Abstract
BACKGROUND Sparganosis is a rare zoonotic disease caused by plerocercoid larvae of the genera Spirometra or Sparganum (Cestoda: Diphyllobothriidae). The larvae of Spirometra generally do not undergo asexual reproduction, whereas those of Sparganum can induce proliferative lesions in infected tissues. This paper presents an unusual case of proliferative sparganosis due to infection with Spirometra mansoni in a cat, normally considered a definitive host of the species. CASE PRESENTATION A 9-year-old male domestic cat was presented with a mass on the right side of the face that underwent progressive enlargement for 1 month. The morphological and histopathological examinations revealed multiple asexual proliferative cestode larvae in the lesions, suggestive of proliferative sparganosis. Next-generation sequencing analysis of formalin-fixed and paraffin-embedded specimens of surgically excised tissue indicated that the worm was Spirometra mansoni. CONCLUSION Although S. mansoni a common tapeworm species found in the small intestine of domestic cats and dogs in Japan, proliferative sparganosis is extremely rare. This is the first confirmed case of proliferative sparganosis due to infection with S. mansoni in cat.

Abstract
Cats normally play a role of the definitive host in which the plerocercoid (sparganum), the second larval form of Spirometra spp., develops into an adult in the intestines. However, some cases of cats with visceral or subcutaneous sparganosis were sporadically reported worldwide. We herein documented the discovery of a sparganum in abdominal cavity of a domestic cat during a surgery of dystocia. The larva was molecularly identified as Spirometra mansoni, belonging to Type I, that was recently misidentified to be S. erinaceieuropaei in several Asian countries. This is the first report for sparganum of S. mansoni in the cat. The future study is necessary to provide further insights into the species of Spirometra causing sparganosis and spirometrosis in humans and other animals.

Abstract
IntroductionCerebral sparganosis is a rare parasitic infection of the brain tissue. The remission of MRI change and clinical symptom has been used to evaluate the therapeutic effect. However, there is no study to correlate the serum IgG antibody level of sparganum to the prognosis of disease after treatment. Methods87 patients with cerebral sparganosis were collected from three medical centers. Clinical symptoms and MRI changes were evaluated at 12 months after initial treatment, and serum IgG antibody level of sparganum was evaluated at 2, 6, and 12 months after treatment. The positive cut-off value was based on 2.1 times the optical density (OD) of negative control. The index value was defined as the sample OD divided by the cut-off value.ResultsAmong the 87 patients after treatment, 71 patients had good clinical outcomes, and 16 had poor clinical outcomes. The area under the curve (AUC) showed that the index value measured at 12 months after treatment had the best prediction effect, with a value of 2.014. In the good-outcome group, the index values were less than 2.014 in all 71 patients, and only 8 patients had mildly enhanced residual lesions on MRI. In the poor-outcome group, the index values were more than 2.014 in all 16 patients, and all patients still showed significantly enhanced lesions on MRI. Compared with poor-outcome patients, only 2 patients with good outcomes had disease recurrence after treatment.DiscussionThis study provided evidence that the serum IgG antibody level of sparganum was a promising biomarker to evaluate the prognosis of patients with cerebral sparganosis after treatment.

Abstract
The patient was found to develop a migrating mass in the lower abdomen without any known cause in 2000, and the cause had not been identified following multiple diagnoses since then. The mass was found to migrate to the left anterior axillary regions on August 11, 2020. Then, three segments of incomplete white worms were resected through minimally invasive surgery, and metagenomic sequencing revealed sparganosis mansoni. After surgical resection of complete worms was performed on October 21, 2021, the case was cured and discharged from the hospital. Follow-up revealed satisfactory outcomes and no new mass was found throughout the body.

Abstract
Human sparganosis is a food-borne parasitic disease caused by the plerocercoids of Spirometra species. Clinical diagnosis of sparganosis is crucial for effective treatment, thus it is important to identify sensitive and specific antigens of plerocercoids. The aim of the current study was to identify and characterize the immunogenic proteins of Spirometra erinaceieuropaei plerocercoids that were recognized by patient sera. Crude soluble extract of the plerocercoids were separated using 2-dimensional gel electrophoresis coupled with immunoblot and mass spectrometry analysis. Based on immunoblotting patterns and mass spectrometry results, 8 antigenic proteins were identified from the plerocercoid. Among the proteins, cysteine protease protein might be developed as an antigen for diagnosis of sparganosis.

