Hepatosplenomegaly

Hepatosplenomegaly is defined as an abnormal enlargement of both the liver (hepatomegaly) and the spleen (splenomegaly). There are many causes of hepatosplenomegaly. Because hepatosplenomegaly has many possible causes, doctors may take a while to diagnose it. However, this is an important part of the process. Doctors need to find out the precise cause. This is because the treatment of the underlying cause is the first step in managing hepatosplenomegaly. For example, in Gaucher disease, hepatosplenomegaly (liver and spleen enlargement) can occur as the result of the liver not processing glucocerebroside properly. The buildup of this substance in body tissues can also lead to severe damage to the central nervous system in infants.

Hepatosplenomegaly causes

Infection

Many, many infections can produce a mild concurrent enlargement of the liver and spleen. This list is by no means exhaustive.

  • viral
  • EBV (infectious mononucleosis) (common)
  • AIDS with Mycobacterial avium complex infection
  • CMV
  • rubella
  • bacterial
  • tuberculosis (miliary)
  • subacute bacterial endocarditis
  • typhoid fever
  • brucellosis
  • syphilis
  • abscess
  • fungal

  • candidiasis
  • parasitic disease
  • malaria
  • schistosomiasis
  • hydatid disease
  • leishmaniasis (kala-azar)

Cancer

  • lymphoma
  • leukemia 1
  • multiple metastases: primaries: melanoma, pancreatic, breast, hepatic angiosarcoma
  • splenic metastases not usually seen unless advanced metastatic disease

Blood disorders

  • extramedullary hematopoiesis
  • thalassemia
  • sickle cell disease: normal/atrophic spleen more common
  • systemic mastocytosis
  • myelofibrosis
  • myeloproliferative disease
  • hemochromatosis
  • hemophagocytic lymphohistiocytosis
  • hemolytic anemias:
    • Hemoglobinopathies: Thalassaemia, sickle cell disease (eventually leads to splenic atrophy)
    • Red cell structure: Spherocytosis/elliptocytosis
    • Enzyme: G6PD deficiency, pyruvate kinase deficiency

Storage diseases/metabolic/infiltrative disorders

  • lysosomal storage disorders 2
  • Gaucher disease 3
  • mucopolysaccharidoses 4
  • Niemann-Pick disease
  • Wolman disease 1
  • alpha-mannosidosis 2
  • glycogen storage diseases
  • porphyria
  • amyloidosis
  • sarcoidosis
  • hypervitaminosis A

Connective tissue disorders

  • rheumatoid arthritis
  • Felty syndrome
  • juvenile rheumatoid arthritis
  • Still disease
  • systemic lupus erythematosus (SLE)

Others

  • cirrhosis (early)
  • chronic liver disease and portal hypertension
  • portal hypertension (non-cirrhotic)
  • Graves disease 5.

Hepatosplenomegaly symptoms

Hepatosplenomegaly symptoms depend on the underlying cause of hepatosplenomegaly. They often experience fatigue and pain in and around the affected organs.

Patients with severe cases of hepatosplenomegaly often suffer from pain in the upper-right quadrant of the abdomen. Vomiting and nausea, as well as jaundice and fever, are also common symptoms.

Patients can also experience abdominal swelling as well as dark-colored urine and stool.

Hepatosplenomegaly diagnosis

History in hepatosplenomegaly:

  • Presenting complaint
    • Abdominal swelling
  • History of presenting complaint
    • Abdominal pain
    • Bloating
    • Abnormal bruising/bleeding
    • Pruritus
    • Constitutional symptoms: weight loss, night sweats, fever
  • Past medical history
    • Previous EBV infection
  • Medications
    • Hepatotoxic medications
  • Family history
    • Malignancy
    • Connective tissue disease
    • Metabolic disorders
  • Social history
    • Travel history
    • Alcohol consumption
    • Smoking

Your doctor will examine you and ask questions such as:

  • Did you notice fullness or a lump in the abdomen?
  • What other symptoms do you have?
  • Is there any abdominal pain?
  • Is there any yellowing of the skin (jaundice)?
  • Is there any vomiting?
  • Is there any unusual-colored or pale-colored stools?
  • Has your urine appeared to be darker than usual (brownish)?
  • Have you had a fever?
  • What medicines are you taking including over-the-counter and herbal medicines?
  • How much alcohol do you drink?

Tests to determine the cause of hepatosplenomegaly vary, depending on the suspected cause, but may include:

  • Abdominal x-ray
  • Abdominal ultrasound (may be done to confirm the condition if your doctor thinks your liver feels enlarged during a physical exam)
  • CT scan of the abdomen
  • MRI scan of the abdomen
  • Routine blood tests – CBC, BUN, LFTs, CRP, ESR, HIV, TSH, autoimmune screen, including blood clotting tests
  • Plain chest X-ray
  • Stool cultures may be relevant. If infective diarrhea is syspected, you may require three samples on three separate days to increase the likelihood of catching the infection

Hepatosplenomegaly treatment

Hepatosplenomegaly treatment will largely depend on the cause of the hepatosplenomegaly.
