Precocious true puberty secondary to a suprasellar arachnoid cyst: A case report and MR characteristics of common suprasellar cystic lesions

sThe incidence of suprasellar arachnoid cysts (SSACs), although rare in children, is increasing as a result of the advent of computed tomography (CT) and magnetic resonance imaging (MRI). However, the pathogenesis of precocious true puberty in the presence of SSACs is unclear. In the present paper, we report the case of an 11-year-old boy with precocious true puberty who exhibited a classic SSAC that was identified using CT and MRI imaging. In addition, we highlight the occurrence of SSACs in association with precocious true puberty and discussing the imaging differential diagnosis and the role of imaging technique in reaching the diagnosis.
