Abdominal manifestations of sickle cell disease
Abdominal manifestations of sickle cell disease (SCD) are wide and can involve many organs.
For a general discussion, please refer to sickle cell disease.
- splenic enlargement may occur transiently with the sequestration syndrome, where rapid pooling of blood occurs in the spleen, resulting in intravascular volume depletion, with potential for cardiovascular collapse.
- the slow, tortuous micro-circulation of the spleen renders it susceptible to infarction and subsequent functional asplenia
- 94% are asplenic by age 51
- radiological finding is of a small, calcified spleen
- splenic abscesses
- hepatic iron deposition secondary to multiple transfusions 1
- hepatomegaly + / - coarsened echotexture with portal hypertension.
- cholelithiasis + / - choledocholithiasis
- multiple liver abscesses
- kidneys are often large early in the disease, with variable echogenicity on ultrasound, but shrink with development of renal failure 1 . Bilateral echogenic pyramids are frequently seen in sickle cell disease.
- renal papillary necrosis
