48-year-old female with CF, status-post bilateral lung transplant, with worsening hypoxia, lethargy. Please evaluate for intracranial fungal infection or other potential etiologies of encephalopathy. Limited examination secondary to motion artifact and the use of portable scanner. Interval placement of nasoenteric tube and endotracheal tube.The ventricles, sulci, and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass effect, edema, midline shift, intra- or extra-axial fluid collection or acute hemorrhage. The calvaria and skull base are radiographically normal. The visualized paranasal sinuses again demonstrate partial opacification in the maxillary sinuses, ethmoid air cells, and hypoplastic frontal sinuses and sphenoid sinuses. This appears increased compared to prior CT examination. Opacification of the right mastoid air cells also appears increased compared to prior CT examination, although similar to prior MRI brain. The visualized left mastoid air cells are clear.Atherosclerotic calcification again identified along the distal left acute artery and the distal internal carotid arteries.
1. Limited examination secondary to motion artifact and the use of portable scanner. Within this limitation, there is no evidence of acute intracranial abnormality. 2. Increased opacification of the right mastoid air cells and paranasal sinuses.
