Idiopathic orbital inflammation with a rare parotid extension: a case report and review of literature

Objectiv e : Idiopathic orbital inflammation (IOI) is a benign inflammatory process usually confined to the orbit, with preponderance for extraorbital extension (EOE). We describe a case of IOI with possible extension to the parotid gland, a presentation yet to be reported in the literature.

Study design: This case report was an observational case study with the institution’s ethics committee adjudicating no requirement for ethical clearance for this case report.

Result: Case : A 38 year old man was referred from a psychiatric unit with a 9 year history of swelling of the right parotid region, with periorbital swelling and proptosis of the right eye. Patient was treated with steroid therapy and adjunct chemo-radiotherapy and was eventually lost to follow up. Diagnosis of IOI is based on clinical, imaging and histological examination. EOE of IOI, though rare has been reported with 41 cases reported to date. But an EOE to the parotid gland is yet to be reported. The significance of which is the possible addition of parotid gland scanning to all other previously known extraorbital sites, during an EOE survey, being part of IOI management.

Conclusion: None. We submit an IOI with possible EOE to the parotid gland to add to the broadening clinicopathological spectrum of IOI.

Conflict of interest: None declared.
