Abstract:
Focal myositis is a rare disease defined by an isolated
inflammatory pseudotumour usually restricted to one
skeletal muscle. Approximately, 250 cases of focal myositis
have been described in the literature, and two recent large
cohorts have been used to help in the diagnosis. Isolated
gastrocnemius myositis, a rare immune-mediated condition,
is a diagnostic entity used by internal medicine clinician in
the gastrocnemius myalgia syndrome associated with
Crohn’s disease (CD). However, focal myositis and isolated
gastrocnemius myositis with Crohn's disease share clinical,
haematological, pathological, and radiological similarities.
We present a case of unilateral focal myositis of the
gastrocnemius muscle in a patient with no underlying
diseases, including Crohn’s disease. At clinical evaluation,
we encountered a challenge in differentiating between focal
myositis and the isolated gastrocnemius myositis of Crohn’s
due to similarities in clinical manifestation. We attempt to
clarify focal myositis and isolated gastrocnemius myositis
through our case report and a review of literature.
