ABSTRACT
Hydatid cyst of the liver is a zoonosis caused by parasite Echinococcus granulosus, which remains highly prevalent in Morocco. Current medical imaging modalities, particularly ultrasonography (US) and computed tomography (CT), facilitate rapid and accurate diagnosis, enable effective treatment possibilities and allow for easy follow-up. Complications are typically dominated by infection and rupture, especially in the bile ducts, peritoneal cavity, and chest. Dissemination and development within vascular structures, especially the portal vein, are much less common. This underscores the significance of our case, which illustrates this rare complication of hydatid cyst of the liver.
ABSTRACT
Echinococcosis, a parasitic infection caused by Echinococcus tapeworms, can cause various symptoms depending on the location and size of the cysts. This article explores the complexities of echinococcosis, including its transmission cycle, clinical manifestations, diagnosis, and treatment approaches. The review highlights the challenges associated with diagnosing the different echinococcosis types, including cystic echinococcosis, alveolar echinococcosis, and polycystic echinococcosis. Each form of the disease necessitates a unique diagnostic approach that often combines serological tests, imaging techniques, and histological analysis. The article explores treatment options for each type of echinococcosis, including surgical resection, medication, and minimally invasive procedures such as puncture-aspiration-injection-reaspiration (PAIR). The article acknowledges current treatment methods' limitations and emphasises the need for further research into improved diagnostics, drug targets, and preventative measures. This review aims to provide a comprehensive overview of echinococcosis, encompassing its transmission, clinical presentation, diagnosis, and treatment modalities. By outlining the complexities of the disease and highlighting areas for future research, the article hopes to contribute to improved disease management and control. Key findings of the review include the identification of significant diagnostic challenges in differentiating between cystic, alveolar, and polycystic echinococcosis, the varying efficacy of treatment modalities such as surgical resection and PAIR, and the urgent need for further research into enhanced diagnostic methods, novel drug targets, and effective preventative strategies.
ABSTRACT
Introduction and importance: Hydatid cyst disease is a zoonotic disease caused by Echinococcus granulosus and is recognized as a significant health issue in many countries, particularly Mediterranean countries. Hydatid cysts in the musculoskeletal system are rare, with only a few reported cases. These usually occur as secondary cysts resulting from the hematogenous dissemination from primary sites. Case presentation: This paper reports a case of a 77-year-old man with a mass in his thigh that had been increasing dramatically in size for 4 months with no signs of local inflammation, fever, or any other symptoms. Findings from an MRI were consistent with a large abscess, so a true-cut biopsy was taken before referral. A pathological study after surgery revealed the lesion was a hydatid cyst, and a previously performed biopsy caused a rupture of the cyst. Clinical discussion: Misdiagnosing hydatid cysts, especially in non-usual areas, may lead to an unwelcome biopsy and consequences. Conclusion: This case report highlights the importance of considering hydatid cysts when encountering any enlarging mass, regardless of its location or rate of growth.
ABSTRACT
Isolated primary diaphragmatic hydatid disease (HD) occurs in approximately 1% of adult cases. However, this unique presentation of a pediatric diaphragmatic cystic mass has not been previously described in the literature. This study reports a rare case of a 12-year-old girl who was diagnosed with a diaphragmatic hydatid cyst. Surgical exploration via subcostal incision revealed an isolated cyst, free from the thoracic and abdominal viscera. Cystotomy, removal of daughter cysts, and excision of the pericyst cavity were performed, followed by diaphragmatic repair. Histopathological examination confirmed the diagnosis. The postoperative course was uneventful, and the patient completed an 8-week mebendazole regimen with no recurrence at 3 months' follow-up. This paper recommends including HD in the differential diagnosis for pediatric patients presenting with diaphragmatic lesions, particularly in regions endemic for echinococcosis.