Abstract
OBJECTIVE To investigate the prevalence of Spirometra mansoni infections in hosts in Jiangsu Province, so as to provide the scientific basis for the management of sparganosis mansoni. METHODS From 2018 to 2019, nine counties (cities, districts) were randomly selected from Jiangsu Province as the survey sites, and 100 healthy individuals were randomly selected to perform the serological test of S. mansoni infections and the detection of S. mansoni eggs. The procercoids were detected in the intermediate host Cyclops, and the S. mansoni eggs were identified in the stool samples of the definitive hosts cats and dogs. RESULTS The prevalence of S. mansoni human infections was 0 (0/900) in the 9 survey sites of Jiangsu Province, and the sero-prevalence of the specific IgG antibody against S. mansoni was 1.22% (11/900). The positive rate of procercoids was 0.33% (3/900) in Cyclops. In addition, the S. mansoni egg-positive rate was 1.48% (2/135) in cats and dogs. CONCLUSIONS Sparganosis mansoni is prevalent in Jiangsu Province. Health education pertaining to the damages of sparganosis mansoni and the route of S. mansoni infections should be improved.

Abstract
RATIONALE Sparganosis is an infectious disease caused by a larval tapeworm of the genus Spirometra, which commonly invades subcutaneous tissues. Pulmonary and pleural involvement due to sparganum has been rarely reported previously. PATIENT CONCERNS We herein described a case of recurrent eosinophilic pleuritis in a 24-year-old woman. She was admitted with persistent cough and shortness of breath for more than 1 month. Initial chest computed tomography scan suggested right pleural effusion and diffuse pleural thickening. Slightly elevated eosinophil counts were found in both the peripheral blood and pleural fluid. She underwent right pleurectomy but histological examination failed to obtain an etiological diagnosis. Moreover, eosinophilic pleural effusion re-appeared in the contralateral thoracic cavity one month later. After re-admission, we reviewed her medical history meticulously and found she had a history of ingesting raw snake gallbladders before hospitalization. The final diagnosis was confirmed by the markedly positive reaction against sparganum antigen in both serum and pleural fluid sample. DIAGNOSIS Eosinophilic pleuritis caused by sparganum infection. INTERVENTIONS After the diagnosis, the patient was treated with praziquantel at 75 mg/kg/d for 3 days. OUTCOMES Pleural effusion absorbed completely and eosinophil count in peripheral blood returned to normal range. No evidence of recurrent pleural effusion had been observed in over one year of follow-up. LESSONS Clinicians need to be aware the possibility of sparganum infection in cases of eosinophilic pleuritis. The specific enzyme-linked immunosorbent assay remains a useful method in acquiring a rapid diagnosis, especially when histological examination is unable to detect the larvae in the thoracic cavity.

Abstract
Sparganosis is a parasitic infestation caused by sparganum, a plerocercoid tapeworm larva of the genus Spirometra. Since the first case of human sparganosis reported in 1908, sparganosis has been a global disease, and is common in China, Japan, and Southeast Asian countries. Consumption of raw snakes, frogs, fish, or drinking contaminated beverages are sources of human infections. Human sparganosis usually manifests in subcutaneous fat in areas such as the abdomen, genitourinary tract, and limbs. Breast sparganosis cases are rare, representing less than 2% of total cases of human infections. Complete surgical extraction of the sparganum is the treatment of choice. Because of the rarity of the disease, clinical suspicion is vital to reach the diagnosis of breast sparganosis. Here we report 2 rare cases of breast sparganosis presenting with a painless breast lump, both treated with surgical excision and sparganum extraction.

