INTRAOSSEOUS HAEMANGIOMAS ON HYBRID IMAGING: A PICTORIAL REVIEW

Abstract

Osseous haemangiomas are benign skeletal tumours, usually identi ed as incidental ndings on different imaging modalities. Bone scan is the most frequent radionuclide procedure performed as metastatic workup in patients with various malignancies. Not every hotspot on a staging bone scan is malignant. Haemangiomas with variable degree of radiotracer uptake on technetium-99m (Tc-99m) bone scintigraphy may be falsely labelled as metastases in background of known malignancy. The addition of single-photon emission computed tomography computed tomography (SPECT-CT) enhances the specificity of bone scan which allows accurate detection and anatomical localisation of scintigraphic findings. We present a case series as pictorial review of osseous haemangiomas identi ed on Tc-99m methylene diphosphonate SPECT CT at our department.
