title: [Maxillary sinus infection with emphysema of the head as a "red herring" in steroid associated colon perforation].
abstract: Steroid therapy increases the risk of bowel perforation. Bowel perforation may occur at any time of steroid therapy, but the first weeks appear to hold the greatest potential for perforation. However, clinical findings after perforation may be misleading under steroids, and peritonitis may be absent. It is known that bowel perforation can lead to subcutaneous emphysema at various sites. Thus, in any patient with emphysema, bowel perforation must be included in the differential diagnosis, especially in patients receiving steroids. Missing knowledge of this entity may lead to marked delay between onset of initial signs and diagnosis, and hence worsen the survival rate. In this report we present a case of chronic steroid use, where asymptomatic sigma perforation led to a generalized emphysema, which was initially attributed to a maxillary sinus infection due to Aspergillus and anaerobic bacteria.
