[Splenic hamartoma, severe thrombocytopenia, and macrocrania in a neonate: A case study]. / Hamartome splénique, thrombopénie sévère et macrocrânie chez un nouveau-né.

We report a case of splenic hamartoma associated with neonatal macrocrania diagnosed in a newborn. The diagnosis was made in the first 2 days of life upon the existence of an abdominal mass in the newborn infant. Abdominal ultrasound and abdominal computed tomography supported the diagnosis, but the histological study was inconclusive. The indication for surgery is still controversial. Through a literature review, the clinical, histological, and radiological aspects are discussed. The combination of neonatal hamartoma, thrombocytopenia, and macrocrania has never been reported.
