A 40-year-old female with parasitic leiomyoma in the trocar insertion site of the abdominal wall with lymphatic dilatation.. A. Contrast-enhanced CT scan of the abdomen. Axial (left) and coronal (right) images show a 9.5 cm x 7.9 cm x 8.0 cm sized, well-demarcated bilobulated mass with heterogeneous enhancement in the left lower abdominal wall.. B. Contrast-enhanced T1 image (left) shows heterogeneous enhancement of the mass (arrows) excluding cystic portion. Axial T2 (right) weighted imaging shows dumbbell-shaped well-demarcated mass with internal cystic component (*) at the left lower abdomen.. C. Axial diffusion weighted imaging (left)/apparent diffusion coefficient (right) image shows multifocal diffusion restricted areas of the mass (arrows).. D. The gross specimen photograph shows a 7.5 cm x 7.0 cm x 6.5 cm sized, grayish, white mass with interlacing bundles of fibers.. E. Photomicrography shows lymphatic dilatation (*, left) (hematoxylin and eosin stain, x 20) and spindle cell with long and blunt-end (right) (hematoxylin and eosin stain, x 100).. F. In an immunohistochemical stain image (x 100) smooth muscle actin is positive.

It was located just below previous port insertion site in left lower abdominal wall through subcutaneous fat, left rectus abdominis muscle, and peritoneum (Fig. 1A). Contrast-enhanced T1-weighted imaging showed heterogeneous enhancement excluding cystic portion (Fig. 1B). Diffusion weighted image (DWI) and apparent diffusion coefficient image showed multifocal diffusion restricted areas (Fig. 1C). Surgical resection was done and it was diagnosed leiomyoma with lymphatic dilatation in pathologic study (Fig. 1D-F).
