22 year-old female with elevated INR and dilated pupils. Evaluate for brain hemorrhage, status post cardiac arrest. Focal hypodensity in the right cerebellar hemisphere is of unclear etiology. There is no evidence of intracranial hemorrhage, mass, or midline shift. Gray-white differentiation is preserved. The ventricles and basal cisterns are normal in size and configuration.The skull and other osseous structures are diffusely thickened and heterogeneous in appearance, which was noted on 2009 MRI. Maxillary sinuses, sphenoid sinuses, ethmoid air cells, and mastoid air cells are opacified bilaterally. Stranding in the soft tissues of the face is consistent with anasarca. Linear calcifications scattered throughout the scalp likely represent vascular calcifications.ET tube is noted.
1.No evidence of intracranial hemorrhage, hydrocephalus, mass effect or edema.2.Bilateral paranasal sinus and mastoid air cell opacification.3.Focal hypodensity in the right cerebellum is of unclear etiology or significance; MRI is recommended for further characterization if clinically indicated.4.Diffuse thickening and heterogeneity of osseous structures is nonspecific but may be related to systemic process such as renal osteodystrophy, hyperparathyroidism, or chronic severe anemia.
