Clinical question: Please do CT guided bx of left parapharyngeal space mass. Compared to the prior CT scan a ring-enhancing lesion in the left parapharyngeal space measuring 24 x 15 mm on the prior exam is no longer ring-enhancing and currently measures 11 x 6 mm axial dimensions.
1.Since the prior exam the patient's left parapharyngeal space mass is significantly regressed in size. It's possible that this had represented an infection or a dilated parotid duct. As a result the procedure was aborted. If clinically appropriate a follow-up MRI of this area may be of further benefit to evaluate this.
