Bone scintigraphy may help differentiate bone sclerotic lesions from osteoblastic metastases in tuberous sclerosis patients with concomitant pulmonary adenocarcinoma.

Tuberous sclerosis (TS) is a multisystem disorder characterized by widespread hamartomas in multiple organs, including the skeleton. We present a case of bone involvement in a patient with TS and concomitant pulmonary adenocarcinoma. Bone scintigraphy is useful in distinguishing the TS bone lesions from osteoblastic metastases.
