Mesenteric Cyst: A Rare Entity

Abstract

Mesenteric cysts are rare entities that are challenging to diagnose and treat because of their variable presentation and histological characteristics. They have been majorly classified into six groups, out of which, the chylo-lymphatic type is the most common. Their etiology remains poorly understood but is usually linked to lymphatic pathologies. They are thin-walled cysts, present in the mesentery of the gastrointestinal tract. They can mimic multiple other cysts; hence, their timely diagnosis is of utmost importance. Imaging techniques aid in the preoperative diagnosis along with a thorough physical exam. The mainstay of treatment is surgical excision of the cyst, which is essential to prevent the recurrence of malignant transformation; the usual method of removal is laparoscopy. Alternative treatments are aspiration and marsupialization, which are only utilised for specific cases. The recurrence rate is usually low after total excision, but follow-ups are recommended for early detection of recurrence. This case study highlights the significance of prompt diagnosis and proper management of mesenteric cysts.
