ABSTRACT
Hydatidosis is a zoonosis due to the development of the larval form of Echinococcus granulosus in humans. This disease is very frequent in many countries of North Africa such as Morocco. The most frequent locations of hydatid cysts are the liver (75%) and the lungs (15.4%). Splenic hydatid cyst occurs in only 5.1% of cases. The diagnosis remains challenging and is made upon a hundle of clinical, radiological, biological, and histological arguments. In this paper, we report a case of spleen-preserving surgery for a splenic hydatid cyst to suggest the best management of these hydatid cysts and avoid recurrences.

Hepatosplenic schistosomiasis is a complex clinical condition caused by the complications of chronic infection with Schistosoma species that cause intestinal schistosomiasis. Hepatosplenic schistosomiasis derives from the fibrotic reaction stimulated around parasite eggs that are transported by the mesenteric circulation to the liver, causing periportal fibrosis. Portal hypertension and variceal gastrointestinal bleeding are major complications of hepatosplenic schistosomiasis. The clinical management of hepatosplenic schistosomiasis is not standardised and a parameter that could guide clinical decision making has not yet been identified. Transjugular intrahepatic portosystemic shunt (TIPS) appears promising for use in hepatosplenic schistosomiasis but is still reported in very few patients. In this Grand Round, we report one patient with hepatosplenic schistosomiasis treated with TIPS, which resulted in regression of oesophageal varices but had to be followed by splenectomy due to persisting severe splenomegaly and thrombocytopenia. We summarise the main challenges in the clinical management of this patient with hepatosplenic schistosomiasis, highlight results of a scoping review of the literature, and evaluate the use of of TIPS in patients with early hepatosplenic schistosomiasis, to improve the prognosis.

Hydatidosis is an endemic disease in certain areas in the world particularly in the Mediterranean, the Middle East, and South America, caused by a cestode known as Echinococcus granulosus. Humans are the accidental intermediate hosts. The liver and the lungs are the most commonly involved organ. If the parasite passes through the pulmonary capillary bed, the hydatid cyst may develop at any site in the body like bone, pancreas, brain, kidney, and orbit. Isolated spleen hydatid cyst is very rare. We hereby report one observation of isolated hydatid cyst of the spleen in a patient living in non-endemic area and without any potential risk.

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) and shunt surgery are established treatment options for portal hypertension, but have not been systematically evaluated in patients with portal hypertension due to hepatosplenic schistosomiasis (HSS), one of the neglected tropical diseases with major impact on morbidity and mortality in endemic areas. METHODS: In this retrospective case study, patients with chronic portal hypertension due to schistosomiasis treated with those therapeutic approaches in four tertiary referral hospitals in Germany and Italy between 2012 and 2020 were included. We have summarized pre-interventional clinical data, indication, technical aspects of the interventions and clinical outcome. FINDINGS: Overall, 13 patients with confirmed HSS were included. 11 patients received TIPS for primary or secondary prophylaxis of variceal bleeding due to advanced portal hypertension and failure of conservative management. In two patients with contraindications for TIPS or technically unsuccessful TIPS procedure, proximal splenorenal shunt surgery in combination with splenectomy was conducted. During follow-up (mean follow-up 23 months, cumulative follow-up time 31 patient years) no bleeding events were documented. In five patients, moderate and transient episodes of overt hepatic encephalopathy were observed. In one patient each, liver failure, portal vein thrombosis and catheter associated sepsis occurred after TIPS insertion. All complications were well manageable and had favorable outcomes. CONCLUSIONS: TIPS implantation and shunt surgery are safe and effective treatment options for patients with advanced HSS and sequelae of portal hypertension in experienced centers, but require careful patient selection.

BACKGROUND: Hepatosplenic schistosomiasis (HSS) is a disease caused by chronic infection with Schistosma spp. parasites residing in the mesenteric plexus; portal hypertension causing gastrointestinal bleeding is the most dangerous complication of this condition. HSS requires complex clinical management, but no specific guidelines exist. We aimed to provide a comprehensive picture of consolidated findings and knowledge gaps on the diagnosis and treatment of HSS. METHODOLOGY/PRINCIPAL FINDINGS: We reviewed relevant original publications including patients with HSS with no coinfections, published in the past 40 years, identified through MEDLINE and EMBASE databases. Treatment with praziquantel and HSS-associated pulmonary hypertension were not investigated. Of the included 60 publications, 13 focused on diagnostic aspects, 45 on therapeutic aspects, and 2 on both aspects. Results were summarized using effect direction plots. The most common diagnostic approaches to stratify patients based on the risk of variceal bleeding included the use of ultrasonography and platelet counts; on the contrary, evaluation and use of noninvasive tools to guide the choice of therapeutic interventions are lacking. Publications on therapeutic aspects included treatment with beta-blockers, local management of esophageal varices, surgical procedures, and transjugular intrahepatic portosystemic shunt. Overall, treatment approaches and measured outcomes were heterogeneous, and data on interventions for primary prevention of gastrointestinal bleeding and on the long-term follow-up after interventions were lacking. CONCLUSIONS: Most interventions have been developed on the basis of individual groups' experiences and almost never rigorously compared; furthermore, there is a lack of data regarding which parameters can guide the choice of intervention. These results highlight a dramatic need for the implementation of rigorous prospective studies with long-term follow-up in different settings to fill such fundamental gaps, still present for a disease affecting millions of patients worldwide.

