Differential Diagnosis for Patient with History of Hep C and Abdominal Symptoms

The patient's symptoms of right upper quadrant (RUQ) and right lower quadrant (RLQ) fullness, nausea, early satiety, diarrhea, and a palpable liver on exam, in the context of a history of Hepatitis C, suggest a range of possible diagnoses. These can be categorized as follows:

• Single Most Likely Diagnosis

  • Cirrhosis with Portal Hypertension: Given the patient's history of Hepatitis C, a common progression is to cirrhosis, which can lead to portal hypertension. Symptoms such as abdominal fullness, nausea, and early satiety can be attributed to the increased pressure in the portal vein system, potentially causing splenomegaly and ascites, which would explain the palpable liver and abdominal discomfort.

• Other Likely Diagnoses

  • Hepatocellular Carcinoma (HCC): A known complication of chronic Hepatitis C infection is the development of HCC. A palpable liver could be indicative of a liver mass, and symptoms like weight loss, abdominal fullness, and nausea could be present.
  • Liver Fibrosis: Even if not fully cirrhotic, significant liver fibrosis from Hepatitis C could lead to a palpable liver and some degree of portal hypertension, explaining the patient's symptoms.
  • Gastroesophageal Reflux Disease (GERD) and Peptic Ulcer Disease: These conditions can cause nausea, early satiety, and abdominal discomfort but are less directly related to the palpable liver and Hepatitis C history.

• Do Not Miss Diagnoses

  • Spontaneous Bacterial Peritonitis (SBP): Although less common, SBP is a serious condition that can occur in patients with cirrhosis and ascites. It presents with abdominal pain, fever, and altered mental status, but early on, it might only cause non-specific symptoms like fullness and nausea.
  • Hepatic Encephalopathy: While primarily neurological, hepatic encephalopathy can have non-specific early symptoms that might overlap with the patient's presentation, such as nausea and altered mental status.
  • Budd-Chiari Syndrome: This rare condition, caused by hepatic vein thrombosis, can present with abdominal pain, nausea, and a palpable liver due to liver congestion.

• Rare Diagnoses

  • Primary Sclerosing Cholangitis (PSC): Although more commonly associated with inflammatory bowel disease, PSC can cause liver disease and might present with similar symptoms, including a palpable liver and abdominal discomfort.
  • Polycystic Liver Disease: This condition can cause a palpable liver due to numerous cysts but is less directly related to the patient's symptoms of fullness, nausea, and diarrhea unless causing significant liver enlargement or complications like cyst rupture.

Each of these diagnoses should be considered in the context of the patient's full medical history, physical examination, and appropriate diagnostic testing to determine the most likely cause of their symptoms.
