enchondroma

 [en″kon-dro´mah] (pl. enchondromas, enchondro´mata)
A benign growth of cartilage arising in the metaphysis of a bone. adj., adj enchondro´matous.

en·chon·dro·ma

(en'kon-drō'mă),
A benign cartilaginous growth starting within the medullary cavity of a bone originally formed from cartilage; enchondromas may distend the cortex, especially of small bones, and may be solitary or multiple (endochondromatosis).
[Mod. L. fr. G. en, in, + chondros, cartilage, + -oma, tumor]

enchondroma

A benign intramedullary tumour of hyaline cartilage that forms tumours in the medulla of metaphyseal bone and measures up to 5 cm, which accounts for 10% of all benign bone tumours. Half occur in the tubular bones of the hands/feet, especially fingers and toes.

Clinical findings
Most enchondromas of long bones (e.g., femur) are incidental findings in younger patients (age 15–40). Phalangeal enchodromas may predispose to fractures. 

Types
Solitary Enchondroma.
Multiple Enchondromatosis/Ollier disease.
Maffucci syndrome Multiple enchondromas and soft tissue haemangiomas.

The other findings like hydrocele, enchondroma, osteoma, ischiadic tubercle edema and dilation of the ureter may be interpreted to underline the value of MRI for detection of unexpected pathology of the soft tissues and even the bones in the groin and pelvic area that may account for one aspect of the groin pain (Leander, 2000).
