Antecubital Fossa Solitary Osteochondroma with Associated Bicipitoradial Bursitis

Abstract EN

Antecubital fossa lesions are uncommon conditions that present to the orthopaedic clinic.

Furthermore, the radius bone is an uncommonly reported location for an osteochondroma, especially when presenting with a concurrent reactive bicipitoradial bursitis.

Osteochondromas are a type of developmental lesion rather than a true neoplasm.

They constitute up to 15% of all bone tumours and up to 50% of benign bone tumours.

They may occur as solitary or multiple lesions.

Multiple lesions are usually associated with a syndrome known as hereditary multiple exostoses (HME).

Malignant transformation is known to occur but is rare.

Bicipitoradial bursitis is a condition which can occur as primary or secondary (reactive) pathology.

In our case, the radius bone osteochondroma caused reactive bicipitoradial bursitis.

The differential diagnosis of such antecubital fossa masses is vast but may be narrowed down through a targeted history, stepwise radiological investigations, and histological confirmation.

Our aim is to ensure that orthopaedic clinicians keep a wide differential in mind when dealing with antecubital fossa mass lesions.
