Manifestations of childhood illness in an adult patient. Leptomeningeal cyst: a case report and literature review

Abstract Background Traumatic leptomeningeal cyst or growing skull fracture is a rare disease that occurs primarily in childhood. The manifestations of leptomeningeal cysts in adults are often associated with injuries sustained in childhood. The rarity of the pathology, the peculiarities of clinical manifestations depending on the location of the lesion in the skull and surgical features require further research to improve outcomes of treatment. We touched upon the issue of epileptogenesis and its surgical solution, since the patient’s main complaints were epileptic seizures that did not respond to drug therapy. Case information A 21-year-old patient with epileptic seizures had an untreated progressive skull fracture that remained asymptomatic for about 20 years. Neurovisualization revealed secondary brain damage and brain hernia leading to gliosis. Electroencephalography revealed an epileptic discharge in the affected area. Conclusion Leptomeningeal cyst in adults is a rare occurrence that can be detected at any age. Surgical treatment with encephalolysis and glial removal has excellent results in treating epilepsy.
