A rare neglected case of large leptomeningeal cyst: A case report

Abstract

Leptomeningeal cysts are enlarging skull fractures that occur near post-traumatic encephalomalacia. The term cyst is usually a misnomer as it is not only a cyst but also an extension of encephalomalacia. They commonly occur after severe head trauma during the first 3 years of life (especially infancy) and almost never after 8 years of life. Herewith, we present a case of a 7-year-old female patient who presented to our hospital with left-sided weakness since 2 years and painless swelling over the scalp since 3 years giving past history of head trauma. Plain radiography, computed tomography, and magnetic resonance imaging were performed which showed classical findings of leptomeningeal cyst. We will be discussing about the causes and radiological findings which help in diagnosis as well as treatment planning.
