 Patients with immune suppression may present with unusual infectious process of the head and neck. Sinonasal diseases are the most frequent and manifest in up to 60% of immunosuppressed adult patients. Early recognition and timely treatment of these potentially life-threatening disorders are essential. In this exhibit, we review and describe the CT/MR imaging characteristics together with signs and symptoms of the pathologic conditions in the head and neck in immunosuppressed patients.  The teaching points of this exhibit are; 1) to know the opportunistic head and neck infections in patients with immunosuppression; 2) to expose radiologists for relatively unusual lesions on CT/MR imaging in order to improve their diagnostic ability.  

Introduction Case presentation Each case will be presented with a review of clinical signs and symptoms, epidemiology, treatment as well as CT/MR imaging pearls with unique pathological insights. 1) Invasive aspergillosis 2) Aspergillus otomastoiditis 3) Malignant external otitis 4) Tuberculosis lymphadenitis 5) Chronic osteomyelitis of mandible 6) Gingival actinomycosis 7) Venous thrombosis 8) Others Summary
