15-year-old male patient with history of right axillary abscess/edema status post I&D with drain placement. Evaluate for possible lymphatic malformation or soft tissue lesion. There are multiple prominent lymph nodes in the right axilla that are favored to be reactive. Small focus of T2 signal hyperintensity in the right axilla measures 1.6 x 1.2 cm (series 8 image 17) and may represent a small focus of residual collection versus a lymph node, as there is minimal adjacent edema and enhancement. There is no underlying soft tissue lesion or evidence of a vascular or lymphatic malformation.Small scattered left axillary lymph nodes noted.Incidental note is made of the renal cyst in the inferior pole of the left kidney.
1.Reactive right axillary lymph nodes and small focus of T2 signal hyperintensity in the right axilla may represent residual fluid collection versus a reactive lymph node.2.Left renal cyst.
