Magnetic resonance imaging of leptomeningeal cyst with atypical presentation: Cough-induced headache

Leptomeningeal cysts, also known as growing skull fractures, are rare complications of head trauma. It is usually seen a few months posttrauma. These lesions are rare in adults, with over 90% resulting from fractures occurring in children under the age of 3 years. The children usually present with enlarging scalp mass, seizures, focal neurological deficit, and headache. In this case series, we are going to present the two cases of post traumatic leptomeningeal cysts in adults, presenting as cough-induced headache along with imaging description.
