Fever and pain with neck movement. Brain: There is encephalomalacia and hemosiderin in the right parietal lobe, left occipital lobe, and left posterior cingulate gyrus. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no midline shift. There is mild diffuse cerebral volume loss with prominence of the ventricles and sulci. There is microcephaly.Face: There are secretions and mucosal thickening throughout the paranasal sinuses. There are numerous polypoid lesions in the nasal cavities. There appears to be thinning of the left frontal sinus posterior wall and there is a focal dehiscence in the right lateral sphenoid sinus wall. The orbital contents are unremarkable.
1. Sinonasal polyposis with widespread paranasal sinus secretions related to cystic fibrosis, with thinning of the left frontal sinus posterior wall and a focal dehiscence in the right lateral sphenoid sinus wall, but no evidence of intracranial collections. However, assessment for infectious processes is limited due to the lack of intravenous contrast.2. Encephalomalacia and hemosiderin in the right parietal lobe, left occipital lobe, and left posterior cingulate gyrus.3. Microcephaly.
