Multifocal Skeletal Tuberculosis Mimicking Metastatic Bone Disease: A Dilemma on Bone Scintigraphy
Objective: Multifocal skeletal tuberculosis is a rare condition in immunocompetent patient even in a tuberculosis endemic area. Diagnosis of such atypical cases is challenging to the physicians and treatment is delayed in majority of cases. The objective of this case report was to present a patient with tuberculosis with skeletal lesions.
Case report: A case of 60 years male was presented – with bony pain. His 99m Tc methylene diphosphonate (MDP) scan showed multiple foci of increased radiotracer resembling a metastatic bone disease. However, aspiration cytology and biopsy from the focal lesions and subsequent therapeutic response to anti-tubercular treatment indicated that the lesions were from tubercular infection.
Conclusion: Multiple bony lesions from tuberculosis may mimic metastatic lesions in bone scan.
