Choroid plexus papilloma is a rare but known cause of hydrocephalus among children. We report the case of an 8 month old girl who clinically was thought to have post-infective Hydrocephalus. Cranial CT however showed an associated intra-ventricular tumour which after surgical resection was reported as a Choroid plexus papilloma. This is the first time such a case is being diagnosed at our hospital and very few cases have been documented in literature from sub-Saharan Africa. This case highlights the available treatment and good prognosis that is possible with Choroid plexus papilloma. It also highlights the need for a high index of suspicion for less common causes of an enlarging head especially when the clinical picture is not typical as demonstrated in our patient. The seeming rarity of this disease in our environment may be partly due to the limited availability of CT scanners in many centres and the paucity of Neuroradiologist and Neurosurgeons in sub-Saharan Africa.