ABSTRACT
Echinococcosis, caused by Echinococcus spp., often affects the lungs and liver, and spinal involvement is rare. Echinococcus multilocularis is prevalent in Japan, particularly in Hokkaido. We herein report a rare case of spinal echinococcosis in a 31-year-old woman who was diagnosed in Tokyo. Spinal echinococcosis is uncommon and often leads to misdiagnoses. The patient likely contracted the disease via contaminated fresh produce transported from an endemic region. This study emphasizes the diagnostic challenges of spinal echinococcosis in non-endemic regions and highlights the public health concerns related to the spread of infections in non-endemic areas.
ABSTRACT
There is increasing evidence that the secretory/excretory antigens of the larval stage of Echinococcus granulosus can induce both anticancer and oncogenic effects between parasite-derived metabolites and various cancer cells. The dual role of miR-145 as either a tumor suppressor or oncogene has already been reported in cancer. However, the mechanism by which miR-145 induces apoptosis in lung cancer cells treated with hydatid cyst fluid (HCF) remains unclear. The fertile HCF was obtained from sheep, purified and lyophilized. H1299 human lung cancer cells were then cultured into two groups: HCF-treated H1299 lung cancer cells and untreated H1299 cancer cells as control cells. Cell viability was assessed using MTT assay to evaluate the effects of HCF on the H1299 cells. Caspase-3 activity was assessed by fluorometric assay. In addition, mRNA expression levels of VGEF, vimentin, caspase-3, miRNA-145, Bax and Bcl-2 genes were quantified by real-time PCR. A scratch test was also performed to assess the effects of HCF on cell migration. The MTT assay revealed that the growth of H1299 cells increased when treated with 60 µg/mL of fertile HCF for 24 hours. The fold change of caspase-3, miRNA-145, Bax/Bcl-2 ratio and caspase-3 activity was lower in HCF-treated H1299 cells compared to the control cell. The fold change in VGEF and vimentin gene expression was higher in the HCF-treated H1299 cells than in the control cell. The scratch test results showed that H1299 cell mobility increased 24 and 48 hours after exposure to HCF. Our results suggest that the downregulation of miR-145 in HCF-treated H1299 cells may play a role as a possible oncogenic regulator of lung cancer growth. To confirm this assumption, further studies are required to evaluate the microRNA profile and effective oncogenes in vivo.
ABSTRACT
Echinococcosis, or hydatid disease, is a parasitic infection caused by a cestode from the Taeniidae family, mainly by Echinococcus multilocularis or granulosus. It is predominantly seen in the lungs or the liver. The hydatid disease rarely manifests as a palpable mass in the muscles. This study reports a case of a 70-year-old male who has presented with a swelling in the anterolateral aspect of his right upper thigh, which was progressive over the past two years. The swelling was initially painless and is now associated with pain. The clinical diagnosis of an abscess was suspected. The diagnosis of his swelling was later made as a hydatid cyst in a muscle of the thigh based on the imaging modalities, the ultrasound, and an MRI. The patient underwent surgical excision of the cyst, following which the diagnosis of a hydatid cyst was confirmed on the biopsy.
ABSTRACT
Hydatidosis is a zoonosis, caused by a cestode (Echinococcus). Management will depend on the organs affected by the infection and the response to medical treatment. Therapy may be clinical in early stages, but in case of poor response to drug therapy, surgery is the preferred choice. We present two cases in young females, the first case is with Hydatid cysts in both lungs and liver, she received initial medical treatment with lack of response, and surgery was indicated to resect the pulmonary and hepatic lesions. The second case is of a female with Hydatid cysts in the right lung. She was misdiagnosed at the beginning thinking of pneumonia and pulmonary abscess but after further investigation, hydatid cysts were the diagnosis, due to symptoms consistent with thoracic pain and persistent cough and the size of the cyst, surgery was indicated.
ABSTRACT
Hydatidosis, caused by the larval stage of Echinococcus granulosus, is a zoonotic disease typically affecting the liver and lungs. Cerebral localizations are rare, especially in the brainstem. We present a case of a 9-year-old boy with a brainstem hydatid cyst. The patient exhibited progressive walking difficulties and limb impairment. MRI revealed a brainstem mass consistent with a hydatid cyst. Due to the lesion's size and location, surgical intervention was necessary. The cyst was decompressed and removed without complications, followed by albendazole treatment. Postoperative recovery was uneventful, and the patient showed no signs of recurrence after 2 years. This case highlights the importance of early diagnosis, precise surgical techniques, and thorough postoperative care in managing rare cerebral hydatid cysts.
