cystadenoma

What is Cystadenoma?

Cystadenoma is a type of benign epithelial tumor that can occur in various parts of the body, including the ovaries, pancreas, and other organs. It is characterized by the formation of a cyst or multiple cysts filled with fluid.

Types of Cystadenoma

There are several types of cystadenoma, including:

• Serous Cystadenoma: This type of cystadenoma is typically found in the ovaries and is composed of unilocular (or at times multilocular) cysts filled with clear watery fluid [3].
• Mucinous Cystadenoma: This type of cystadenoma is also found in the ovaries and is characterized by a multilocular cyst with smooth walls, containing fluid of various viscosity [8].

Characteristics

Cystadenomas can grow to varying sizes and may be filled with clear or mucous material. They are usually benign and have an excellent prognosis.

• Size: Cystadenomas can grow very large, sometimes appearing solid at first sight [11].
• Age: These types of cysts are most likely to appear towards the end of a woman's reproductive life or after it, specifically between the ages of 40 and 50 [11].

Imaging Appearance

On MRI, cystadenomas typically show features such as:

• Unilocular thin-walled adnexal cyst: This is the typical MR imaging appearance of serous cystadenoma [12].
• Beak sign: This may suggest an ovarian origin [12].

Common Signs and Symptoms of Cystadenoma

Cystadenoma, a type of ovarian cyst, can cause various symptoms depending on its size, location, and severity. Here are some common signs and symptoms associated with cystadenoma:

• Abdominal pain: A dull, heavy sensation or sharp, severe pain in the abdomen is a common symptom of cystadenoma [3][4].
• Bloating or swelling: Bloating or swelling in the abdomen can occur due to the growth of the cyst [5].
• Pain during bowel movements: Pain during bowel movements can be a symptom of cystadenoma, especially if the cyst is large and pressing on surrounding organs [5].
• Pelvic pain: Pelvic pain, which can range from a dull sensation to severe pain, is another common symptom of cystadenoma [7][8].
• Pain during sex: Pain during sex can occur due to the growth of the cyst and its pressure on surrounding tissues [7].
• Difficulty emptying bowels: Difficulty emptying bowels can be a symptom of cystadenoma, especially if the cyst is large and pressing on the rectum [5].

Other Possible Symptoms

In some cases, cystadenoma may not cause any symptoms at all. However, in more severe cases, the following symptoms may occur:

• Jaundice: Jaundice, a yellowing of the skin and eyes, can occur if the cyst is pressing on the bile ducts [2].
• Weight loss: Weight loss can be a symptom of cystadenoma, especially if the cyst is large and causing malabsorption of nutrients [2].

Important Note

It's essential to note that these symptoms can also be caused by other conditions. If you're experiencing any of these symptoms, it's crucial to consult with a healthcare provider for proper diagnosis and treatment.

Diagnostic Tests for Cystadenoma

Cystadenoma diagnosis relies on a combination of clinical evaluation, imaging studies, and histopathological examination. The following tests are used to diagnose cystadenoma:

• Imaging Techniques: Ultrasound, CT scans, and MRI are pivotal in identifying cystadenomas. These imaging modalities help ascertain the size, location, and characteristics of the tumour [2][3].
• Pelvic Exam: A pelvic exam is performed by a healthcare provider to feel inside the pelvis for any lumps or changes [4].
• Ultrasound: An ultrasound can pinpoint the location, size, and makeup of ovarian cysts. Abdominal ultrasound and vaginal ultrasound can evaluate ovarian cysts [7][15].
• CT Scan: A CT scan can identify the typical characteristics distinguishing SCAs from other cysts [4][6].
• MRI Scan: MRI scans also create cross-section pictures of

Treatment Options for Cystadenoma

Cystadenoma, a type of benign epithelial tumor, can be treated with various methods depending on its size, location, and symptoms. While surgery remains the primary treatment option, drug treatment is also being explored as an alternative or complementary approach.

• Targeted drugs: Treatment with targeted drugs might be helpful in managing cystadenoma. For example:
  • Bevacizumab (Avastin) may be given with chemotherapy to target cancer cells.
  • PARP inhibitor drugs such as olaparib (Lynparza), rucaparib (Rubraca), or niraparib (Zejula) may also be an option at some point.
  • The antibody-drug conjugate mirvetuximab soravtansine (Elahere) might be an option in some cases. [14][15]
• Pain relief: Narcotic analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) can be used for pain relief in patients with cystadenoma. [6]

It's essential to note that drug treatment is typically considered for symptomatic or large cystadenomas, while smaller ones may not require any intervention. Additionally, the effectiveness of these treatments may vary depending on individual cases.

Differential Diagnosis of Cystadenoma

Cystadenoma, a type of benign epithelial tumor, can be challenging to diagnose due to its similarity in appearance with other ovarian tumors. The differential diagnosis for cystadenoma includes:

• Mucinous cystic neoplasm: A type of ovarian tumor that is usually larger and multilocular than cystadenoma.
• Serous cystadenocarcinoma: A malignant form of cystadenoma, characterized by thick septa with solid components.
• Pseudocyst: A benign fluid-filled structure that can mimic the appearance of a cystadenoma on imaging studies.
• Focal pancreatitis: An inflammatory condition of the pancreas that can present as a cystic lesion similar to cystadenoma.
• Adenocarcinoma: A malignant tumor that can arise from the epithelial lining of the ovary, which may be confused with cystadenoma.

Key Features for Differential Diagnosis

To differentiate cystadenoma from other ovarian tumors, the following features are important:

• Size and location: Cystadenoma is typically smaller than mucinous cystic neoplasm and serous cystadenocarcinoma.
• Imaging characteristics: The presence of thick septa with solid components in serous cystadenocarcinoma can help differentiate it from cystadenoma.
• Histological features: The epithelial lining of cystadenoma is typically flat and cuboidal, whereas mucinous cystic neoplasm has a more complex histology.
