Diagnostic MR imaging features of craniocerebral Aspergillosis of sino-nasal origin in immunocompetent patients

Abstract

Craniocerebral Aspergillosis of sinonasal origin has typical MR imaging features. These features include a mass lesion producing hypo-to-iso-intense signals on T1-weighted, extremely low signals (hypo-intense) on T2-weighted images, with bright homogenous enhancement on post-gadolinium T1-weighted imaging. These features in the clinical background may be helpful in early diagnosis and management of Aspergillosis of sino-nasal origin in immunocompetent hosts. Prospective clinical study is required to make firm clinical therapeutic recommendations.

Aspergillus Sphenoiditis Associated with an Artificial Bone Graft Used for Transsphenoidal Surgery

“…Gadolinium-enhanced image shows bright homogeneous enhancement suggesting solid nature of Aspergillus mass or ring enhancement suggesting cystic nature of pus. 15) Biopsy is essential for the final diagnosis.…”

Cerebral aspergillosis presenting as a mass lesion

“…These features include a mass lesion producing hypo-to-iso-intense signals on T1-weighted, extremely low signals (hypo-intense) in T2-weighted images, with bright homogenous enhancement in post-gadolinium T1-weighted imaging and disease processes in the nose and/or paranasal sinuses [11].…”

Common Who, Which, Why, How, What and When Questions of Invasive Fungal Infections

“…Magnetic resonance imaging (MRI) has no additional benefit compared to CT scanning for early diagnosis of invasive pulmonary Aspergillosis, but is the preferred imaging modality to ascertain and illustrate osseous, paranasal sinus lesions, or central nervous system disease [6][7][8].…”