ABSTRACT
BACKGROUND: Echinococcosis is a parasitic disease caused by Echinocccus granulosus and Echinococcus multilocularis and declared a neglected tropical disease by the World Health Organization. The disease is a significant cause of morbidity and mortality, especially in India, Australia, China, Turkey, South America, the Middle East, and Eastern European countries. Bibliometric analysis is a popular research trend that gains the advantage of evaluating all the studies about one specific topic and emphasizing the importance and place of the subject in the literature. With this study, we aim to evaluate all the global published literature in the Web of Science core collection database about urinary tract echinococcosis between 1945 and 2024. METHODS: All documents indexed in the Web of Science core collection database between 1945 and 2024 were scanned on March 29, 2024. VOSviewer program 1.6.20 and MS Office Excel 2017 programs were used for forward analysis. RESULTS: 152 documents were obtained, 102 of which were indexed in SCI-Expanded journals. Turkey (21.71%) was the leading country in terms of the total number of documents, followed by India (21.05%), but citations of Indian publications were higher (21.77%). Spain was in the first rank in terms of average citations per document (19.33). Most of the documents were original articles (78.29%). Okan Akhan was the most prolific author, with three documents. The most-cited document was conducted in 1997 by Angulo et al. and received 74 citations. With seven publications, Urology Case Reports was the journal that published the most documents on urinary tract echinococcosis. CONCLUSIONS: Evaluating the studies on urinary system echinococcosis with bibliometric analysis, it is understood that although the number of studies has gradually increased over the years, they are still less than expected. We recommend that more studies be conducted to determine the true prevalence of echinococcosis and ensure more effective management of the disease, especially in countries where it is endemic.
ABSTRACT
BACKGROUND: Primary cardiac tumors are uncommon, with approximately 70-80% classified as benign. Myxomas constitute roughly half of all benign cardiac tumors, while cardiac hydatid cysts are exceptionally rare. Shortness of breath is a prominent symptom associated with these conditions. Echocardiography serves as the primary diagnostic tool, enabling early detection. The preferred course of action involves the surgical excision of the mass. CASE PRESENTATION: Our first case, a 51-year-old female presented to the cardiology outpatient clinic with complaints of shortness of breath and palpitations persisting for 3 months. Physical examination and tests were within normal limits. Echocardiography revealed a right atrial myxoma measuring 65 * 35 mm. Despite not affecting valve and ventricular functions, the mass was surgically resected. Our second case, a 55-year-old male admitted to the cardiology clinic with recurrent fever, shortness of breath, and chest pain. Physical examination and tests were normal. Echocardiography revealed an echogenic mass with a septate appearance adhering to the free wall of the right atrium. The patient, diagnosed with a hydatid cyst, underwent surgical resection. CONCLUSIONS: We came across two different cases of RA masses which happened to be myxoma and hydatid cysts, and we managed accordingly. The right atrial myxomas typically present with nonspecific shortness of breath unless they cause valve obstruction. In cases where clinical findings suggest infection in the right atrial masses, it is essential to consider hydatid cyst as a potential diagnosis alongside the initial consideration of vegetation.
