Sinusitis tends to occur in immunodeficient and immunosuppressed patients during periods of severe leukopenia. This group of patients includes those with primary immunodeficiency diseases, patients with leukemia receiving chemotherapy, and those undergoing bone marrow transplantation or kidney transplantation. The clinical and radiographic signs may be minimal or initially unimpressive. Sinusitis due to Aspergillus, Phycomycetes, or Pseudomonas may be fulminant and even fatal, requiring extensive surgical procedures for control.
