OBJECTIVE
To differentiate diagnostic and prognostic factors from the clinical material of patients with cerebral sparganosis in central South China.
METHODS
Consecutive patients with cerebral sparganosis from our hospital between 2010 and 2018 were retrospectively enrolled. The clinical manifestations, radiographic features, treatment, and outcomes of these patients were analyzed.
RESULTS
Thirty patients with cerebral sparganosis were included, and foci migration on magnetic resonance imaging was detected in 22 patients, from whom we observed 4 migration modes: interlobar migration (50.0%, 11/22); transmidline migration (27.3%, 6/22); transventricular migration (13.6%, 3/22); and cerebellum-brainstem migration (9.1%, 2/22). The percentage of good outcomes was higher in patients with live worm capture than in those without live worm capture (75.0%, 12/16 vs 33.3%, 2/6). Exposure to preoperative antiparasitic medication was associated with worm migration toward the cortical surface, which led to a higher probability of live worm capture.
CONCLUSIONS
We propose 4 modes of sparganosis migration that are correlated with worm capture and neurologic prognosis. We found that exposure to antiparasitic medication was associated with worm migration toward the cortical surface, leading to a higher probability of live worm capture. These observations suggest a novel significance for preoperative medication of cerebral sparganosis.

Review
BACKGROUND
Sparganosis is an important parasitic disease in Guangzhou and is mainly acquired through the consumption of frog meat or contact with fresh frogs infected by larval stages (spargana) of the tapeworm species Spirometra mansoni.
METHODS
In this study, the prevalence of intestinal S. mansoni infections (with adult parasites) in dogs and cats and of extraintestinal S. mansoni infections (with spargana) in frogs was assessed. In addition, a questionnaire survey was carried out among residents in Guangzhou City in order to evaluate their awareness about the medical and epidemiological relevance of Spirometra and sparganosis.
RESULTS
In total, the feces of 229 dogs and 116 cats were examined for eggs, and 1949 frogs were examined for spargana. Sixty-three dogs (27.5%) and 47 cats (40.5%) had eggs in their feces. Two hundred and sixteen out of 416 wild Rana tigrina rugulosa Wiegmann frogs examined were sparganum-positive, with an infection rate of 51.9%, while the infection rate in Rana limnocharis Boie was 35.1% (13/37). None of the tested farmed frogs (including R. tigrina rugulosa and Rana catesbeiana) was positive (0/1382). Analysis of the questionnaire revealed the following results: (1) about 41.0% of residents in Guangzhou had some knowledge of sparganosis or sparganum infection, and information in TV programs was the most important way that residents learned about sparganosis. (2) About 59.9% of the residents ate frog meat. Eating the meat, viscera, or blood of animals, e.g., frogs, snakes, pigs, chicken, mice, and birds, in an improper way might be the main means by which residents acquire the infection. (3) The risk of sparganum infection was higher in males than in females.
CONCLUSIONS
A high sparganum infection rate was observed in the wild frogs sold in agricultural product markets in Guangzhou. The infection was also serious in cats and dogs in Guangdong Province. With lifestyles and eating habits resulting in sparganum infection, it is necessary to focus on market management and community education in order to prevent the transmission of this disease in Guangzhou.

Cerebral sparganosis is a rare parasitic infection that can be difficult to diagnose due to similarities in clinical and imaging features with more common parasitic infections, such as neurocysticercosis, and other neurologic conditions. We present a case of a 61-year-old female with a verified case of cerebral sparganosis. We also review the current literature regarding the sparganosis infection process, imaging features, and unique therapeutic options. With awareness of the risk factors for cerebral sparganosis and consideration for this diagnosis when the response to therapy for other organisms appears suboptimal, the time to accurate diagnosis may be reduced, and treatment outcomes improved.

A 57-year-old Korean female patient presented with a migrated palpable left breast mass. Physical examination revealed a 3-cm soft, non-tender mass in the upper inner quadrant of her left breast. Mammography showed 8.2-cm extended nodular and tortuous tubular masses in the upper portion of her left breast. Ultrasonography revealed a 5.8-cm extended nodular, tortuous tubular and hypoechoic to anechoic lesion in the subcutaneous mammary parenchymal layer. A lumpectomy was conducted and revealed a 30-cm live tapeworm. Histopathologic examination of the excised breast tissue revealed chronic granulomatous inflammation and eosinophilic infiltration by a parasitic organism, which was confirmed as a sparganum. After surgery, the patient was treated with a single dose of praziquantel and albendazole. Asian countries such as Korea, China and Japan are known to have high endemicity of sparganosis, mostly because of their dietary customs. When examining patients from these countries, sparganosis should be considered because of the unique dietary customs despite the high level of hygiene.

Review
BACKGROUND
Sparganosis is a zoonosis that occurs occasionally in humans. The infection is reported in many countries but is most common in eastern Asia. In Thailand, a southeast Asian country, the infection is sporadic.
DESIGN
In this study the clinical presentations of human sparganosis cases in Thailand were investigated by means of a literature review.
RESULTS
Reports of 34 cases of sparganosis were found. The infections were ocular (17 cases), subcutaneous (ten cases), central nervous system (five cases), auricular (one case), pulmonary (one case), intraosseous (one case) and intraperitoneal (one case). Of these 34 cases, 14 had risk behaviour reported, 12 had a history of drinking impure water, five had a history of eating frog or snake meat and two had a history of using frog or snake meat as a poultice. Some cases had more than one risk factor.
CONCLUSION
Most cases of sparganosis in Thailand presented with superficial ocular mass lesions. The major risk behaviour in Thailand is drinking water contaminated with the infective organism. Some cases of serious deep visceral sparganosis have also been reported.

Review
Humans are known to serve as the secondary intermediate host for some larval forms of canine or feline tapeworms. Sparganosis is caused by plerocercoid larva of Spirometra of which there are three main species; Spirometra mansoni (or Spirometra erinaceieuropaei), Spirometra mansonoides and Spirometra proliferum. A one-and-half-year-old patient presenting with febrile illness was diagnosed radiologically as a case of liver abscess. The aspirate from the abscess cavity had a thin thread-like worm which was identified as a larval stage of Pseudophyllidea that was further confirmed as belonging to genus Spirometra. Aspiration of the worm and antiparasitic therapy with metronidazole led to complete recovery. Reports of sparganosis from Indian subcontinent are scanty and these cases had involvement of brain, kidney and eye. To the best of our knowledge this is the first case of hepatic sparganosis from India.
