splenic disease

The spleen plays a vital role in our immune system, filtering the blood and storing white blood cells that help protect us from infection. However, various diseases and conditions can affect its function.

Causes of Splenic Disease

Several factors can cause splenic disease, including:

• Infections: Such as malaria, typhoid fever, and mononucleosis [1]
• Liver diseases: Like cirrhosis, which can lead to an enlarged spleen [2]
• Blood diseases: That cause abnormal blood cells, such as sickle cell disease [11]
• Problems with the lymph system: Which can lead to an accumulation of fluid in the spleen [12]

Symptoms of Splenic Disease

The symptoms of splenic disease can vary depending on the underlying condition. However, some common signs include:

• Pain behind the left ribs [4][7]
• Tenderness when touching the area [4][7]
• Enlargement of the spleen (splenomegaly) [1][2]

Complications of Splenic Disease

If left untreated or if the condition is severe, splenic disease can lead to complications such as:

• Rupture of the spleen: Which can be fatal if not treated promptly [10]
• Infections: Such as sepsis, which can be life-threatening [14]

Treatment Options

The treatment for splenic disease depends on the underlying condition. However, some common options include:

• Medications: To manage symptoms and prevent complications [8]
• Surgery: To remove the spleen (splenectomy) in severe cases or if the cause cannot be identified or treated [15]

Common Signs and Symptoms of Splenic Disease

An enlarged spleen, also known as splenomegaly, can cause a variety of symptoms, ranging from mild to severe. Here are some common signs and symptoms associated with splenic disease:

• Pain or fullness in the left upper belly: This is one of the most common symptoms of an enlarged spleen, which can spread to the left shoulder [1].
• Feeling full without eating or after eating a small amount: The spleen's enlargement can press on the stomach, causing discomfort and indigestion [5][15].
• Low red blood cells (anemia): An enlarged spleen can cause anemia due to its reduced ability to filter and store red blood cells [1].
• Frequent infections: A diseased or enlarged spleen can lead to a weakened immune system, making it harder for the body to fight off infections [3][13].
• Bleeding: In severe cases of splenic disease, bleeding can occur due to the spleen's inability to filter and store blood cells properly [10].

Other Possible Symptoms

In addition to these common symptoms, other possible signs of splenic disease include:

• Fatigue and weakness: These are common symptoms associated with anemia and reduced red blood cell production [2].
• Abdominal pain and diarrhea: In some cases, the spleen's enlargement can cause abdominal discomfort and diarrhea [9].
• Coughing and difficulty breathing: If the spleen is severely enlarged or diseased, it can put pressure on surrounding organs, leading to respiratory problems [9].

Seek Medical Attention

If you experience any of these symptoms, it's essential to seek medical attention promptly. A ruptured spleen, for example, requires emergency surgery and can be life-threatening if not treated immediately [10].

Diagnostic Tests for Splenic Disease

The diagnosis of splenic disease, including an enlarged spleen (splenomegaly), typically involves a combination of physical examination, laboratory tests, and imaging studies.

• Physical Examination: A healthcare provider will press on the abdomen to determine the size of the spleen and whether it's tender. This is usually done as part of a routine physical exam.
• Blood Tests: Blood tests, such as a complete blood count (CBC), can help identify underlying conditions that may be causing splenomegaly, such as anemia or liver disease.
• Imaging Studies: Imaging studies like ultrasound, CT scan, and MRI are used to determine the size of the spleen and whether it's crowding other organs. These tests can also help identify any abnormalities in blood flow through the spleen.

Specific Tests

Some specific tests that may be ordered by a doctor to confirm the diagnosis of splenic disease include:

• Ultrasound or CT scan: To determine the size of the spleen and whether it's crowding other organs.
• MRI: To trace blood flow through the spleen.
• Blood tests: Such as a complete blood count (CBC) to check for anemia, liver function, and other underlying conditions.

Treatment Options for Splenic Disease

Splenic disease can be treated with various medications, depending on the underlying cause and severity of the condition.

• Hydroxyurea: This is a first-line therapy for treating splenic sequestration in patients with sickle cell disease. It has been shown to be effective in around 40% of patients (Cervantes, 2011) [5].
• Ruxolitinib and Navitoclax: A combination of these two medications has been found to be twice as effective in reducing enlarged spleens in patients with myeloproliferative neoplasms (MPNs) (Dec 11, 2023) [6].
• Minocycline Chloride: This medication can be used to treat splenic abscesses. It involves instilling minocycline chloride into the splenic cyst (Shimanuki, 1996) [8].
• Amoxicillin: This antibiotic is sometimes prescribed to treat infections that may cause an enlarged spleen.
• Supportive Care: In some cases, treatment for splenic infarction may involve supportive care such as analgesics, hydration, and anti-emetics (Dec 11, 2023) [14].

Important Considerations

It's essential to note that the underlying disease process must be treated in addition to any medication. Patients with limited splenic function require increased vaccination and prophylactic antibiotics for procedures involving the respiratory tract (Management of splenomegaly involves treating the underlying disease process, 2023) [10].

The differential diagnosis of splenic diseases can be quite complex, given the various conditions that can affect the spleen. Here are some key points to consider:

• Infectious and inflammatory processes: These include conditions such as abscesses, infarcts, and hematoma [8]. The imaging features may vary depending on the underlying cause.
• Primary vascular and lymphoid neoplasms: This category includes conditions like splenic artery aneurysm, hemangiomas, and lymphomas [12].
• Metastatic disease: Splenic metastases can occur from various primary tumors, including breast, lung, and colon cancer [11].
• Vascular processes: Conditions such as splenic infarct, thrombosis, and varices can also be considered in the differential diagnosis.
• Systemic diseases: Certain systemic conditions like Gaucher disease, amyloidosis, and sickle cell anemia can affect the spleen.

To narrow down the list of differential diagnoses for splenic lesions, radiologists can consider characteristic imaging findings, including:

• The nature and degree of lesion contrast enhancement
• The presence or absence of calcifications
• The location and size of the lesion

Careful evaluation and consideration of these factors are essential to determine the underlying cause of splenomegaly.
