INTRODUCTION: We describe the use of contrast-enhanced ultrasound (CEUS) in the diagnosis of delayed splenic vascular injury (DSVI) and active extravasation (DAE) during spleen injury follow-up. CEUS might be used instead of contrast-enhanced computed tomography (CECT) during spleen injury follow-up in order to reduce radiation exposure. OBJECTIVE: Assess diagnostic comparability between CEUS and CECT in the evaluation of DSVI and DAE during spleen injury follow-up...

Splenic cysts are a rare pathology, which can be classified as true (25%) or pseudocysts (75%). Total splenectomy has been the treatment of choice, particularly in recent times with the advent of the laparoscopic approach. However, as the spleen is an organ with multiple immunological functions, the laparoscopic partial splenectomy is an alternative, which is technically difficult but effective. We present a case of a 26-year-old woman with incidental evidence of a splenic cyst in an abdominal ultrasound scan...

INTRODUCTION: The spleen contains a reservoir of red blood cells that are mobilized into circulation when under physiological stress. Despite the spleen having an established role in compensation to acute hypoxia, no previous work has assessed the role of the spleen during ascent to high altitude. METHODS: Twelve participants completed 2 minutes of handgrip exercise at 30% of maximal voluntary contraction at 1045m, 3440m, and 4240m. In a subset of eight participants, an infusion of phenylephrine hydrochloride was administered at a dosage of 30 µg/l of predicted blood volume at each altitude...

The diagnosis of splenic infarction is rarely reported in pregnant women. Current incidence of splenic infarction, especially during infectious endocardites as well as diagnostic methods used are poorly specified in the literature. We here report the case of a 26-year old woman with no particular previous history or cardiovascular risk factor who, at the end 14 weeks of amenorrhea, presented to the Emergency Department with febrile syndrome evolving over 10 days and abdominal pain of recent onset at the level of the left hypochondre...

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...

INTRODUCTION: Digestive arterial aneurysms are rare. The splenic artery aneurysm (SA) is the most common visceral artery aneurysm (60% of cases). The origin of SA from the superior mesenteric artery (SMA) is an exceptional anatomical variation. The rupture of this aneurysm leads to death in 10 to 25% of cases. OBSERVATION: This is a 40-year-old adult presenting with abdominal pain associated with fever. An abdominal ultrasound shows a vascular mass projecting into the celiac region...

A boy aged 14 years had abdominal pain as the major manifestation, with elevated serum amylase and lipase. Abdominal ultrasound performed early after onset in another hospital showed enlargement of the pancreas and a reduction in echo. Magnetic resonance cholangiopancreatography (MRCP) showed pancreatic duct dilation and an unclear image of the head of the pancreas. Acute pancreatitis was considered. However, his symptoms were not relieved after fasting, fluid infusion, anti-acid therapy, and somatostatin therapy...

INTRODUCTION: Cystic lesions of the spleen are infrequent and usually diagnosed incidentally. These lesions are rare and their differential diagnosis is very wide. Splenic epithelial cysts are the most common type of primary splenic cyst (4%). Surgical treatment is indicated for cysts larger than 5 cm or symptomatic. Nowadays, spleen preserving surgery is the gold standard treatment considering the immunologic role of the spleen and the increased risk of post-splenectomy infections...

Splenic injuries are common emergencies in the setting of abdominal trauma, as the spleen is the second most frequently injured abdominal organ after the liver. The treatment of splenic injuries underwent a severe shift from operative to non-operative due to an increased awareness of the double physiological function, both immunological and hematological, of the spleen. This, in turn, led to an increased application of splenic preservation techniques. The non-operative approach has been strengthened through radiological imaging and interventional radiology...

RATIONALE: Hepatic epithelioid hemangioendothelioma (EHE) is a rare malignant vascular tumor of endothelial origin with a highly variable clinical presentation and natural history. Given its vascular origin, new therapies with inhibitors of vascular endothelial growth factor (VEGF) have been introduced in the treatment of these patients and have shown promising results. Few reports have described the role of F-Fluorodeoxyglucose positron emission tomography/contrast-enhanced computed tomography (F-FDG PET/CT) in the evaluation of this tumor after treatment with anti-angiogenic agents...

The spleen is considered a "forgotten organ" by most radiologists and paediatricians despite being affected in many clinical paediatric situations. While it is the organ most often affected in paediatric abdominal trauma, non-traumatic spleen disorders are less well known. The spleen is well visualised by any imaging technique: ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI); the former is used most often in children. Using imaging techniques to determine the features of splenic anomalies, both congenital and acquired, enables a correct diagnostic approach, avoids unnecessary surgical procedures or biopsies, and helps the clinician to prescribe appropriate treatment...

BACKGROUND: Post-operative pancreatic fistulae (POPF) remain a major contributor to morbidity and mortality following pancreatic resection. Evidence for preoperative prediction of POPF based on cross-sectional imaging has not been systemically reviewed. This review aimed to determine whether preoperative imaging modalities can accurately predict the development of POPF. METHODS: A systematic review of major reference databases was undertaken, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, up to May 2018...

OBJECTIVES: The clinical relevance of spontaneous portosystemic shunts detected by ultrasound is insufficiently investigated. The aim of this retrospective study was to assess the frequency and clinical relevance of spontaneous portosystemic shunts in patients with liver cirrhosis. METHODS: We evaluated portosystemic shunts, liver cirrhosis and spleen size by ultrasound in 982 patients with liver cirrhosis and correlated these with laboratory results, clinical data and the incidence of clinical endpoint deaths, liver transplantation and the development of HCC during the follow-up period (mean 1...

Splenectomy is indicated in selected children with haemolytic anaemia. Postoperatively, thrombocytosis occurs in at least 80% and is one of the factors implicated in the development of acute portal venous thrombosis after splenectomy in adults. A literature review shows that children are also at risk of this complication, but the incidence is low. The risk is greatest in those with particularly large spleens. Laparoscopic splenectomy does not reduce the risk of this complication. Early detection and anticoagulation usually leads to successful resolution of the thrombosis and can mitigate the risk of developing cavernous transformation of the portal vein and chronic portal hypertension...
