5-year-old female with right labial vascular lesion. PELVIS:UTERUS, ADNEXA: No significant abnormality noted.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Within the subcutaneous soft tissues of the right labia, there is a 2.7 x 1.8 cm T1 hypointense, T2 hyperintense mass. The mass demonstrates avid fairly homogeneous arterial enhancement. Possible internal septations. It is supplied by mildly hypertrophied branches of the right pudendal artery. No early or enlarged draining vein is seen. OTHER: No significant abnormality noted.
Vascular mass within the right labia. Given the rapidity of filling in of the lesion on postcontrast imaging and the degree of vascularity demonstrated, a hemangioma is considered less likely as the appearance would be atypical. Among the differential considerations is a high flow AVM. While the mass appears to contain septations and otherwise appear fairly homogeneous on the current study, the sonographic appearance on the prior 5/26/15 ultrasound was much more heterogeneous. This raises concern for the possibility of a more rare, vascular tumor such as an angiomyxoma. Presurgical embolization is recommended prior to any future surgical intervention.
