Abstract

Aim: To highlight atypical presentations of ROCM with orbital/intracranial extension without obvious nasal signs.

Methods: Retrospective series.

Results: 57 cases of ROCM with orbital involvement and a minimum of 3 month follow up were analysed. In 6/57 (11%) cases, endoscopic nasal examination was found to show healthy mucosa without any evidence of necrosis, ulceration or black eschar. Mucormycosis was confirmed histopathology and microbiology. Two had limited orbital disease, two had extensive orbital involvement necessitating exenteration and two had apical orbital disease; of which one progressed to a stage that needed exenteration. Life salvage was 100%. Imaging showed the

involvement of the Pterygopalatine fossa in all cases.

Conclusions: These cases highlight that ROCM does not always follow the traditional stepladder pattern of anatomical progression. ROCM may present with atypical features and in some cases, nasal endoscopy may yield false negative diagnostic findings.
