We report two cases of small bowel bleeding with distinct etiologies: Arteriovenous malformation (AVM) and gastrointestinal stromal tumor (GIST). In the first case, DCECT demonstrated a mass-like lesion with intense arterial-phase enhancement comparable to adjacent arteries and early venous drainage, strongly suggesting a vascular lesion.

In the second case, CT revealed a well-defined mass with relatively persistent enhancement and contrast extravasation, indicating active bleeding from a neoplastic lesion. Due to hemodynamic deterioration, emergency surgical resection was required, and the lesion was diagnosed as GIST.

Rarely, they demonstrate metastatic behavior despite benign histology, a condition known as benign metastasizing leiomyoma (BML). BML is exceedingly rare and can mimic malignancy, posing diagnostic challenges. We report a rare case of a 53-year-old woman with a history of hysterectomy for leiomyomas who presented with dyspnea and chest pain. Imaging revealed numerous bilateral pulmonary nodules, later confirmed to be smooth muscle tumors. After being lost to follow-up, she returned 2 years later with new breast and forearm masses. Imaging and biopsy confirmed metastatic smooth muscle tumors consistent with BML. Breast lesions mimicked benign cysts on ultrasound, underscoring the importance of clinical and histological correlation. The patient responded well to treatment with symptom improvement. This case highlights the rare phenomenon of BML metastasizing to multiple extrauterine sites, including the breast and soft tissues, locations infrequently reported. Imaging findings, particularly in the breast, can mimic benign lesions such as simple cysts, underscoring the need for biopsy and correlation with clinical history. BML should be considered in women with a history of uterine fibroids and indolent-appearing metastases without fludeoxyglucose uptake on positron emission tomography, computed tomography, and cystic appearance on ultrasound of breast lesions.