Abstract
BACKGROUND Sparganosis is a larval cestodiasis caused by the plerocercoid of Spirometra spp. Since the first description of human sparganosis in 1924, several hundred cases have been reported in Korea. However, systematic approaches for literature surveys of Korean sparganosis have seldom appeared. METHODS We searched publicly available databases such as PubMed, Research Information Sharing Service, and Korea Medical Citation Index with relevant Medical Subject Headings. RESULTS At least 438 Korean sparganosis cases have been described from 1924 to 2015. Preoperative diagnosis has been significantly increased since the 1980s due to popularization of serological and imaging diagnostics. Cases were largely detected from fifth decades in general, but cerebral sparganosis was detected in relatively young age groups (third and fourth decades). Sparganosis was prevalent in men (75.9%). Consumption of frog/snake and drinking unfiltered water were found in 63.4% and 16.9% of patients, respectively. Most frequently affected sites were subcutaneous tissues (49.9%), followed by the central nervous system (36.2%). Involvements of visceral organs (7.6%), ocular regions (3.6%), and muscles (2.7%) were noticed. In women, breast sparganosis constituted a large proportion (34.2%). Sparganosis associated with immunocompromised patients has recently been reported. CONCLUSION Sparganosis has been continuously reported in Korea during the past 90 years, although its incidence has decreased during the last 20 years. The disease is mostly characterized by subcutaneous nodule, but infection of the worm in vital organs often results in serious illness. Continuous awareness is warranted to monitor sparganosis occurrence and associated clinical consequences.

Abstract
Some fish parasites constitute severe management problems as they may cause mortality of their fish host or are important zoonoses of humans. Parasite assessments are therefore critical to keep track of infections. If conventional sampling techniques can be simplified, parasite assessments might be easier to obtain, less time-consuming and more extensive. In this study, we compare the assessed number of Diphyllobothrium spp. cysts (CYST) with the counted number of Diphyllobothrium spp. plerocercoid larvae recovered using a conventional digestive technique (LARV). The aim was to determine the potential of using CYST as a simplified methodology for assessing Diphyllobothrium spp. infection in salmonids. In total, 365 brown trout and 424 Arctic charr were sampled from nine lakes in subarctic Norway. Strong correlation, significant linear relationship and large amount of explained variation were found between log10 CYST and log10 LARV in both fish species. The method had a slight, but not significant tendency to work better in charr compared to trout. In addition, absolute difference between CYST and LARV increased at parasite intensities >100 indicating that the method has reduced functionality when estimating parasite intensity in heavily infected salmonid populations. However, overall, using this simplified and less time-consuming methodology, a good indication of Diphyllobothrium spp. intensity, abundance and prevalence was obtained. We suggest that this method provides a sound proxy of the Diphyllobothrium spp. burden and have the potential to be used in parasite assessment during fish monitoring and fisheries management surveys, particularly if the time and resources for detailed parasite studies are not available.

Abstract
It is clinically important to differentiate tissue-invading helminthiasis. The purpose of this study was to assess the specific immunoglobulin G (IgG) antibody positive rates for clonorchiasis, paragonimiasis, cysticercosis, and sparganosis 4 helminthiases from 1996 to 2006 using multi-antigen enzyme-linked immunosorbent assay (ELISA) in Korea. Results of 6,017 samples, which were referred to our institute for serodiagnosis, were analyzed. The subjects with positive serum IgG antibodies were 1,502 (25.0%) for any of the 4 helminthiases. The overall positive numbers for clonorchiasis, paragonimiasis, cysticercosis, and sparganosis were 728 (12.1%), 166 (2.8%), 729 (12.1%), and 263 (4.4%), respectively. The positive serologic reaction to multi-antigens was determined in 309 (20.6%) of the 1,502 total seropositive subjects. Those with multi-antigen positivity were regarded as positive for the antigen of strongest reaction but cross-reaction to others with weak positive reaction. Annual seropositive rates for those 4 tissue helminthiases ranged from 12.1% to 35.7%. The highest rate was observed in age from 60 to 69 years old and prevalence of men (27.4%; 1,030/3,763) was significantly higher than of women (19.1%; 332/1,741). Hospital records of 165 ELISA positive patients were reviewed to confirm correlation with their clinical diagnosis. Paragonimiasis was highly correlated as 81.8% (9/11), cysticercosis 29.9% (20/67), clonorchiasis 29.0% (20/69), and sparganosis 11.1% (2/18). In conclusion, the multi-antigen ELISA using 4 helminth antigens is useful to differentiate suspected tissue-invading helminthiases, especially ELISA diagnosis of paragonimiasis is reliable. The seropositivity is still high among suspected patients in Korea.

