Uzzo, MD, MBA, FACS, chair of the Department of Surgical Oncology at Fox Chase. Hypodense ( less dense) has to be relative to something else. They may also treat the cysts with surgery or medication.

Hepatic Lesions Deemed Too Small to Characterize: Prevalence and ... Small hepatic lesions (lesions 1 cm or less in diameter or deemed too small to characterize by the interpreting radiologist) noted on the initial scan were assessed at follow-up CT. Most are tiny cysts or other benign lesions. A too-small-to-characterize by CT criteria 7 mm. These are difficult to diagnose and difficult to biopsy percutaneously. . Subcentimeter liver lesions in women with breast cancer can be found in 29%, and if no obvious liver metastases are present, 93% to 97% of these subcentimeter liver lesions are benign [85]. A couples of tiny nodular hypodensities within the left kidney, too small to characterize, but most likely tiny cortical renal cysts. Effectiveness of MR Imaging in Characterizing Small Hepatic Lesions ...
