Cystadenoma

Last edited: 4/15/2026

Overview

Cystadenomas are benign epithelial tumors typically found in the ovaries and, less commonly, in the liver. They are characterized by the formation of multiple cysts lined by mucinous or serous epithelium 12.

Diagnosis

  • Imaging studies (CT, MRI) are crucial for identifying the presence and extent of cystadenomas 2.
  • Histopathological examination confirms the diagnosis, distinguishing between benign features and potential malignant transformation 2.
  • Specific to liver cystadenomas, presence of mesenchymal stroma and mural nodules may be noted 2.
  • Management

  • Surgical Excision: Complete surgical removal is the primary treatment, particularly for intrahepatic lesions where enucleation can be effective 3.
  • Ovarian Cystadenomas: Management often involves surgical intervention tailored to the size and location of the tumor 1.
  • Monitoring: Regular follow-up imaging is recommended post-surgery to monitor for recurrence 3.
  • Special Populations

  • Pregnancy: Specific management strategies for pregnant patients with cystadenomas are not detailed in the provided abstracts 1.
  • Elderly: Surgical risks may be higher; individualized assessment and minimally invasive techniques may be preferred 3.
  • Comorbidities: Patients with significant comorbidities may require tailored surgical approaches to minimize complications 3.
  • Key Recommendations

  • Complete Surgical Excision is mandatory for both ovarian and intrahepatic cystadenomas to prevent potential malignant transformation and recurrence (Evidence: Strong 23).
  • Enucleation can be effectively used for managing intrahepatic benign biliary cystadenomas, especially for centrally located large lesions (Evidence: Moderate 3).
  • Post-Surgical Monitoring with imaging is essential to detect recurrence early (Evidence: Expert opinion 3).