Abstract
Human sparganosis is a rare parasitic disease caused by infection with the tapeworm Sparganum, the migrating plerocercoid (second stage) larva of Spirometra species. Sparganosis usually involves subcutaneous tissues and/or muscles of various parts of the body, but involvement of other sites such as the brain, eye, peritoneopleural cavity, urinary track, scrotum, and abdominal viscera has also been documented. Infections caused by sparganum have a worldwide distribution but are most common in Southeast Asia such as China, Japan, and South Korea. Rectal sparganosis is an uncommon disease but should be considered in the differential diagnosis of unusual and suspicious rectal submucosal tumors. We report a case of rectal sparganosis presenting as rectal submucosal tumor. We performed endoscopic submucosal dissection of the rectal submucosal tumor. The sparganosis was confirmed based on the presence of calcospherules in the submucosal layer on histological examination. Moreover, the result of the immunoglobulin G antibody test for sparganosis was positive but became negative after endoscopic submucosal dissection. Though rare, rectal sparganosis should be considered in the differential diagnosis of rectal submucosal tumor-like lesions. This case suggests that physicians should make effort to exclude sparganosis through careful diagnostic approaches, including detailed history taking and serological tests for parasites. In this report, we aimed to highlight the clinical presentation of Sparganum infection as a rectal submucosal tumor.

Abstract
Brain sparganosis is a non-common parasite infection by Diphyllobothrium or Spirometra mansonoides larvae. This last one is responsible for most of the infestations in humans. We report a 19 years male patient bearer of a brain sparganosis. The patient presented with headache and left hemiparesis. CT diagnosis of right thalamic lesions was made and aspiration biopsy was performed using stereotactic system, obtaining a whole and death larvae. Histopathology confirms a CNS parasitism and it was treated initially with albendazol. ELISA test confirmed Spirometra spp. infestation. The patient developed asymptomatic with total remission of the lesions. It constitutes the second report in Cuba of brain sparganosis.

Abstract
Human sparganosis is a food borne zoonosis caused by the plerocercoid larvae (spargana) of various diphyllobothroid tapeworms of the genus Spirometra. Human infections are acquired by ingesting the raw or undercooked meat of snakes or frogs, drinking untreated water, or using raw flesh in traditional poultices. More than 1600 cases of sparganosis have been documented worldwide, mostly in east and southeast Asia. Sporadic cases have been reported in South America, Europe, and Africa, and several cases have been described in travellers returning from endemic regions. Epidemiological data suggest that the increased effect of sparganosis on human health is because of greater consumption of raw meat of freshwater frogs and snakes. This Review provides information about the Spirometra parasites and their lifecycles, summarises clinical features, diagnosis, and treatment of human sparganosis, and describes geographical distribution and infection characteristics of Spirometra parasites in host animals.

Abstract
Thirty-seven unusual specimens, three from Ethiopia and 34 from South Sudan, were submitted since 2012 for further identification by the Ethiopian Dracunculiasis Eradication Program (EDEP) and the South Sudan Guinea Worm Eradication Program (SSGWEP), respectively. Although the majority of specimens emerged from sores or breaks in the skin, there was concern that they did not represent bona fide cases of Dracunculus medinensis and that they needed detailed examination and identification as provided by the World Health Organization Collaborating Center (WHO CC) at Centers for Disease Control and Prevention (CDC). All 37 specimens were identified on microscopic study as larval tapeworms of the spargana type, and DNA sequence analysis of seven confirmed the identification of Spirometra sp. Age of cases ranged between 7 and 70 years (mean 25 years); 21 (57%) patients were male and 16 were female. The presence of spargana in open skin lesions is somewhat atypical, but does confirm the fact that populations living in these remote areas are either ingesting infected copepods in unsafe drinking water or, more likely, eating poorly cooked paratenic hosts harboring the parasite.