ABSTRACT
There is a significant focus on the role of the host microbiome in different outcomes of human parasitic diseases, including cystic echinococcosis (CE). This study was conducted to identify the intestinal microbiome of patients with CE at different stages of hydatid cyst compared to healthy individuals. Stool samples from CE patients as well as healthy individuals were collected. The samples were divided into three groups representing various stages of hepatic hydatid cyst: active (CE1 and CE2), transitional (CE3), and inactive (CE4 and CE5). One family member from each group was selected to serve as a control. The gut microbiome of patients with different stages of hydatid cysts was investigated using metagenomic next-generation amplicon sequencing of the V3-V4 region of the 16S rRNA gene. In this study, we identified 4862 Operational Taxonomic Units from three stages of hydatid cysts in CE patients and healthy individuals with a combined frequency of 2,955,291. The most abundant genera observed in all the subjects were Blautia, Agathobacter, Faecalibacterium, Bacteroides, Bifidobacterium, and Prevotella. The highest microbial frequency was related to inactive forms of CE, and the lowest frequency was observed in the group with active forms. However, the lowest OTU diversity was found in patients with inactive cysts compared with those with active and transitional cyst stages. The genus Agatobacter had the highest OTU frequency. Pseudomonas, Gemella, and Ligilactobacillus showed significant differences among the patients with different stages of hydatid cysts. Additionally, Anaerostipes and Candidatus showed significantly different reads in CE patients compared to healthy individuals. Our findings indicate that several bacterial genera can play a role in the fate of hydatid cysts in patients at different stages of the disease.

Hydatid disease is a parasitic infection caused by a cestode from the Taeniidae family, by Echinococcus multilocularis or Echinococcus granulosus, predominantly occurring in the lungs and liver. Although the kidney can be involved in hydatid cysts, isolated kidney hydatidosis is very rare. Most cases present with non-specific complaints or remain asymptomatic for years. Hence, imaging is very useful in the diagnosis. Here, we report an isolated hydatid cyst involving the right kidney.
ABSTRACT
INTRODUCTION: "Hydatid cyst" or cystic Echinococcosis is a parasitic infection caused by the larval stage of Echinococcus granulosus. The liver and lungs are the most common sites to occur. Incidence in muscles is exceptionally rare. Surgery has been the traditional approach for treatment of cystic echinococcusis. PRESENTATION OF CASE: We report a rare case of 44 years old man with multiple hydatid cysts; liver, lungs, paraspinal muscles. The muscular cyst had manifested as a swelling in his back and was the principal clinical presentation as it caused pain and discomfort. He was treated with Albendazole, and a thoracic surgery for the management of the lung cysts had been performed. On admission and after his surgery, lymphadenopathy had manifested and following adequate diagnostic modalities he was diagnosed with Non-Hodgkin lymphoma. Then, after three months, physical examination revealed significant reduction in the size of his back cyst that was no longer visible. DISCUSSION: Here we present a successful treatment for muscular hydatid cysts. While prior reports have managed it surgically; albendazole has played a significant role in our case, in addition to the diagnosis of the NHL in the course of managing multiple hydatid cysts. CONCLUSION: The presence of non-Hodgkin lymphoma alongside hepatic cystic disease is rare, and the coexistence of NHL and muscular hydatidosis is unprecedented in medical literature.
ABSTRACT
Echinococcus ortleppi is the genotype G5 of Echinococcus granulosus sensu lato and is a zoonotic canine tapeworm of which larvae causes cystic diseases in domestic animals and also humans. While this species is highly endemic and widely spread in domestic animals, human infection is extremely rare and only sporadic, and thus, entire picture of human cystic echinococcosis due to infection with E. ortleppi is unclear. We have made an extensive literature review on the cases of E. ortleppi infection in humans and found a total of 19 cases from various places in the world with recent emergence in Asian countries.
ABSTRACT
Eosinophilic gastritis, a rare variant of gastritis, presents with inflammation of the stomach lining due to eosinophil infiltration. This case report describes a complex presentation of eosinophilic gastritis in a 12-year-old boy, highlighting the challenges encountered in management. A 12-year-old male presented with symptoms consistent with gastritis, including abdominal pain, nausea, and vomiting. Despite extensive medical workup to identify potential etiologies (parasitic infections, autoimmune conditions), the diagnosis of eosinophilic gastritis was established. Unfortunately, the patient exhibited persistent symptoms despite aggressive medical management. The case was further complicated by pyloric stenosis, a narrowing of the stomach outlet. Laparoscopic intervention, a minimally invasive surgical approach, was initially attempted but deemed challenging due to the patient's specific condition. The presence of metabolic abnormalities added further complexity. Alternative approaches, such as endoscopic dilatation, were considered but ultimately deemed unsuitable due to the severity of the stenosis and the desire for a minimally invasive solution compared to laparotomy. This case exemplifies the challenges associated with managing rare gastrointestinal conditions like eosinophilic gastritis, particularly in pediatric patients. The report emphasizes the importance of a multidisciplinary approach, involving collaboration between gastroenterologists, surgeons, and potentially other specialists depending on the specific complications, to achieve optimal outcomes. This case highlights the complexities in managing this patient, especially when accompanied by complications like pyloric stenosis. It underscores the crucial role of a multidisciplinary team in navigating challenging presentations and exploring minimally invasive surgical options when feasible.
