Focal nodular hyperplasia in a young female

Area of Science:

• Hepatology
• Radiology
• Oncology

Background:

• Oral contraceptive use is associated with benign liver lesions.
• Hepatic mass lesions require accurate diagnosis to guide management.

Observation:

• A 41-year-old woman on oral contraceptives presented with an asymptomatic hepatic mass.
• Abdominal ultrasound revealed a liver lesion, prompting further investigation.

Findings:

• Multimodality imaging including Doppler ultrasound, CT, and MRI suggested focal nodular hyperplasia.
• Ultrasound-guided liver biopsy confirmed the diagnosis, differentiating it from hepatic adenoma.

Implications:

• Accurate radiological assessment is crucial for diagnosing focal nodular hyperplasia.
• Distinguishing focal nodular hyperplasia from adenoma is important for clinical management.
• This case highlights the diagnostic approach to asymptomatic hepatic mass lesions.
