Capillary haemangioma of the greater omentum in a 5-month-old female infant: a case report

Capillary haemangiomas are frequent benign tumours in infancy. The authors report a case of capillary haemangioma of the greater omentum, discovered i n a child of 5 months of age and studied with US, CT and MRI. The localizat ion of such a lesion in the greater omentum is exceptional. Abdominal US re vealed a heterogeneous, multinodular intraperitoneal mass. Doppler study de monstrated hypervascularity of the lesion. CT localized the mass to the gre ater omentum. The mass was hypodense on the unenhanced scan and enhanced ma ssively after injection. The infant suffered a reaction to contrast medium during the CT. MRI demonstrated a mass which was hypointense on T1-weighted images and hyperintense on T2-weighted images. Laparotomy confirmed the lo cation of the mass within the greater omentum and allowed resection of the tumour.
