Fulminant endogenous panophthalmitis caused by Clostridium septicum infection

We report an unusual case of fulminant endogenous Clostridium septicum panophthalmitis. A 74-year-old male patient presented with sudden amaurosis in the right eye, which in a few hours, evolved into an orbital cellulitis, endophthalmitis, anterior segment ischemia, and secondary perforation of the eye. A complete diagnostic study, which included cranial and orbital contrast-enhanced computed tomography scan, contrast-enhanced magnetic resonance imaging, blood cultures, and complete blood work, were performed. No causal agent was identified. Clostridium septicum infection caused fulminant gaseous panophthalmitis. Despite broad-spectrum antibiotic treatment, evisceration of the eyeball was necessary. The extension study showed a colon adenocarcinoma as the origin of the infection. Clostridium septicum panophthalmitis is a rare but aggressive orbital infection. This infection warrants the identification of a neoplastic process in the gastrointestinal tract in many cases not previously described.
