Autosplenectomy (AS) is a known complication of diseases such as sickle cell anemia, celiac disease, and inflammatory bowel disease. We report the first known case of AS due to paroxysmal nocturnal hemoglobinuria (PNH). A 24-year-old Caucasian male had evidence of hemolytic anemia at the age of 14 and was diagnosed with PNH at the age of 16. He had recurrent episodes of sepsis due to dialysis line infections from poor hygiene, and blood cultures had been positive for multiple organisms including Staphylococcus aureus , Enterococcus faecalis , and Streptococcus pneumoniae ...

Spleen abscess is a life-threatening disease. Treatment can be done by medical, radiological, or surgical methods. Here, we offer an innovative method of laparoscopic trocar-assisted percutaneous abscess drainage in the treatment of splenic abscess. Our patient, a 48-year-old male who had a kidney transplant 3 years previously, was admitted due to abdominal pain and fever. A-25-cm splenic abscess was detected, and ultrasonography-guided percu-taneous catheter 10F drainage was attempted. However, this attempt was not successful due to the high viscosity of the abscess content...

BACKGROUND AND STUDY AIMS: Upper gastrointestinal endoscopy (UGE) is currently recommended in cirrhotic patients to detect the presence of esophageal varices (EV). Spleen stiffness measurement (SSM) with FibroScan has been used for this purpose, showing variable sensitivity (S) and specificity (Sp). The aim of this study was to evaluate the capability of SSM to detect the presence and size of EV in cirrhotic patients in comparison to other noninvasive modalities. PATIENTS AND METHODS: Sixty-six patients with cirrhosis who had undergone UGE in the previous 6 months underwent SSM and liver stiffness measurement (LSM) using FibroScan...

There are varieties of surgical approaches reported for equine splenectomy and all of them were dealing with the most reachable situation of splenic hilus and easy handling of the spleen. The aim of this work was to establish the normal ultrasound parameters of spleen in donkeys (normal echogenicity, hilus situation, topographic location and correlation with neighboring organs) as a guide to select the best approach for total splenectomy in donkeys. Splenic ultrasound was carried out on six normal donkeys before experimental total splenectomy in the standing position...

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...

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...
