15 year old male patient with history of juvenile nasopharyngeal angiofibroma status post resection. Post-contrast imaging is degraded by motion artifact. There has been interval partial resection of the left sphenoid sinus component and the left nasal cavity component of an enhancing mass consistent with the patient's known history of juvenile nasopharyngeal angiofibroma. There is residual infiltrative, enhancing tumor involving the left cavernous sinus, the left sphenoid bone, sella, clivus, and left pterygopalatine fossa extending into the left masticator space.There is no abnormal enhancement or diffusion-weighted abnormalities within the brain parenchyma. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are intact. There are post-surgical changes of a left antrostomy and middle turbinectomy with mucosal thickening of the left maxillary sinus.
Interval partial resection of the patient's known left-sided nasopharyngeal angiofibroma with residual infiltrative tumor as described above.
