- Fig 1.
A 79-year-old man with type II diabetes presented with a painful right ear and pain during mastication. CT shows an increased distance of the TMJ (A, white arrow) and infiltration of the retrocondylar fat pad and surrounding fat planes (B, curved arrow). The contrast-enhanced T1-weighted MR imaging shows enhancement of the retrocondylar fat pad (C, broad arrow), with increased FDG accumulation on PET/MR imaging (D, arrowhead). The biopsy of the external ear canal was positive for P Aeruginosa.

A 76-year-old man without a medical history presented with a painful ear and otorrhea. CT shows an increased distance of the TMJ (A, white arrow), obliteration of subtemporal fat lines, and a retrocondylar fat pad sign (B. arrowhead), as well as osseous destruction of the mastoid (C, white curved arrow). Contrast-enhanced T1-weighted image 2 weeks after diagnosis demonstrates progression of NEO with an anterior, medial, and intracranial spreading pattern complicated by a thrombus in the left jugular vein (D, black arrow) with increased FDG accumulation on PET/MR imaging (E, asterisk). History revealed noncompliance with antibiotic treatment. Biopsy of the external ear canal was positive for P Aeruginosa.

Coronal illustration of the location of the fissures of Santorini and the foramen of Huschke. The fissures of Santorini extend through the osteocartilaginous or cartilaginous junctions of the EAC (arrows). The foramen of Huschke (arrowhead) is located anterior-inferior to the EAC and posterior-medial to the temporomandibular joint.

Temporal bone axial and sagittal views of patients with NEO with a persistent foramen of Huschke. The views show a subtle (1A and 1B), mild (2A and 2B), moderate (3A and 3B), and extensive dehiscence (4A and 4B) as indicated by the white arrows.
