In infants and children, the spleen is involved in many pathological processes, whether those processes are isolated or related to systemic diseases. Pathology of the pediatric spleen includes congenital anomalies, splenomegaly, trauma, focal lesions, infarction, and tumors. Ultrasonography (US) is a widely available, fast, noninvasive imaging technique to assess the size, shape, and position of the spleen, as well as to define splenic echotexture. US is capable of screening for splenic disorders without the risk of ionizing radiation; it is the initial imaging examination performed to evaluate suspected splenic pathology, providing clinicians with helpful decisional support...

Schistosoma mansoni causes morbidity in human beings, with the highest prevalence in rural sub-Saharan Africa. Prolonged S. mansoni infection with egg deposition in intestinal blood vessels leads to liver and spleen enlargement, and thus chronic morbidity. The objective of this study was to assess whether preschool-aged children develop severe S. mansoni -related morbidity. Parasitological, clinical, and ultrasonographic examinations were carried out in 916 preschool-aged children in five schistosomiasis-endemic districts (Bugiri, Buikwe, Jinja, Mayuge, and Namayingo) along the Lake Victoria shoreline in east-central Uganda...

Jin-Suk Kim, Ari Chong, Sun Moon Kim
More than 10% of the healthy population has one or more accessory spleens. An accessory spleen can be mistaken for a gastric subepithelial mass, and may not be differentiated by CT or endoscopic ultrasonography (EUS). A gastric subepithelial mass was detected on routine endoscopy in a 52-year-old man with a history of splenectomy 10 years previously for trauma. Subsequent EUS and CT located the subepithelial mass on the fourth layer of the stomach fundus. A definitive diagnosis was obtained by performing technetium-99m (99m Tc-)-labeled denatured red blood cell (RBC) scintigraphy...

Carin E Reust, Amy Williams
Recurrent abdominal pain (RAP) in children is defined as at least three episodes of pain that occur over at least three months and affect the child's ability to perform normal activities. RAP is most often considered functional (nonorganic) abdominal pain, but an organic cause is found in 5% to 10% of cases. Further workup is warranted in children who have RAP and fever, vomiting, blood in the stool, more than three alarm symptoms, or a history of urinary tract infections. Physical examination findings that should prompt further workup include weight loss or failure to grow; jaundice; costovertebral tenderness or back pain with lower extremity neurologic symptoms; liver, spleen, or kidney enlargement; an abdominal mass; or localized tenderness on abdominal examination...

Coeliac artery stenosis (CAS) is rarely of consequence owing to rich collateral supply from the superior mesenteric artery via the pancreatic head. Pancreaticoduodenectomy (PD) in CAS disrupts these collaterals, and places the liver, stomach and spleen at risk of ischaemia. A 56-year-old man presented with a 3-week history of obstructive jaundice. Computed tomography revealed an operable periampullary tumour with CAS due to compression by the median arcuate ligament with multiple collaterals in the pancreatic head and a prominent gastroduodenal artery (GDA)...
