ReplyDeleteAn aspergillum is a liturgical instrument used to sprinkle holy water, and its shape resembles that of Aspergills under the microscope. The first image shows multiple ring-enhancing lesions with surrounding edema and mass effect. The second image shows abnormal soft tissue filling the ethmoidal air cell complex, nasal cavity, and maxillary sinus; the arrows show dural thickening and abnormal enhancement.
