Abstract

11 patients with radio-opaque concrements in the sinus maxillaris underwent a preoperative computerized tomographic examination of the sinus maxillaris and the sinus concrements. 8 patients (72.7%) with the occurrence of radio-opaque concrements presented postoperative a histological and microbiological infection with aspergillus fumigatus. The CT-numbers of radio-opaque concrements in patients with aspergillus were 2802 +/- 302.4 HU (Hounsfield Unit). Concrements of patients without aspergillus infection (n = 3) had lower density (368.6 +/- 149.1 HU; p < 0.001). The root filling materials showed nearly the same CT-numbers in patients with aspergillus infection (2537 +/- 398.5 HU) and in patients without aspergillus infections (2544.3 +/- 460.6 HU). Density of root filling material was at the same level as density of radiopaque concrements in patients with aspergillus infections. According to CT-examinations a direct connection between root filling materials and aspergillus infection was noted. Therefore in patients with radio-opaque concrements computerized tomographic examination helps to determine the kind of sinus infection.

Aspergillosis

Aspergillosis is the name given to a wide variety of diseases caused by infection by fungi of the genus Aspergillus. Aspergillosis occurs in chronic or acute forms which are clinically very distinct. Most cases of acute aspergillosis occur in patients with severely compromised immune systems. Chronic colonization or infection can cause complications in people with underlying respiratory illnesses. Discover the latest research on aspergillosis here.
