Sichelzellenanämie (abdominelle Manifestationen)
Computed
tomography of the spleen: how to interpret the hypodense lesion. Transverse contrast-enhanced CT images acquired during the portal venous phase. a A 43-year-old man with advanced sickle-cell disease. Note the irregular shape of the spleen, as well as the increased density of the splenic parenchyma, together with extensive calcifications as a consequence of constantly occurring micro-infarctions. b A 38-year-old man with sickle-cell disease exhibiting end-stage splenic involvement. Note the increased density, calcifications of the shrunken spleen
Imaging
findings of splenic emergencies: a pictorial review. Splenic sequestration. (a) CT features of ASSC. Contrast-enhanced axial CT image of a 26-year-old male with known sickle cell-thalassemia reveals lack of enhancement in spleen parenchyma (arrow). Retrograde filling of splenic vein (arrowhead) from the portal vein can be visualized. (b) Axial T2-weighted MRI demonstrates hypointense spleen (arrows) secondary to iron deposition. Splenic vein manifests with hyperintense appearance (arrowheads) due to slow flow resulting from retrograde venous filling

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
- splenomegaly
- 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
- autosplenectomy
- the slow, tortuous micro-circulation of the spleen renders it susceptible to infarction and subsequent functional asplenia
- 94% are asplenic by age 5
- radiological finding is of a small, calcified spleen
- splenic abscesses
Hepatobiliary
- hepatic iron deposition secondary to multiple transfusions
- hepatomegaly +/- coarsened echotexture with portal hypertension
- cholelithiasis +/- choledocholithiasis
- multiple liver abscesses
Renal
- kidneys are often large early in the disease, with variable echogenicity on ultrasound, but shrink with development of renal failure. Bilateral echogenic pyramids are frequently seen in sickle cell disease
- renal papillary necrosis
- renal vein thrombosis
Gastrointestinal tract
- approximately 40% patient may develop peptic ulcers due to reduced mucosal resistance and bowel ischemia
