Differential Diagnosis for Right Cyst
- Single most likely diagnosis
- Ovarian cyst: This is the most likely diagnosis due to the high prevalence of ovarian cysts in women, and the fact that they can occur on either side, including the right side.
- Other Likely diagnoses
- Liver cyst: A liver cyst is a possible diagnosis, especially if the patient has a history of liver disease or has undergone imaging studies that show a cystic structure in the liver.
- Kidney cyst: A kidney cyst is another possible diagnosis, particularly if the patient has a history of kidney disease or has undergone imaging studies that show a cystic structure in the kidney.
- Mesenteric cyst: A mesenteric cyst is a less common but possible diagnosis, especially if the patient has a history of abdominal surgery or trauma.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Echinococcal cyst: Although rare, an echinococcal cyst (hydatid cyst) can be life-threatening if ruptured, and it's essential to consider this diagnosis, especially in patients with a history of travel to endemic areas.
- Appendiceal mucinous cystadenoma: This rare tumor can cause significant morbidity if not diagnosed and treated promptly.
- Rare diagnoses
- Choledochal cyst: A choledochal cyst is a rare congenital anomaly of the bile duct that can present as a cystic structure in the right upper quadrant.
- Retroperitoneal cyst: A retroperitoneal cyst is a rare diagnosis that can occur in the retroperitoneal space, which includes the area behind the peritoneum.
