Mucinous Cystic Neoplasm of Mesentery: A Case Report

Abstract

Mucinous cystic neoplasms are very rare tumours. They may originate from ovaries, pancreas or other intra-abdominal sites but they rarely originate from the mesentery. They can be asymptomatic or present as an abdominal mass or abdominal pain. We present the case of a 28-year-old woman who presented with epigastric pain and cystic mass per abdomen with a diagnosis of mesenteric cyst made on further imaging studies. Subsequent excision and histopathological analysis demonstrated the cyst to be a mucinous tumour arising from the mesocolon. Mesenteric cyst must be considered as one of the differentials in abdominal cystic lesions.

Figure 1. CT image of the abdomen

The CT scan reveals a large, well defined multiloculated thin-walled cystic lesion with thin incomplete enhancing septae.

Figure 2. Intraoperative image

A large cystic lesion can be seen arising from the transverse mesocolon.

Figure 3. Gross specimen

The above images show a large, bluish-black globular mass with a smooth surface and intact capsule.

Figure 4. Cut specimen

The cut surface shows a multiloculated cyst exuding yellowish-green fluid.
