Negative Bone Scintigraphy With Diffuse Osteoblastic Breast Carcinoma Metastases

Abstract

A patient with diffuse osteoblastic metastases from invasive lobular carcinoma of the breast is presented in whom radionuclide bone scan was negative for skeletal lesions. Skeletal metastases were documented by plain radiography, CT, MRI, and bone marrow biopsy. This case report points to the value of plain-film, CT, and MRI findings in situations of high clinical suspicion of metastatic disease despite a normal scintigraphy.
