Abdominal Inflammatory Myofibroblastic Tumour Presenting as a Pancreatic Mass: A Case Report

An abdominal inflammatory myofibroblastic tumor (AIMT), is a rare benign composed of and other mesenchymal cells. It can affect the entire body, predominantly in children young adults. The diagnosis challenging considering wide clinical presentation often be mistaken for malignant tumors. We report case 46-year-old female patient, who presented with intermittent pain weight loss, an palpable mass. Abdominal ultrasound found well-defined 18 cm, rounded mass, solid cystic components. CT demonstrated well-defined, hypodense, retro gastric mass 20 thickened wall heterogenous enhancement. had contact pancreatic tail, transverse colon, spleen, left kidney pedicles, aorta, superior mesenteric vein, mesaraic trunk no invasion signs. was initially thought to cancer, but given large size, diagnoses like sarcoma, lymphoma, or hydatid cyst were suggested. Endoscopic 18/12 well-limited calcifications. content both mobile vegetations, visible Doppler flow. body tail pancreas, spleen hilum, upper pole hepatic pedicle behind, sign. After multidisciplinary team meeting, decision taken perform surgical resection resection, distal splenopancreatectomy, sigmoid colectomy. Pathological immunostaining results consistent pseudotumor. postoperative recovery uncomplicated. patient remains asymptomatic obvious signs metastasis recurrence. AIMT represents reel diagnostic challenge. Clinical symptoms are unspecific. Radiological endoscopic features Surgical management best therapeutic option. treated by surgery complete resection. suggested long-term follow-up local recurrence risk.
