A 25 yr old female first presented to the department of Medicine and subsequently referred to the department of Surgery, Christian Medical College, Vellore, India, in December 2018, with abdominal pain and distension for six months. Investigations revealed high serum ascites albumin gradient (SAAG), low protein massive ascites with negative tests for tuberculosis,  Budd-Chiari syndrome More Details and malignant ascites. Ascites persisted despite empirical anti-tuberculosis therapy for nine months.

Computed tomography revealed atypical features of loculated ascites scalloping the liver and mild omental thickening [Figure 1]. Further, magnetic resonance imaging in October 2019 revealed multiloculated cystic lesions filling the peritoneal cavity [Figure 2], further confirmed by laparoscopy [Figure 3] suggestive of cystic mesothelioma. Histopathology of the lesional biopsy with calretinin and D2-40 immunohistochemical staining confirmed cystic mesothelioma [Figure 4]. Upon three months follow-up, the patient had persistent ascites and was advised cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), which she is yet to have.
