Late-onset-case of Familial Mediterranean fever (FMF)—exotic but rising differential diagnosis of “unclear abdominal illness” in Germany due to increasing migration over the past decade

The case underscores the importance of thorough history-taking and highlights the need to avoid unnecessary CT scans in similar settings. Awareness of FMF is crucial in nonendemic regions experiencing increased migration from high-incidence countries.
