We report a case of a patient with malignant otitis externa on the left side in which the 3 phase bone scan using MDP-Tc99m was used to confirm the clinical diagnosis and the extent of the complication. The bone scan showed absent blood flow in the left transverse and sigmoid venous sinuses, increased capillary permeability to the left temporal region and severelly increased bone uptake to the left mastoid region. This case demonstrates that the scintigraphic study can be useful to evaluate 2 of the main complications of malignant otitis externa, which are thrombosis of the transverse and sigmoid venous sinuses and mastoiditis.
