D73.3 Abscess of spleen

Name of the Condition

• Abscess of spleen

Summary

An abscess of the spleen is a localized collection of pus within the spleen, typically resulting from infection. The spleen, an organ involved in filtering blood and supporting immune function, can develop an abscess when bacteria or other pathogens invade and form a contained infection. This condition may disrupt normal splenic function and require prompt medical attention.

Causes

Abscesses of the spleen are often caused by bacterial infections, which can spread to the spleen through the bloodstream (hematogenous spread) or from nearby infected tissues. Common pathogens include Staphylococcus aureus and Streptococcus species. Underlying conditions such as endocarditis, intra-abdominal infections, or immunosuppression may increase the risk of splenic abscess formation.

Risk Factors

• Bacterial infections (e.g., endocarditis, intra-abdominal sepsis)
• Immunocompromised states (e.g., HIV, chemotherapy)
• Recent abdominal trauma or surgery
• Chronic diseases (e.g., diabetes, liver cirrhosis)
• Intravenous drug use
• Presence of other abscesses or infections

Symptoms

• Fever and chills
• Left upper quadrant abdominal pain or tenderness
• Nausea or vomiting
• Fatigue or malaise
• Loss of appetite
• In severe cases, signs of sepsis (e.g., rapid heart rate, low blood pressure)

Diagnosis

Diagnosis involves a combination of clinical evaluation, imaging studies (e.g., ultrasound, CT scan, or MRI), and laboratory tests. Imaging helps identify the abscess and assess its size and location. Blood cultures may be performed to identify the causative organism, and additional tests (e.g., complete blood count) can evaluate for signs of infection or inflammation.

Treatment Options

Treatment typically includes antibiotics to target the underlying infection, often administered intravenously. For larger or persistent abscesses, drainage (via percutaneous or surgical methods) may be necessary to remove pus and promote healing. Supportive care, such as pain management and hydration, is also provided.

Prognosis and Follow-Up

With prompt treatment, the prognosis for splenic abscess is generally favorable, though outcomes depend on the size of the abscess, the patient’s overall health, and the speed of intervention. Follow-up imaging and clinical assessments are recommended to ensure resolution and monitor for recurrence.

Complications

• Rupture of the abscess, leading to peritonitis or sepsis
• Spread of infection to other organs
• Chronic infection or abscess recurrence
• Splenic dysfunction or damage requiring splenectomy

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk
• Manage chronic conditions (e.g., diabetes) effectively
• Seek prompt treatment for infections, especially those with systemic symptoms
• Avoid intravenous drug use to minimize infection exposure

When to Seek Professional Help

Seek immediate medical attention if you experience severe abdominal pain, high fever, or signs of sepsis (e.g., confusion, rapid breathing). Early evaluation is critical to prevent complications.

Tips for Medical Coders

Document the presence of a splenic abscess, including any associated symptoms, imaging findings, and treatment. Ensure the code D73.3 is used for confirmed cases, with supporting clinical documentation to validate the diagnosis. Note any procedures (e.g., drainage) or complications for accurate coding.
