61-year-old male with metastatic malignant melanoma of the skin. There has further been interval decrease in size of the right sinonasal mass involving the inferior nasal terminate, right lateral nasal wall, and right maxillary sinus. For example, the maxillary sinus extension is decreased from 6 mm in transverse dimension on 7/9/2016 to 3-mm in transverse dimension on the current exam. The right lateral nasal wall thickness has gone from 10 mm to 4 mm. The lesion in the left lateral rectus muscle has also decreased in size from 10 mm to 7 mm in transverse dimension.There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. 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.
1. No evidence of intracranial metastases.2. Interval decreased size of the right sinonasal and left lateral rectus muscle metastases since 7/9/2016. Current examination is performed as a brain MRI. Subsequent follow-up MRI studies tailored to the sinuses/face may be helpful to assess for more subtle changes.