ABSTRACT
Hydatidosis is a parasitic disease caused by the tapeworm Echinococcus. Echinococcus Granulosus is the most common cause of hydatid disease in humans. Bone involvement is rare, accounting for only 0.9% to 2.5% of all cases. We report the case of an 8-year-old child admitted with right arm pain, revealing a hydatid cyst on the humerus. Lesion assessment revealed a hydatid cyst of the humerus with extension to the adjacent soft tissues. The surgical procedure involved the excision of the cyst along with drainage. In this case report, we review the epidemiological, clinical, and paraclinical aspects of the disease, as well as the treatment modalities. Bone hydatid disease is infiltrative, diffuse, slow, and progressive, making diagnosis late, and compromising the quality of treatment.
ABSTRACT
Hydatid disease, caused primarily by Echinococcus granulosus, is prevalent in regions where livestock farming is common. Although typically considered benign, ruptured hydatid cysts into the abdominal cavity present a rare but severe complication requiring urgent surgical intervention. We hydatid liver cyst, emphasizing the unprecedented nature of this occurrence, as it has never been reported in the literature before. The case underscores the role of computed tomography (CT) imaging in diagnosis and multidisciplinary management involving emergency physicians, radiologists, anesthetists, and surgeons. Key points highlighted include the rarity of postpartum hydatid cyst rupture, the diagnostic utility of CT scans, and the necessity of immediate surgical intervention. Surgical strategies include conservative techniques and intraoperative lavage with hypertonic saline solution to prevent recurrence. Postoperative albendazole therapy and regular follow-up aid in preventing recurrence and early detection of complications. This case underscores the importance of suspecting ruptured hydatid cysts in postpartum women with underlying hepatic hydatid cyst and features of peritonitis, necessitating prompt recognition and management of complications in hydatid disease.
ABSTRACT
The term "hydatid disease" refers to echinococcosis. Echinococcosis is a zoonotic disease caused by the larval stage of the Echinococcus parasite. The disease is widespread in regions where the parasite is endemic, particularly in developing nations like India. However, there are only a couple of documented case studies of echinococcosis associated with hematological malignancy in the literature. We present an extremely uncommon case of a 36-year-old male who had liver hydatidosis and was diagnosed with acute myeloid leukemia (AML)-M1. The patient received treatment for acute myeloid leukemia (daunomycin, cytarabine, and 5-azacytidine), followed by management of hydatid disease after complete remission of acute leukemia. The patient underwent periodic evaluations for one year and exhibited satisfactory improvement.
ABSTRACT
Introduction: Hydatid disease of the male breast has not been documented in literature to date. Case report: We present a case of a 46-year old male patient who presented with a painful breast lump for 1 year. On imaging, it was suspicious for hydatid disease of the breast and was successfully diagnosed preoperatively on fine-needle aspiration cytology and histopathology as hydatid disease of the breast. Discussion: Incidence of hydatid disease of the breast contributes to a minute number of total cases of hydatid disease. Male breast hydatid disease was unknown prior to this report. We did find similarities in the imaging features of our case and the ones described for female breasts. On ultrasonography, we found it analogous to the 'water-lily' sign which has been described in hepatic hydatic cysts. Conclusion: Keeping hydatid disease as a differential in the setting of a suspicious breast mass even in a male patient proved to be rewarding as it negated the need for further cross-sectional imaging and a definitive diagnosis could be sought based on the fine-needle aspiration cytology and histopathological findings.
