine, and are often hyperintense on T1 and FLAIR due to proteinaceous contents. Finally, choroidal cysts, seen at the level of the choroidal fissure, can be arachnoid or neuroepithelial in nature . They will also be solitary, but otherwise can have a similar appearance as a dilated PVS.…”

“…Finally, choroidal cysts, seen at the level of the choroidal fissure, can be arachnoid or neuroepithelial in nature. 31 They will also be solitary, but otherwise can have a similar appearance as a dilated PVS. Although these benign cystic entities share many imaging features with dilated PVSs and are also usually seen incidentally, the key features in distinguishing them is based on their location and that they are usually solitary compared with PVSs which come in clusters.…”

Perivascular spaces (PVSs), also known as Virchow-Robin spaces, are pial-lined, fluid-filled structures found in characteristic locations throughout the brain. They can become abnormally enlarged or dilated and in rare cases can cause hydrocephalus. Dilated PVSs can pose a diagnostic dilemma for radiologists because of their varied appearance, sometimes mimicking more serious entities such as cystic neoplasms, including dysembryoplastic neuroepithelial tumor and multinodular and vacuolating neuronal tumor, or cystic infections including toxoplasmosis and neurocysticercosis. In addition, various pathologic processes, including cryptococcosis and chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids, can spread into the brain via PVSs, resulting in characteristic magnetic resonance imaging appearances. This review aims to describe the key imaging characteristics of normal and dilated PVSs, as well as cystic mimics and pathologic processes that directly involve PVSs.

“…Согласно патоморфологическим исследованиям, ликворосодержащие дивертикулы на уровне хориоидальной щели покрываются паутинной оболочкой либо фрагментами паутинной оболочки и компонентами нейроэпителиальной ткани [8,17,27]. Дивертикул всегда сопряжен с желудочковой системой мозга и обычно сообщается с ней [2,18].…”

“…Относительно лечения дивертикула желудочка мозга бытует мнение, что это заболевание зачастую протекает бессимптомно и редко требует хирургического лечения [17]. При симптомном течении болезни большинство клиницистов придерживаются хирургической тактики [18,34].…”

A clinical case of a 12 year-old girl with hydrocephalus complicated by rare condition, lateral ventricular diverticulum, is reported. Progression of the diverticulum was followed up according to MRI. The diverticulum of the lateral ventricular wall has emerged in the interval of 1 year (14 months have passed between the two MRI examinations) and spread towards the quadrigeminal cistern. In addition, compression of cerebellum, aqueductus cerebri Sylvii, and the fourth ventricle of the brain have emerged. A surgical treatment was suggested after the hydrocephalus had been initially revealed (when the diverticulum had not been formed yet); however, the child's parents refused the therapy. One year later, a series of epileptic seizures emerged, and MR scans showed a cystic neoplasm in the postcranial fossa above the cerebellum. The genesis of the cyst and its nature were unclear and additional invasive examination methods were required. MSCT ventriculography confirmed the diverticulum of the right lateral ventricle towards the quadrigeminal cistern.
