“…On MRI, the lesion has been described as isointense to skeletal muscle on T1-weighted images and homogenous to heterogeneously hyperintense on T2-weighted sequences. The characteristic features described for angiomyomas include: a hypointense peripheral capsule with linear or branching internal hyperintensities on T2-weighted images and postcontrast diffuse homogenous enhancement, with one study describing a vessel leading up to the lesion in a majority of cases, as also seen in our case 3 8 9…”

Angiomyoma presenting as a painful subcutaneous mass: a diagnostic challenge

et al. 2014

Angiomyoma of the extremity is a notoriously elusive preoperative diagnosis, as the list of differentials for its described classic clinical features of a painful mobile subcutaneous mass is quite vast. Imaging features described for angiomyomas are far from being specific. On ultrasound, angiomyomas are mostly described as a well-defined solid mass lesion showing robust internal vascularity. On T2-weighted MRI they have been described as homogenous to heterogeneously hyperintense relative to skeletal muscle. We report a pathologically proven angiomyoma around the knee joint in a middle aged man, describe its clinical and imaging features, and outlay an approach in diagnosing this rare entity as a differential for painful subcutaneous mass lesions.

“…Cellular leiomyomas show relatively higher signal intensity on T2-weighted series and contrast enhancement following injection of contrast material intravenously (7). Similar to cellular leiomyomas, vascular leiomyomas also show hyperintense signal intensity on T2-weigthed series and contrast enhancement (8, 9). Degenerated leiomyomas have variable appearances on T2-weighted images and contrast-enhanced examination.…”

Symplastic Leiomyoma in the Suprarenal Inferior Vena Cava

et al. 2012

Leiomyomas are benign tumors of the soft tissue and may develop in any location where smooth muscle is present. Leiomyoma in the inferior vena cava is a rarely seen pathology, and symplastic leiomyoma is also a rare histological variant of leiomyoma. In this case, we present a rare histological variant of symplastic leiomyoma in the inferior vena cava (IVC). This is the first radiologically reported case of a symplastic leiomyoma of the IVC.

“…Hwang et al [11] reported that hyperintense areas on T2-weighted images corresponded with the presence of numerous vessels and smooth muscle, while areas isointense to skeletal muscle indicated tough fibrous tissue. Gupte [12]discussed ten cases of angioleiomyoma and found that typical lesions appeared homogeneous and were isointense to skeletal muscle on T1-weighted spin echo (SE) images. On T2-weighted fast spin echo (FSE), fat-saturated (FS), and short tau inversion recovery (STIR) images, the lesion was isointense to the surrounding fat and had an internal hyperintense area that was linear or branching in shape.…”

Case A 77-year-old woman was presented with a mass in the plantar side of left foot. Physical examinations revealed 30× 20-mm-sized hard mass with tenderness. Plane X-ray and computed tomography showed heterogenously calcified tumor that contacted with posterior tibial artery. Magnetic resonance imaging indicated spindle-shaped tumor in subcutis. That was isointense and hypointense on the T1-weighted image and hyperintense on the T2-weighted image. The tumor and its feeding artery, posterior tibial artery, were enhanced with gadolinium diethylene triamine pentaacetic acid. Surgical resection was performed, and the histology was characteristic of an angioleiomyoma. The patient had no symptom after surgery. No recurrence occurred 2 years after operation. Disccusion It is difficult to make a preoperative diagnosis of angioleiomyoma because it has no specific findings. MRI finding is useful but not specific. Our case had calcification with its feeding artery, so preoperative diagnosis could be done as vascular tumor. Complete resection is the curative treatment. Though, recurrent or malignant transformation cases were reported, thus careful observation is required.