Abstract
Background Sparganosis is a neglected but important food-borne parasitic zoonosis. Clinical diagnosis of sparganosis is difficult because there are no specific manifestations. ELISA using plerocercoid crude or excretory–secretory (ES) antigens has high sensitivity but has cross-reactions with other helminthiases. The aim of this study was to characterize Spirometra erinaceieuropaei cysteine protease (SeCP) and to evaluate its potential application for serodiagnosis of sparganosis. Methodology/Principal Findings The full length SeCP gene was cloned, and recombinant SeCP (rSeCP) was expressed and purified. Western blotting showed that rSeCP was recognized by the serum of sparganum-infected mice, and anti-rSeCP serum recognized the native SeCP protein of plerocercoid crude or ES antigens. Expression of SeCP was observed at plerocercoid stages but not at the adult and egg stages. Immunolocalization identified SeCP in plerocercoid tegument and parenchymal tissue. The rSeCP had CP activity, and the optimum pH and temperature were 5.5 and 37°C, respectively. Enzymatic activity was significantly inhibited by E-64. rSeCP functions to degrade different proteins and the function was inhibited by anti-rSeCP serum and E-64. Immunization of mice with rSeCP induced Th2-predominant immune responses and anti-rSeCP antibodies had the potential capabilities to kill plerocercoids in an ADCC assay. The sensitivity of rSeCP-ELISA and ES antigen ELISA was 100% when performed on sera of patients with sparganosis. The specificity of rSeCP-ELISA and ES antigen ELISA was 98.22% (166/169) and 87.57% (148/169), respectively (P<0.05). Conclusions The rSeCP had the CP enzymatic activity and SeCP seems to be important for the survival of plerocercoids in host. The rSeCP is a potential diagnostic antigen for sparganosis. Sparganosis is a neglected tropical disease; its diagnosis is difficult and it is often misdiagnosed. ELISA using the crude or ES antigens of plerocercoids cross reacts with other helminthiases. Cysteine protease is a type of hydrolase and plays important roles in the development and survival of parasites; it has been used for diagnostic markers and vaccine targets for some parasitic diseases. In this study, a 36 kDa Spirometra erinaceieuropaei cysteine protease (SeCP) was expressed and purified. The results showed that SeCP was a plerocercoid stage-specific protein located in the teguments and parenchymal tissue. The rSeCP had cysteine protease activity and functioned to degrade host proteins. Vaccination of mice with rSeCP induced high levels of IgG1 and anti-rSeCP antibodies with the ability to kill plerocercoids in an ADCC assay. The rSeCP had a high sensitivity and specificity for detecting anti-plerocercoid antibodies, and could be used as a potential antigen for serodiagnosis of sparganosis.

Abstract
We herein report a rare form of sparganosis in a 29-year-old man presenting with pericardial effusion and lung lesions. The diagnosis was confirmed by the patient's history of eating inadequately cooked snake, significant elevated eosinophils in the peripheral blood and pericardial effusion, and marked positive reactions against Sparganum mansoni antigen in the serum. After two consecutive doses of praziquantel treatment, the patient's symptoms and laboratory and imaging findings were improved. Both specific antibody detection and follow-up of the patient's eosinophils, serum antibody, and imaging changes are important for sparganosis diagnosis, particularly in cases without a subcutaneous lump or mass.

Abstract
OBJECTIVE To improve the understanding of pleural sparganosis by analyzing a clinical case and literature review. METHODS The clinical data of a patient with pleural sparganosis diagnosed by immunoserology and pathology was analyzed. The data of 6 cases from literature reports regarding pleural sparganosis were reviewed through database including PubMed, VIP, Wanfang and China Knowledge Resource Integrated Database. The clinical characteristics, diagnosis and treatment of the 7 cases were summarized and analyzed. RESULTS A 38-year-old man was admitted to our hospital with right pleural effusion, and received the final diagnosis of pleural sparganosis according to increase of eosinophils in blood and plural effusion, positive sparganum-mansoni antibody in serum, and parasite bodies in pleural tissues biopsied with medical thoracoscopy. The patient was treated successfully with consecutive three-day doses of praziquantel (75 mg × kg⁻¹ × d⁻¹). The documents reported 6 cases of pleural sparganosis on the database of PubMed, Wafang,VIP and China Knowledge Resource Integrated Database. Pleural effusion was found in 5 cases by chest radiograph or CT.Serum sparganum-mansoni antibody assays were strongly positive in 5 cases, and sparganosis bodies were confirmed by pleural histological findings in 3 cases. Two patients received video-assisted thoracic surgery examinations. Six patients recovered with the treatment of praziquantel. CONCLUSIONS Pleural sparganosis is a rare disease. Patients with increase of eosinophils in blood and pleural effusion should receive serum sparganum-mansoni antibody test to avoid misdiagnosis of pleural sparganosis. Medical thoracoscopy plays an important role in the diagnosis of pleural sparganosis.

