**Core Concept**
Hepatic adenoma is a benign, often hormonally driven liver tumor, most commonly associated with oral contraceptive (OC) use and prevalent in young, reproductive-age women. It is typically asymptomatic and detected incidentally on imaging.

**Why the Correct Answer is Right**
Hepatic adenomas are rare in older females and are most commonly seen in women of reproductive age, especially those using oral contraceptives. The condition is linked to estrogen exposure, not age. Thus, older females are not a typical demographic. The lesion is usually visible on ultrasound or CT, and may show a "cold" appearance on scintigraphy due to lack of perfusion, though this is not a defining feature.

**Why Each Wrong Option is Incorrect**
Option A: Benign lesion – This is true; hepatic adenomas are benign tumors, not malignant.
Option B: OCP use – True; oral contraceptive use is a major risk factor for hepatic adenoma.
Option D: Cold on isotopescan – True; adenomas often appear "cold" on scintigraphy due to poor blood supply and reduced tracer uptake.

**Clinical Pearl / High-Yield Fact**
Hepatic adenomas are most common in young women using oral contraceptives, and the risk increases with estrogen exposure. They are typically asymptomatic but can rupture or bleed, leading to acute liver failure—especially in patients with underlying liver disease or on high-dose OCPs.

✓ Correct Answer: C. Older females
