Introduction: Intramuscular hemangioma is an uncommon benign vascular lesion of skeletal muscle, and involvement of the pediatric abdominal wall is exceptional. Case presentation: A previously healthy 14-year-old boy presented with a 12-month history of a slowly enlarging painless right flank swelling. Examination showed a firm, non-pulsatile right lateral abdominal wall mass with normal overlying skin and normal laboratory tests. Contrast-enhanced computed tomography angiography demonstrated a 43 × 33 mm intramuscular lesion within the right external oblique muscle, with serpiginous enhancing channels, a dominant feeding artery from a lumbar branch of the abdominal aorta, and progressive delayed enhancement. Complete excision was performed through a transverse flank incision with ligation of the feeding vessel and complete resection of the lesion with a cuff of adjacent muscle. Histopathology confirmed a capillary-type intramuscular hemangioma with tumor-free margins. Recovery was uneventful, and the patient remained asymptomatic without clinical recurrence at 6 months. Conclusion: Intramuscular hemangioma should be considered in the differential diagnosis of a slowly enlarging pediatric abdominal wall mass. Complete excision with negative margins provides definitive treatment.