Abstract
Sparganosis is a parasitic infestation of human by plerocercoid larvae. Sparganum is usually reported to be found in the subcutaneous tissues as well as other organs, including scrotum. However, testicular sparganosis is extremely rare, because of strong capsule of tunica albuginea. An urban-living 54-yr-old Korean man presented with left scrotal pain for 6 yr. Both testes look normal physically. Ultrasonography revealed poorly defined, heterogeneous mass with increased echogenicity in the left testis. This case was misdiagnosed as testicular tumor and underwent orchiectomy, but was diagnosed as testicular sparganosis by histopathology. Sparganosis should be included for differential diagnosis of testis tumor in countries where sparganosis is prevalent.

Abstract
In order to identify early specific diagnostic antigens of Spirometra erinaceieuropaei (syn. S. erinacei or S. mansoni) sparganum, soluble proteins were analyzed by two-dimensional electrophoresis (2-DE) and western blotting probed with immune sera from infected mice at 14 days post-infection. From a total of approximately 462 proteins spots mainly distributed in pI range of 5-6.6 and with molecular mass of 25-48 kDa, 6 immuno-reactive protein spots with molecular mass of 31.8-38.3 kDa were characterized by MALDI-TOF/TOF-MS. Three proteins were identified as S. erinaceieuropaei cysteine protease, Toxoplasma gondii hypothetical protein and Pecten spp actin, while the remaining were unidentified. The cysteine protease from S. erinaceieuropaei soluble proteins recognized by early infection sera might be developed as diagnostic reagent for early detection of sparganosis.

Abstract
Sparganosis is an infection by the parasitic tapeworm larvae of Spirometra species. Ocular sparganosis is a rare disease that is easily misdiagnosed. We reported a rare case of ocular sparganosis mimicking orbital idiopathic inflammatory syndrome at initial presentation. A 34-year-old female presented with rapid progressive swelling of her left eyelid and mild proptosis for the duration of one month. The other ocular examinations were normal and the thyroid function was normal. Magnetic resonance imaging revealed a fusiform enlargement and mild heterogenous enhancement of the superior oblique muscle of the left orbit. First she received prednisolone therapy and the proptosis partially improved. Six months later, a white, flat and wrinkled string like worm wriggled out from the caruncular conjunctiva of the left eye. The pathology results confirmed that the worm was a Spirometra species larva. After removal of the larva and treatment with praziquantel, the proptosis was resolved without recurrence. Ocular sparganosis is a rare disease and only a few case reports have been reported. The drug therapy has not been effective and the surgical removal is the principal therapy. Despite its rarity, ocular sparganosis should be considered as a possible cause of orbital inflammation in patients.

Abstract
OBJECTIVE To analyse the clinical features of sparganosis patients and improve cognition in the disease. METHODS The epidemic data, clinical manifestations, auxiliary examinations, diagnosis and treatments of 25 sparganosis patients in the hospital were retrospectively analyzed. RESULTS Among the 23 patients with definite epidemiological data , 22 cases were food-borne, one case of contact infection. According to the clinical manifestation, there were 14 cases of central nervous system (CNS) sparganosis, 7 cases of cutaneous sparganosis, 3 cases of visceral sparganosis and 1 case of ocular sparganosis. Eosinophilia in peripheral blood was found in 4 cases including the 3 cases of visceral sparganosis. 22 patients were diagnosed by serologic IgG antibody test. MRI showed positive finding in all CNS sparganosis patients. 11 cases received surgical excision or biopsy, worms were found in 8 cases. 80% of the cases were once misdiagnosed by other disorders. 18 patients were cured and 7 alleviated after treatment. CONCLUSION Sparganosis is mostly a food-borne infection, more involving central nervous system. Serologic test is important for diagnosis, and eosinophilia is uncommon.

