Answer for BIR CoW 31 July 2022
Fibrolipomatous hamartoma of median nerve
Radiographic features
•Ultrasound
A characteristic hypoechoic coaxial cabling encased by an echogenic substratum may be seen 3.
•MRI
MRI features are often pathognomonic and typically shows a coaxial cable-like appearance on axial images and a spaghetti-like appearance on coronal images
Discussion
•Also known as a neural fibrolipoma or lipomatosis of the nerve is a benign neoplasm of nerves, resulting from anomalous growth of fibroadipose tissue of the nerve sheath.
•seen more commonly in infants than in children and young adults. It usually presents as a slowly growing asymptomatic mass. Pain and paraesthesia can develop if associated with nerve compression or entrapment.
•Involves the median (80%), ulnar and or radial nerves and/or dorsum of the hand.
