Mesenteric inflammatory myofibroblastic tumor mimicking acute appendicitis: A case report

Area of Science:

• Gastroenterology
• Surgical Pathology
• Oncology

Background:

• Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm of intermediate biological potential.
• While commonly reported in pediatric patients, IMTs can occur in adults, often presenting diagnostic challenges.

Observation:

• This report details a case of small bowel mesenteric IMT in an adult female.
• The patient presented with recurrent symptoms mimicking acute appendicitis.

Findings:

• IMTs can exhibit diverse clinical and histopathological features, mimicking other abdominal pathologies.
• Prompt diagnosis necessitates a high index of suspicion, integrating imaging and histopathological examination.

Implications:

• Early and accurate diagnosis of mesenteric IMT is crucial for appropriate management.
• Surgical resection remains the primary treatment, with emerging roles for targeted therapies like tyrosine kinase inhibitors.