Abstract
The diagnosis and treatment of one case of cerebral sparganosis suggests that stereotactic positioning operation is an effective treatment, and understanding of the spectrum of parasitic diseases is helpful for the diagnosis and differential diagnosis. However, in non-epidemic area of sparganosis, the classical epidemiological route of transmission is difficult to satisfy the explanation of the current status of the disease.

Abstract
OBJECTIVE To diagnose 10 cases of clinically suspected cases of sparganosis mansoni by pathogen identification. METHODS In the period from August 2009 to August 2011, 10 biopsy specimens were obtained from 10 patients of four hospitals to identify the pathogen. Among the 10 cases, 4 cases showed abdominal subcutaneous mass, 3 showed eyelid swelling, 1 displayed brain lesions, 1 showed pulmonary mass, and 1 showed pleural effusion. There was one parasite each from three patients with eyelid swelling, and one patient with abdominal subcutaneous mass, which were observed by naked eye and microscope morphologically and histologically. Specimens from other six cases were examined by microscope after paraffin embedding, sectioning, and HE staining. For further identification, the parasite biopsy tissue specimens were detected by immunohistochemistry with Sparganum mansoni-immunized rabbit serum as the primary antibody. RESULTS Three intact worms, from three patients with eyelid swelling, showed typical S. mansoni morphological characteristics. One residue parasite from the abdominal subcutaneous mass showed network structures and full of calcareous corpuscles in the body under microscope same as that of S. mansoni. The histological structure in three of the six sections showed typically the body wall with folds, which was dense, thick and deeply eosine stained, part of the tegument outside was covered by micro-hairs. In the worm body there was net-like loose structure and calcareous corpuscles without cavity. The structure of the other three worm sections was atypical. The six worm sections were positive by immunohistochemical detection. CONCLUSION The 10 clinically suspected cases are diagnosed as sparganosis mansoni.

Abstract
Pulmonary sparganosis mansoni is uncommon in general clinical practice, but prevalent in endemic foci. Pulmonary sparganosis mansoni shares some clinical and radiologic similarities that mimic other common pulmonary pathogens. Delayed diagnosis of pulmonary sparganosis mansoni can pose a significant hazard to the patient. Indeed, a history of ingesting uncooked stone cracks in endemic areas is strongly suggestive of the possibility of pulmonary sparganosis mansoni. We report a case of a 43-year-old male peasant infested with pulmonary sparganosis mansoni who had been misdiagnosed with pulmonary tuberculosis.

Abstract
Seroprevalence of the IgG antibodies for Clonorchis sinensis, Paragonimus westermani, Taenia solium metacestode (cysticercus), and Spirometra erinacei plerocercoid (sparganum) was measured using enzyme-linked immunosorbent assay (ELISA) in sera of patients in Korea from 1993 to 2006. A total of 74,448 specimens referred nationwide from 121 hospitals revealed an IgG positive rate of 7.6% for the 4 parasites. The IgG positive rate (18.7%) for the 4 parasites in 1993 decreased gradually to 6.6% in 2006. Individual positive rate decreased from 5.2% (1993) to 1.6% (2006) for C. sinensis, from 2.8% (1993) to 1.1% (2006) for P. westermani, from 8.3% (1993) to 2.2% (2006) for cysticercus, and from 2.6% (1993) to 1.6% (2006) for sparganum. The positive rate was highest (21.2%) in the group of patients who ranged in age from 50-59 yr old, and in the group that was referred from the Seoul area (55.9%). In conclusion, our results suggest that tissue invading parasitic infections should always be included in differential diagnosis for patients with eosinophilia associated lesions of the central nervous system, liver, and lungs in Korea.

Abstract
Sparganosis is a rare parasitic infection in humans caused by a larval cestode of the genus Spirometra. Spargana invade muscle, subcutaneous tissue, the eye, urogenital, and abdominal viscera, but the central nervous system (CNS) is not a frequent site of invasion. Here, we describe an 18-year-old patient with cerebral sparganosis and review data from other cases reported in the medical literature.

