This is the report from the CT Scan I had before my second parotidectomy:
Healthsouth Diagnostic Center of Greenville
Neck Soft Tissue CT:
Indication: Patient questionnaire indicates that he has a history of surgery on the right parotid gland about 10 years for a nonmalignant growth and he is now detecting another growth on the same side. This was noticed about 304 weeks ago and he denies and history of injury.
The patient received 100cc Isovue 300 intravenously for vascular enhancement purposes. Four millimeter contiguous transverse images extend from the skill base down to the superior mediastinum. Additional angled views were obtained through the deep face soft tissue to show them with less artifact from the patients dental work. A radiopaque marker was placed over the region the patient has detected a mass on the right side.
The portions of intracranial contents included on the exam are unremarkable. The deep face soft tissues and parapharyngeal spaces are symmetric and normal. A focus of slight increased density is demonstrated superficial to the right parotid gland and asymmetric from the left. It is rounded on images 84 & 85 (these are angled and show the lesion to better advantage than the original scan because of dental work artifact). It is more triangular shaped on image 87. It measures 1.5cm x 1.5cm on image 87 and is 1cm x 1cm on image 85. It is not as dense as the vessels on our first acquisition but is nearly isodense with those same vessels on the delayed angle views. It is more dense than the left parotid gland on our delayed views and nearly isodense on the first acquisition. These is no sign of cervical adenopathy. The remainder of the soft tissues show no additional findings with the submandibular glands being symmetric. The structures of the hypopharynx and airway are normal. Thyroid gland is remarkable for asymmetry with the inferior aspect of the left lobe being more prominent than the right and having two small zones of poor enhancement. I cannot rule out the possibility of cystic change or hypovascular nodules within the lobe. The superior mediastinum shows no abnormality. The lung apices are reviewed on lung window settings and show no lesions.
Delayed enhancing focus superficial to the right parotid gland where the patient has had prior surgery. A Venous structure is one consideration since it is showing delayed enhancement similar to the xxx (canít read). Other vascular lesion is another possibility but it is not enhanced on the arterial phase images. There is now infiltration in the fat around it to suggest that it is inflammatory and it is not certainly low density to suggest a fluid containing lesion. Neoplasm is not ruled out, however. I think some of the characteristics are atypical for malignancy.
There is no sign of adenopathy or other associated finding to suggest malignancy.

Thank you for referring this patient to Healthsouth Diagnostic Center.

The image on the left is a CT scan. Click on it to enlarge it. The circled area at the bottom is the area of the tumor. A CT Scan is an X-Ray. White is bone, grey is tissue.
The Scan on the right is an MRI scan taken after surgery. The dent on the right side of the ear at the bottom is where the tumor was removed. Unlike the CT scan, white is soft tissue. What appears to be the outline of the skull is really tissue (fat). The top of the head is on the left side of the image, jaw on right.
