A 67-year-old woman with angiolipoma of the posterior mediastinum.. A. Chest radiograph demonstrates a right paravertebral bulging mass (arrows).. B. Unenhanced CT scan shows a lobulated right paravertebral mass (short arrows) with focal area (long slender arrow) of low attenuation (-31H).. C. Contrast-enhanced CT scan obtained at the same level as in B depicts an elongated highly enhanced (105-160 H) mass (short arrows) extending into the spinal canal (arrowheads). Due to the greater proportion of fatty tissue it contains, the focal area of low attenuation observed on noncontrast CT scan shows a mild degree of enhancement (long slender arrow).. D. Photograph of resected specimen shows a hypervascular lobulated mass with areas of yellowish fatty tissue (arrows).. E. Photomicrograph shows a combination of mature adipose tissue and multiple small blood vessels (H & E).

She had no neurological symptoms or signs but radiographs demonstrated a round mass with a well-defined margin in the right upper paraspinal area (Fig. 1A). CT scanning of the chest revealed a 2 x 2.5-cm-sized lobulated mass in the right paravertebral area (Figs. 1B and 1C). Further scanning, performed after the injection of intravenous contrast media, demonstrated a highly enhanced area of tubular appearance (105-160 H) extending to the spinal canal (Fig. 1C), and also an area of moderate enhancement (46.2 H).
