Skull base osteomyelitis arises as a complication of malignant external otitis, but it can be also due to middle ear and/or mastoid infection. Other causes can be infections of the paranasal sinuses or of the mandible or maxilla due to odontic caries. Generally, osteomyelitis involves elderly patients affected by diabetic immunodeficiency or microvascular disease. In this paper, we present 3 new cases of skull base osteomyelitis with atypical onset and evolution. The difficulties of diagnosis and details of the management are discussed.

AbstractLesions in the skull base may present difficulties in diagnosis primarily because the access needs to be invasive and one has to rely on imaging that may still be misleading. The case presented here illustrates this example in that the patient had abnormalities on computed tomography (CT) and magnetic resonance image (MRI) scans quite convincing of malignancy but which with time proved, essentially through clinical judgment, to be skull base osteomyelitis secondary to malignant external otitis (OME).

Extent Of Disease

ObjectiveThe prognosis of patients with malignant external otitis (MEO) depends on the extent of the inflammatory changes in the temporal bone and skull base. The efficacy of high-resolution computed tomography (HRCT) imaging in accurately assessing the extent of disease is compared with that of single-photon emission computed tomography/computed tomography (SPECT/CT) scan.Study DesignA clinical chart review was conducted with medical records and radiologic images.SettingTertiary care medical college hospital.Subjects and MethodsThis study involved patients with clinically diagnosed MEO who underwent both modalities of imaging of the skull base. Staging of the disease extent was compared between the imaging systems among patients. Symptom control and survival rates were analyzed with respect to the SPECT/CT staging of MEO.ResultsOut of 28 patients included in this study, 72% had SPECT/CT scans showing higher staging than the HRCT imaging. Four patients had mild uptake (stage 1), and 15 had disease confined to the mastoid/temporal bone, not reaching midline (stage 2). All patients in stages 1 and 2 were surviving with good symptom control. Five patients with petrous involvement reaching midline (stage 3) had persistent symptoms, and all 4 cases with SPECT/CT showing sphenoid involvement and crossing midline (stage 4) died within a year of diagnosis.ConclusionsSPECT/CT scan is more sensitive than HRCT imaging in detecting the extent of disease and is a better prognosticator for patients with MEO.

Middle Ear Infection

A 2-year-old previously well child presented to the emergency department with temperatures and lethargy. He was pale and looked unwell. He received a fluid bolus and was commenced on intravenous ceftriaxone. Pus was discharging from his left ear with postauricular swelling and erythema. Given clinical concerns, urgent neuroimaging was arranged.Question 1What does the CT scan of head show (figure 1)?Figure 1Enhanced CT showing external and middle ear infection with skull base osteomyelitis.Acute subdural collectionAcute mastoiditis secondary to sinusitisEnhanced cerebral lesionsMeningitis with abscess formationMiddle ear infection with skull base osteomyelitisA subsequent MRI scan was performed (figure 2).Figure 2MRI shows thrombus in left jugular vein, and MRA demonstrates occlusion of left internal carotid artery secondary to carotid sheath infection.Question 2What do these two images show?Left jugular vein dissection with subdural haematomaLeft jugular vein thrombus and carotid artery occlusionPosterior fossa tumourRight sided posterior communicating artery aneurysmSkull base abscessQuestion 3What is the most likely diagnosis?Acute mastoiditis secondary to chronic sinusitisCerebral tuberculosis (TB)Hereditary thrombophilia (protein S deficiency)Lemierre’s syndromeNon-accidental head trauma (NAI)Question 4What is the most commonly identified organism in this syndrome?Candida albicansFusobacterium necrophorumHaemophilus influenzaStaphylococcus aureusStreptococcus pyogenesAnswers can be found on page XX.
