Radiology ReviewOctober, 2012
You are called to the emergency department (ED) in reference to a patient who was sent there by radiology with a reported “brain mass” noted on imaging. During further investigation in the ED, the patient, who is in his 50s, stated that he has had headaches for the past several weeks; he consulted his primary care provider, who ordered outpatient MRI of the brain—the test that ultimately led to his arrival in the ED.
Since the MRI results were not immediately available for review, the ED staff obtained noncontrast CT of the head. The ED provider notes that it “looks like there is something there causing significant mass effect and shift.”
When you arrive to see the patient, you note that he is awake, alert, and oriented times three. His Glasgow Coma Scale score is 15, and his vitals signs are normal. He states he has a mild headache, rating it a 3 out of 10 on a pain scale.
His only other complaint is mild right-sided weakness, which he has noticed in the past week or so. Clinically, the strength in his right upper and lower extremities is good. His medical history is significant for prostate cancer and hypertension.
A single cut from the CT of his head is shown. What is your impression?
