What does a 18 hounsfield unit low attenuation liver lesion mean?

An 18 Hounsfield unit low attenuation liver lesion typically indicates a region in the liver that has lower density compared to surrounding liver tissue, which may suggest the presence of a benign lesion such as a cyst, hemangioma, or focal nodular hyperplasia. However, it can also indicate potential malignancies or other pathologies depending on the clinical context and imaging characteristics. Further evaluation, such as additional imaging or a biopsy, may be necessary to determine the exact nature of the lesion. Always consult a healthcare professional for an accurate diagnosis and management plan.
