Mastoid and cranium computerized tomography at hospital admission with small
areas of probable mastoid cells discontinuity on the left side and important
amounts of discharge with some sparse gas focuses.

Computed tomography (CT) scans of the head and temporal bones revealed small areas of mastoid cell erosion on the left side; significant discharge with some gas focuses within the external ear canal, tympanic cavity, antrum, and left mastoid cells; these changes extended to the extracranial soft tissues, left face, and cervical region, reaching the skin, the external ear, and the parotid gland (Figure 1).
Galium-67 scintigraphy. Transversal (a), sagittal (b), and coronal (c) view
at the 21th day of hospitalization, showing an abnormal high uptake area in
the mastoid process of the left temporal bone. Transversal (d), sagittal
(e), and coronal (f) view, without increased uptake of the radiation marker,
3 months after discharge.

Three months after discharge, another Galium-67 scintigraphy did not show any abnormality in the area where previously there was increased uptake of the radiation marker due to the MOE (Figure 2).
