Inflammatory Myofibroblastic Tumor of Greater Omentum – A Rare Cause of Intra-abdominal Lump

Abstract

Inflammatory myofibroblastic tumors (IMTs) are uncommon mesenchymal tumors. These are seen more in children & young adults. These tumors can occur in any part of the body, like in lung, mesentery and omentum. Clinical presentation depends on the location of the tumor with associated low-grade fever, growth failure, malaise & weight loss. IMTs may be multicentric, have a high local recurrence rate. Usually benign, malignant transformation is very rare and may metastasize in rare cases. These lesions show wide variability in their histopathologic features like inflammatory infiltration, predominantly of plasmatocytes & lymphocytes and occasionally neutrophils & eosinophils. Owing to the rarity of these lesions, there are no specific imaging findings that distinguish IMTs from other mesenteric masses. Complete surgical excision is the treatment of choice. Local recurrences are high and re-excision is preferred.