In patients with Mansoni schistosomiasis, it is fundamental to evaluate the disease morbidity, which is reflected by the severity of periportal fibrosis (PPF) and parameters of portal hypertension, as analyzed by ultrasonography (US). This study aimed to evaluate the morbidity of schistosomiasis by hepatic and splenic point shear-wave elastography (pSWE) and relate this to US parameters. The PPF pattern, the diameter of the portal and splenic veins and the size of the spleen were evaluated by US. Then, liver and spleen pSWEs were assessed in 74 patients using the same equipment. As the PPF pattern progressed, the splenic pSWE values significantly increased. Significant correlations between splenic pSWE, the longitudinal and transverse lengths of the spleen and the diameters of the portal and splenic veins were observed. These findings, however, were not observed through hepatic pSWE. In conclusion, the splenic pSWE has the potential for assessing morbidity in schistosomiasis mansoni.

A 12-y-old spayed female Schipperke dog with a previous diagnosis of inflammatory bowel disease was presented with a 2-mo history of severe colitis. The patient's condition progressed to hepatopathy, pneumonia, and dermatitis following management with prednisolone and dexamethasone sodium phosphate. Colonic biopsies identified severe necrosuppurative colitis with free and intracellular parasitic zoites. Postmortem examination confirmed extensive chronic-active ulcerative colitis, severe acute necrotizing hepatitis and splenitis, interstitial pneumonia, ulcerative dermatitis, myelitis (bone marrow), and mild meningoencephalitis with variable numbers of intracellular and extracellular protozoal zoites. PCR on samples of fresh colon was positive for Neospora caninum. Immunohistochemistry identified N. caninum tachyzoites in sections of colon, and a single tissue cyst in sections of brain. Administration of immunosuppressive drugs may have allowed systemic dissemination of Neospora from the intestinal tract.

Occasionally, Plasmodium falciparum malaria is apparently precipitated by traumatic events (e.g., a landmine accident) or by noninfectious events (e.g., pregnancy). The authors reporting such cases often seem as baffled as many of their readers probably are. However, the case reports may contain important clues regarding malaria pathogenesis and immunity.

Elevated circulating endotoxin levels in the plasma of patients with advanced hepatosplenic schistosomiasis caused by Schistosoma mansoni have been reported, possibly caused by parasite egg-induced intestinal mucosal breaches facilitating bacterial access to the bloodstream. Neither endotoxin levels in people with S. mansoni but without hepatosplenic disease nor the impact of treatment on endotoxin levels have been described. We used a methodically optimized Limulus amebocyte lysate assay to measure plasma endotoxin in community-dwelling women from an S. mansoni-endemic area without clinical hepatosplenic disease. We found no difference in baseline mean plasma endotoxin levels between those with (n = 22) and without (n = 31) infection (1.001 versus 0.949 EU/mL, P = 0.61). Endotoxin levels did not change in schistosome-infected women after successful treatment (1.001 versus 1.093 EU/mL, P = 0.45) and were not correlated with circulating anodic antigen or stool egg burden. Our findings do not support the hypothesis that translocating eggs in S. mansoni infection introduce bacterial sources of endotoxin to the circulation.

Schistosomiasis, a neglected tropical disease, is a major cause of chronic morbidity and disability, and premature death. The hepatosplenic form of schistosomiasis is characterized by hepatosplenomegaly, liver fibrosis, portal hypertension, and esophageal varices, whose rupture may cause bleeding and death. We review currently available abdominal imaging modalities and describe their basic principles, strengths, weaknesses, and usefulness in the assessment of hepatosplenic schistosomiasis (HSS). Advanced imaging methods are presented that could be of interest for hepatosplenic schistosomiasis evaluation by yielding morphological, functional, and molecular parameters of disease progression. We also provide a comprehensive view of preclinical imaging studies and current research objectives such as parasite visualization in hosts, follow-up of the host's immune response, and development of noninvasive quantitative methods for liver fibrosis assessment.

