[Single non-parasitic liver cysts]

Area of Science:

• Hepatology
• Radiology
• Gastroenterology

Context:

• Solitary non-parasitic hepatic cysts (NPHC) are rare, with autopsy incidence of 0.2-0.5% and imaging incidence of 2.5-4.6%.
• These cysts are more prevalent in females and can be congenital or acquired (post-traumatic, neoplastic, echinococcal).
• Diagnosis relies heavily on imaging modalities like ultrasound (USS), CT, and MRI.

Purpose:

• To outline the diagnostic procedures for hepatic cysts, including imaging and laboratory analyses.
• To discuss the differential diagnosis of hepatic cysts, considering various types and their specific markers.
• To review the therapeutic approaches for solitary non-parasitic hepatic cysts.

Summary:

• Imaging (USS, CT, MRI) is crucial for diagnosing hepatic cysts.
• Cystic fluid analysis, cystography, serologic tests, and tumor markers aid in diagnosis and differential diagnosis.
• Treatment options include percutaneous obliteration (e.g., alcohol injection) and surgical fenestration (deroofing), often performed laparoscopically.

Impact:

• Improved diagnostic accuracy for hepatic cysts through comprehensive imaging and fluid analysis.
• Facilitates appropriate management strategies for solitary non-parasitic hepatic cysts.
• Highlights the trend towards minimally invasive laparoscopic surgical techniques for hepatic cyst treatment.
