Diffuse peritoneal leiomyomatosis

Radswiki et al.

Diffuse/disseminated peritoneal leiomyomatosis (DPL), also known as leiomyomatosis peritonealis disseminata, is an exceedingly rare benign disorder characterised by multiple vascular leiomyomas growing along the submesothelial tissues of the abdominopelvic peritoneum.

DPL is usually discovered incidentally in women of reproductive age.

Associations

A spectrum of features can be seen ranging from multiple solid subcentimetre nodules like those in peritoneal carcinomatosis to large solid masses on both ultrasound and CT. These masses may show homogeneous or heterogeneous attenuation with a variable enhancement pattern similar to that of uterine leiomyomas.

MRI

May show multiple masses with signal intensity similar to that of skeletal muscle and smooth muscle on both T1WI and T2WI. Homogeneous enhancement following the administration of contrast material.

The condition was first defined by H D Taubert et al in 1965 3.