PURPOSE: To identify the imaging manifestations of splenic involvement in babesiosis, a potentially fatal tick-borne zoonosis with multi-organ involvement. METHODS: In our single center HIPAA compliant IRB-approved study, we performed a retrospective search of the electronic medical record at our institution to identify all patients with known or suspected acute babesiosis from 2000 to 2017. We then reviewed all abdominal imaging of patients with confirmed disease to identify incidence and characteristics of splenic involvement. Splenomegaly was determined using a height- and gender-adjusted reference. RESULTS: After exclusions, 63 patients with a confirmed diagnosis of babesiosis and contemporaneous imaging of the spleen were included in the final cohort. Within this cohort, 56 (89%) had splenomegaly at a minimum and 13 had splenic infarcts. Splenic rupture was present in eight patients with three having a pseudoaneurysm. In 14 patients with follow-up imaging, the spleen subsequently diminished in size. One additional patient with ruptured spleen underwent emergency splenectomy prior to imaging. CONCLUSION: Although the literature suggests splenic involvement is a rare finding, acute parasitemia with babesiosis commonly affects the spleen. Recognition of this association can aid radiologists diagnosing splenic involvement in babesiosis and can lead to appropriate intervention in the minority with splenic hemorrhage.

We present a case report that demonstrates diagnostic and intraoperative challenges in the laparoscopic management of initially unrecognized splenic hydatid disease. A male patient, aged 44, was admitted to our department with a big unilocular splenic cyst, radiologically (ultrasonography, computed tomography) characterized as a simple cyst. Serological tests for anti-Echonococcus antibody were negative, and chests X-ray findings were unremarkable, so laparoscopic cyst fenestration with omentoplasty was planned. The intraoperative finding did not correspond to a simple splenic cyst. Hydatid daughter cysts were recognized after the careful opening of the cyst wall. The operation was completed without shifting to open procedures. Laparoscopic partial pericystectomy with omentoplasty is a safe and effective surgical procedure for the management of splenic hydatid disease.

Cystic echinococcosis (CE), also known as hydatid cyst, is a zoonosis caused by the tapeworm Echinococcus granulosus. It is a common health problem in many countries. This condition predominantly affects the liver and the lungs, and the spleen to a less extent (splenic hydatid cyst, SHD). Indeed, it is estimated that SHD occurs in less than 2% of abdominal CE and 0.5-8% of CE cases. Here, we present a case of a 44-year-old Chinese woman with primary giant SHD who experienced pain in the left hypochondrium for 10 days. A combination of abdominal ultrasonography and computed tomography (CT) were used for preoperative diagnosis. Laparoscopic splenectomy was performed without any complications, and albendazole (400 mg per day) was administered postoperatively for 3 months. At 3-, 6-, 12-, and 24-month follow-up, the patient remained symptoms free, and abdominal CT found no signs of recurrence. In addition to this case, we review the previous literature on SHD treated by laparoscopy and reveal that laparoscopic approach is safe and effective for SHD. Particularly, we show that laparoscopic splenectomy is feasible for giant cysts (> 10 cm) at high risk of rupture or compressing other vital structures.

Splenic abscess is a rare condition, which is often asymptomatic in the absence of comorbidity and is associated with high mortality rates. Given the importance of the differential diagnosis of patients who present to the emergency department with fever or septic shock, we report the case of a patient with amoebic splenic abscess who presented to our clinic with widespread skin rash and signs of septic shock following amoebic dysentery caused by Entamoeba histolytica, which is rarely reported in the literature.

BACKGROUND/AIMS: Hydatid disease remains an important global socioeconomic health problem, particularly in the endemic areas. Although half of the patients show no symptoms, hydatid cysts should be treated because of their fatal complications. The aim of this study is to present the long-term results of percutaneous treatment of hydatid disease using the Örmeci technique. MATERIALS AND METHODS: Forty-nine patients with 54 cystic lesions were diagnosed with hydatid disease. Twenty-seven of the 54 hydatid cysts located in the spleen were punctured with a 22-gauge Chiba needle through the parenchyma of the spleen under sonographic guidance as a one-step procedure. For every 1 cm of the long diameter of the cyst lesion, 3 cc of fluid from the cysts was aspirated. For each centimeter of the long diameter, 2 cc of pure alcohol (96%) and 1 cc of polidocanol (1%) were injected into the cysts. Five out of 27 patients did not participate in the follow-up. RESULTS: The 22 patients who were treated using the percutaneous Örmeci technique were followed up for a mean±SD (median) of 50.32±65.30 (26.00) months (minimum 4 and maximum 298 months). All patients except one were successfully treated. No deaths or major complications were noted. Seven patients experienced minor complications. CONCLUSION: Percutaneous treatment with the Örmeci technique is a safe, effective, cheap, and reliable method that does not interfere with splenic functions, and this outpatient procedure should be the method of choice for a surgery alternative.

Hydatid disease is caused by Echinococcus granulosus, which is endemic worldwide. This parasitic tapeworm can produce cysts in almost every organ of the body; however, the liver and lungs are the most frequently targeted. 37year-old multigravida woman with a 10-week pregnancy in whom multiple splenic and liver hydatid cysts were detected by ultrasound. All splenic and liver hydatid cysts were treated percutaneously under US guidance during the 14th week of pregnancy. The catheterization method was used in the treatment of all hydatid cysts. Alcohol was also used as scolicidal and sclerosing agent in all procedures. There were no major complications. A cystobiliary fistula developed in a hydatid cyst treated in the liver. A healthy baby was delivered vaginally at term.
