No Longer an African Child’s Disease: The First Indonesian Case Report of Adeloye-Odeku Disease, A Rare Anterior Fontanelle Cyst

Abstract

Adeloye-Odeku disease was initially reported as an African congenital cyst in 1971, but this disease is now been documented worldwide. Adeloye-Odeku disease is classified as a congenital subgaleal inclusion dermoid cyst of the anterior fontanelle region. Mostly, this disease occurs in infants or children. This is the first case report of Adeloye-Odeku disease in Indonesia. The case report of a 5-month girl is presented with a lump that had developed since birth. The characteristic of lump was soft, non-tender, dome-shaped, and positive transillumination results. A computed tomography (CT) scan was carried out, with the result of a subgaleal dermoid inclusion cyst in the anterior fontanelle region. The anterior fontanelle appeared widened without intracranial expansion . Surgical excision of the cyst was performed under general anesthesia successfully. Histopathologic examination showed dermoid cysts without malignancy features. There were no complications reported when the patient attended the follow-up visit at the outpatient clinic. This is consistent with the existing literature on Adeloye-Odeku disease.