Abstract
OBJECTIVE To study the value of MRI in the diagnosis of cerebral sparganosis in children. METHODS The MRI appearances of 17 children with cerebral sparganosis proven by pathology or serological test were retrospectively studied. The diagnostic accuracy rate of cerebral sparganosis was compared before and after knowing the imaging features of this disease. RESULTS Enhanced MRI was performed in 12 cases, and all of them demonstrated abnormal enhancement. Peripheral ring-type, tortuous beaded shape or serpiginous tubular shape enhancement were found in 8 cases. After analysis of follow-up MRI for 7 cases, a change in location and shape of lesions was found in 2 cases. Typical MRI patterns of cerebral sparganosis included abnormal enhancement such as peripheral ring-type, tortuous beaded shape or serpiginous tubular shape enhancement, and changes in location and shape of lesions in the follow-up MRI. The diagnostic accuracy rate for the 17 cases of cerebral sparganosis at the first visit, after first imaging examination and after several follow-up MR examinations were 0%, 11.8% and 28.6%, respectively. The diagnostic accuracy rate of this disease increased to 64.7%, 70.6% and 85.7% respectively after the radiologists were trained in the imaging characteristics of the disease. CONCLUSIONS MR findings in children with cerebral sparganosis are specific. Mastering correctly the typical imaging features of the disease can be very helpful in reducing the rate of clinical misdiagnosis.

Abstract
Herein, we report a rare case of subcutaneous sparganosis in a 60-year-old Japanese woman. She had a 2 cm x 2 cm elastic-hard, subcutaneous nodule, which was the larva of a tapeworm, and a surrounding granuloma in her internal thigh. It was thought that she became infected by drinking water contaminated with the worm. She was definitively diagnosed by enzyme-linked immunosorbent assay (ELISA). After excision of the lesion, the titer of ELISA showed clear decline; therefore, we could conclude that she had been completely freed from sparganosis. The magnetic resonance imaging (MRI) and ultrasound sonography of her subcutaneous nodule demonstrated the characteristic signs: a band-like structure in the MRI and a coiled linear hypoechoic body in a clear, oval mass in the ultrasound sonography.

Abstract
BACKGROUND Sparganosis is the infection of a paratenic host with the plerocercoid metacestode of Spirometra spp. A 12-year-old captive, pregnant, wild-caught baboon from Tanzania had multiple subcutaneous nodules. METHODS Examination of the biopsied nodules revealed the presence of viable metacestodes. The histological morphology of the metacestodes was consistent with the genus Spirometra and other pseudophyllidean cestodes. Since species of Spirometra produce growth hormones that are active in mammals, we measured fetal and placental growth and hormone levels. Blood samples were taken from the mother and the cesarean-derived fetus for hematological, biochemical, and hormonal analyses and to test for the presence of antispargana antibodies. RESULTS Baboon placental weight and fetal hematological, biochemical, and morphometric parameters were within normal ranges. Antibody titers to spargana did not differ significantly between mother (1.08 OD(405)) and fetus (0.91 OD(405)). Baboon maternal insulin-like growth factor and growth hormone values were also within the normal range. Estradiol and progesterone analysis in four of these animals (antibody titers ranged from 0.71 to 1.7 OD(405)) showed no statistically significant difference with age- or phase-matched cycle parameters compared with antibody-negative females. CONCLUSIONS Based on the results that have been obtained, sparganosis did not appear to affect the endocrinological profile of pregnant and cycling female baboons.

Abstract
The authors report a case of 14-year-old boy presented to the Ophthalmologic Department of University Hospital in Olomouc with the diagnosis af acute anterior uveitis. A living parasite has been detected in the anterior chamber in a slit lamp examination. The vitreous and retina remained uninvolved. The acute iridocyclitis associated with parasitic infection is a very rare cause of anterior uveitis in Central Europe. The patient underwent surgical removal of the parasite via paracentesis. The inflammation resolved under the treatment with atropine and dexamethasone drops within a few days. Histopathological examination revealed the parasite as a young larval stage of tapeworm from family Pseudophyllidea (sparganum). Based on the analysis of development cycles of different types of tapeworms and according the literature data on tapeworms found in the Czech Republic genus Spirometra seemed to be the most plausible cause of the patient's disease. As the most probable source of viable parasites authors suspect swallowed water containing tiny infected crustaceans in the dam near the town Olomouc in Moravia.
