[Invasive orbital aspergillosis: Rare but important differential diagnosis in the case of immunosuppression]

Invasive aspergillosis originating from the paranasal sinuses is a rare disease that is associated with high mortality rates. We report on a 77-year-old patient with myelodysplastic syndrome and progressive left-sided proptosis persisting for 5 days. Antibiotic therapy and endonasal orbital decompression yielded insufficient improvement. Only upon application of complementary antifungal therapy was remission observed. Rapid diagnosis and treatment are essential in order to prevent life-threatening complications.

Aspergillosis of the Petrous Apex and Meckel's Cave

Cranial cerebral aspergillosis is a rare entity in immunocompetent patients. Invasive disease involving the petrous apex and Meckel's cave has rarely been described. We present a case of localized invasive petrous apical and Meckel's cave disease in an immunocompetent patient who presented with hemicranial neuralgic pain.
