An opportune finding in suspected liver metastases.

Opportunistic mycobacterial infections are rare in immunocompetent patients. The authors describe a case of disseminated Mycobacterium avium complex disease in a previously healthy patient presenting with hepatosplenomegaly and non-specific symptoms which initially led to a diagnosis of metastatic carcinoma. After correct treatment she made a full recovery, with resolution of symptoms and the radiological findings.
