@entity3 is an aggressive, destructive process most commonly affecting the immunocompromised host. Although frequently fatal, prognosis is related directly to early recognition and aggressive treatment. Various reports advocate computed tomography (CT) scanning as the study of choice in evalucating suspected invasive @entity364 , reserving magnetic resonance imaging (MRI) for select cases. Others report lack of correlation between CT and surgical or pathological findings. Our aim wasq to investigate the usefulness of CT and MR in the diagnosis of @entity3 . We retrospectively reviewed four cases of biopsy-proven invasive disease. Correlations between radiographic, endoscopic, and surgical findings were investigated. Rhizopus species were detected in three cases and mixed Mucor and Aspergillus species in another. Superimposed bacterial @entity1244 was confirmed in all cases. CT findings were nonspecific, revealing pansinusitis; no @entity79 or intracranial extension was noted. Mild @entity4550 was noted in one case. Anterior rhinoscopy revealed nonviable tissue in two @entity1 . Nasal endoscopy later confirmed tissue @entity63 in a third @entity1 , whereas a final @entity1 had normal findings on both exams. Nonspecific findings resulted in delay of diagnosis by 48-72 hours in two @entity1 with presumed bacterial @entity1244 . MR revealed intracranial extension in two @entity1 and better represented intraoperative findings. In conclusion, CT findings in @entity3 may be nonspecific and underestimate extent of disease. A high index of suspicion and early endoscopic examination with biopsy are mandatory for evaluation. MRI may better represent disease progression and should be considered early.
