Background: Idiopathic pseudotumour (IP) is a non-specific, non-neoplastic, inflammatory process without identifiable local or systemic causes. IP in the head and neck region present diagnostic and management issues.Methodology: Retrospective case series and literature review. Results:We describe clinical history, examination, laboratory investigations and image findings of three patients, all males who presented with facial pain and ophthalmoplegia. Scans revealed lesions in the pterygopalatine fossa. The diagnosis of idiopathic pseudotumour was confirmed by histopathology. We discuss their treatment pathways and prognosis.Conclusions: Idiopathic pseudotumours in the head and neck region especially those involving anterior skull base are rare.Understanding their presentation and characteristics might help an unsuspecting otorhinolaryngologist in the diagnosis and treatment of these lesions.
