Giant Lipomatosis of the Sciatic Nerve: Unique Magnetic Resonance Imaging Findings

Lipomatosis of the nerve, also known as fibrolipomatous hamartoma, is characterized by the infiltration of the nerve by fibro-fatty tissue. The affected nerve becomes thicker, and it simulates a mass lesion. Lipomatosis usually affects the median nerve and lipomatosis of the sciatic nerve is extremely rare. Magnetic resonance imaging (MRI) is the key to diagnosis, and it is usually pathognomoni...

The giant seminal vesicle cyst: magnetic resonance imaging findings.

A 73-year-old man suffering from supra-pubic pain, dysuria and urinary retention for 3 months was slightly hypertensive, normoglycaemic, with normal renal biochemical parameters. In digital rectal examination prostate was slightly enlarged, but a cystic mass was palpable arising from the upper boarder of the prostate. He was examined by pelvic magnetic resonance imaging (MRI) with a preliminary...

Sciatic neuropathy: findings on magnetic resonance neurography

Injuries of the sciatic nerve are common causes of pain and limitation in the lower limbs. Due to its particular anatomy and its long course, the sciatic nerve is often involved in diseases of the pelvis or leg. In recent years, magnetic resonance neurography has become established as an important tool for the study of peripheral nerves and can be widely applied to the study of the sciatic nerv...

Giant pilomatrixoma: conventional and diffusion-weighted magnetic resonance imaging findings

ernous. A purely epidural hemangioma is a rare lesion, representing only 4% of epidural lesions, and the cavernous subtype is the most commonly found in this region. The lesion is located in the posterior region of the spine in up to 93% of cases and the dorsal spine is affected in 80% of cases. Epidural cavernous hemangioma is most commonly found in men (at a 2:1 ratio) aged over 40. Vertebral...
