    AbstractInflammatory pseudotumour (IPT) of the temporal bone is relatively rare in the head and neck, but it is important for clinicians to be aware of this emerging entity. A 39-year man presented with a protruding reddish mass over the left external ear. High-resolution Computed Tomography and Magnetic Resonance Imaging of temporal bone showed soft tissue collection in the left external ear, middle ear, and mastoid cavity with bony erosion. The patient first received modified radical mastoidectomy. Several surgeries were required for recurrences with eventual intracranial invasion within 2 years. The pathology showed chronic inflammation without malignancy, autoimmune or infectious pathologies. Based on the clinical manifestations, IPT was diagnosed. Finally, radiation therapy (RT) with 30 Gy was given. There was no recurrence following the RT course. Early recognition of IPT presenting as a recurrent and locally aggressive inflammatory lesion in the temporal bone is necessary to achieve favorable outcomes. Key Words: Inflammatory pseudotumour, Temporal bone, Radiation therapy.
