Pathological lesions in and around a joint can arise
from underlying dermis, subcutis, deep muscle, bone or
synovium. Clinical presentation can include joint pain,
joint swelling, palpable masses and mechanical restriction.
Whilst giant cell tumour of tendon sheath, pigmented
villonodular synovitis, synovial chondromatosis, lipoma
arborescens, juxta articular myxomas and inflammatory
arthritis are the better-known conditions of the joint.
Intra-articular nodular fasciitis, on the other hand, is less
well recognized both clinically and radiologically. It is
rarely seen in routine practice and is only described in case
reports in the literature. Due to the non-specific clinical
and radiological findings as well as the unfamiliarity with
the entity, the diagnosis of intra-articular nodular fasciitis
is usually clinched only after histological examination.
We present a case of intra-articular nodular fasciitis arising
in the knee joint which was not suspected clinically or
radiologically
