ABSTRACT
PURPOSE:
Invasive aspergillosis usually affects immunocompromised patients. It carries a high risk of morbidity and mortality and usually has a nonspecific clinical presentation. Early diagnosis is essential in order to start effective treatment and improve clinical outcome. MATERIALS ANDMETHODS:
In a retrospective search of the PACS databases from two medical centers, we identified 9 patients with histologically proven cerebral aspergilloma. We systematically analyzed CT and MRI imaging findings to identify typical imaging appearances of cerebral aspergilloma.RESULTS:
CT did not show a typical appearance of the aspergillomas. In 100â% (9/9) there was a rim-attenuated diffusion restriction on MRI imaging. Multiple hypointense layers in the aspergillus wall, especially on the internal side, were detected in 100â% on T2-weighted imaging (9/9). Aspergillomas were T1-hypointense in 66â% of cases (6/9) and partly T1-hyperintense in 33â% (3/9). In 78â% (7/9) of cases, a rim-attenuated diffusion restriction was detected after contrast agent application.CONCLUSION:
Nine cases were identified. Whereas CT features were less typical, we observed the following imaging features on MRI A strong, rim-attenuated diffusion restriction (9/9); onion layer-like hypointense zones, in particular in the innermost part of the abscess wall on T2-weighted images (9/9). Enhancement of the lesion border was present in the majority of the cases (7/9). KEY POINTS · There are typical MRI imaging features of aspergillomas.. · However, these findings could be affected by the immune status of the patient.. · Swift identification of aspergilloma imaging patterns is essential to allow for adequate therapeutic decision making..
