Main Article

Figure

Magnetic resonance imaging (MRI) of a patient with malignant otitis externa, France. Cross-sectional imaging demonstrates a central skull base osteomyelitis in patient’s temporal bone. A) T1-weighted imaging; B, E) 3-dimensional T1-weighted imaging with gadolinium enhancement and fat saturation; C, F, G) T2-weighted imaging; and CT with iodine enhancement (D). Single asterisks (*) indicate jugular bulb thrombosis (panels B, D); double asterisks (**) indicate deep-spaces cellulitis (panels A–C).

A) T1-weighted imaging; B, E) 3-dimensional T1-weighted imaging with gadolinium enhancement and fat saturation; C, F, G) T2-weighted imaging; and CT with iodine enhancement (D). Single asterisks (*) indicate jugular bulb thrombosis (panels B, D); double asterisks (**) indicate deep-spaces cellulitis (panels A–C). Arrowheads indicate parapharyngeal abscess at right (panels A–D); parapharyngeal abscess is also visible as a gray layer (panels E, G). The content of the abscess has an unusual “ink smudge” pattern with no signal in T2-weighted imaging, visible as a black layer (panels F, G). This pattern is consistent with a mycetoma surrounded by granulation tissue.
