Question: I was diagnosed with stage 2A2 (node negative) squamous cervical cancer in December of 2012. I completed 23 external radiation treatments, 5 internal brachy therapy treatments, and 5 rounds of concurrent cisplatin in April of 2013. I had a hysterectomy in November of 2013. All pathology and CT scans have been negative for metastasis.
I follow up with my GynOnc every 6 months, and went in today for a CT with contrast of my abdomen and pelvis (it had been 6 months since my last one).

Today's CT noted my polycystic kidney disease, and diverticulosis. It also noted (and I'm quoting directly) from the CT report:
"The spleen, gallbladder, pancreas, and adrenal glands appear unremarkable except for the presence of a hypoattenuating focus splaying of the limbs of the left adrenal gland, centered at transaxial slice position minus 114.75, of +19.1 Hounsfield units in density and measuring 2.3 x 2.1 x 2.0 cm in size. This appears to been present (sic) on CT examinations dating back to 11/12/2010. On noncontrast CT preformed 10/202014, this particular focus demonstrates a mean density of +11 Hounsfield units. Please note the definitive modality to confirm that this represents a benign adenoma would be in-phase out-of-phase MRI examination.
Impressions:
Hypoattenuating focus involving the left adrenal as above as noted on CT examinations dating back to 11/12/2010


My question is could this be a cervical cancer metastasis to the adrenal, causing the increase in the HU numbers? This is the first mention made of HU density on a scan.....all previous scans noted a "benign adenoma on left adrenal" (or similar wording).

Is the increase in the Hounsfield units concerning?
Thank you for the follow-up....
