Temporal bone osteomyelitis has been recognized for decades as a complication of otitis externa, specifically in elderly patients with diabetes. A much less prevalent form is skull base osteomyelitis. We report a 70-year-old man with diabetes who presented to our outpatient clinic with severe chronic daily complaints of headache. The headache was located frontoparietally and kept him awake at night. Imaging (nonenhanced computed tomography [CT], magnetic resonance imaging, and positron emission tomography/CT) showed a hypermetabolic mass on the right side of the skull base, in the middle ear, and in the mastoid process, with invasion and partial destruction of the surrounding elements of the petrous bone, the occipital bone, and the sphenoid bone on the right, with extension by way of the clivus into the apex of the left petrous bone. Diagnostic puncture revealed Streptococcus pneumoniae. The final diagnosis was severe daily headache due to central skull base osteomyelitis. Our case emphasizes the need for proper clinical and radiological investigation keeping the diagnosis of skull base osteomyelitis in mind with patients with diabetes or otherwise immunocompromised status who present with chronic daily headache and otalgia.

IgG4-related disease (IgG4-RD) is an emerging clinical disease entity characterized by tumefactive lesions at multiple sites with a dense lymphoplasmacytic infiltrate rich in IgG4+ plasma cells. Although almost any organ can be affected, IgG4-RD is most likely to involve the submandibular, lacrimal, or parotid glands in the head and neck region. However, skull base involvement presenting as otogenic skull base osteomyelitis (SBO) is rare. We encountered a 70-year-old male with IgG4-RD presenting primarily with severe otalgia and otorrhea. He had uncontrolled diabetes mellitus and showed clinical manifestations of otogenic SBO. Tissue immunostaining revealed typical features of increased IgG4-positive plasma cells, and hematological examination showed elevated serum IgG4 concentrations. Treatment with corticosteroids significantly improved well-being and partially resolved the lesion based on computed tomography (CT) scan.
