Mesenteric cavernous hemangioma: Imaging-pathologic correlation

Mesenteric cavernous hemangioma: Imaging-pathologic correlation.

Résumé

A 50-year old female with no remarkable medical history consulted her doctor because of persistent epigastric pain. The clinical examination was unremarkable and laboratory tests were normal. Ultrasonography revealed a subumbilical, homogeneous, echogenic mass with an axial diameter of 5 cm. The mass had regular margins, posterior acoustic enhancement, and no visible vascularisation on colour Doppler imaging. Computed tomography (CT) of the abdomen and pelvis before and after administration of iodinated contrast material showed a tissue mass located in the mesentery with regular margins, no calcification, no communication with the bowel loops, and attenuation values of 70 HU before injection. After intravenous administration of iodinated contrast material, CT demonstrated discontinuous, peripheral nodes that enhanced centripetally, with a dynamic pattern of enhancement identical to that of the aorta and which persisted during the delayed phase. Multiple vessels were visible within the mass including a branch of the superior mesenteric artery, but there was no thrombosis or obstruction (Fig. 1). No enlarged lymph node was visible.
