Small bowel leiomyosarcoma (LMS) is further rare, accounts for only 0.1%\u20133%\u2009fraction of these tumours. These cases can present as asymptomatic intra-abdominal mass, anaemia due to GI bleed or acute abdomen such as perforation peritonitis, intussusception and bowel ischaemia. Standard of care is surgical resection. Our case presented as large lobulated exophytic ileal LMS measuring 10.8\u00d711\u00d714.7\u2009cm involving multiple small bowel loops and abutting right iliac vessels and uterus. Patient\u2019s clinical course was complicated with COVID-19 positivity, deep vein thrombosis and pulmonary thromboembolism.
