title: Hyperdense pelvic and inguinal lymph nodes.
abstract: This small series reports on the computed tomography appearance of hyperdense iliac, inguinal, and femoral lymph nodes in four cases of lymphoma and one case each of ovarian and breast carcinoma. The mean attenuation value of the lymph nodes was 93.8 Hounsfield units (HU), compared to 61 HU for adjacent muscle and 110.7 HU for blood vessels. A relatively homogeneous enhancement pattern was noted, which could not be directly related to hypervascularity, inflammation, or previous treatment with drugs or radiation.
