MRI in hypertrophic mono- and polyneuropathies.

Different conditions that may lead to enlarged nerves or nerve roots include hereditary motor and sensory neuropathy (HMSN), neurofibromatosis (NF) type 1, chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and intraneural perineurioma. Differential diagnosis of hypertrophic mono- and polyradiculopathies remains challenging but is important because of different treatments and prognosis. Magnetic resonance imaging (MRI) can identify the hypertrophic nerve segments and guide a fascicular biopsy. A fascicular biopsy will often be necessary for precise diagnosis.

Uterus didelphys with obstructed hemivagina and renal agenesis: MRI findings.

Müllerian duct abnormalities (MDA) are developmental disorders leading to dysmorphism of the female genital tract. Currently the Buttram and Gibbons classification of these entities is widely used. We present a case of a young girl with uterus didelphys and ipsilateral renal agenesis.

Leiomyomatosis peritonealis disseminata in a 50-year-old woman: imaging findings.

Leiomyomatosis peritonealis disseminata (LPD)--or diffuse abdominal leiomyomatosis--is a very rare benign abdominal entity. Only a little more than 100 cases have been reported in the English literature since its first description in 1965. Middle aged female are typically affected and the clinical presentation is rather aspecific. The differential diagnosis between benign LPD and diffuse peritoneal carcinomatosis or abdominal disseminated malignancy represents the crucial diagnostic challenge that can only definitively be made through biopsy and histologic analysis. Multimodal imaging features (ultrasound, CT, MR and PET) of a case of LPD diagnosed in a 50-year-old female are presented with review the literature.
