Sparganosis is a parasitic infection caused by the plerocercoid tapeworm larva of the genus Spirometra. Although the destination of the larva is often a tissue or muscle in the chest, abdominal wall, extremities, eyes, brain, urinary tract, spinal canal, and scrotum, intramuscular sparganosis is uncommon and therefore is difficult to distinguish from a soft tissue tumor. We report a case of int...

ABSTRACT Infection of Schistocephalus solidus in three-spined stickleback, Gasterosteus aculeatus was investigated for over a two year period from Airthrey Loch, Scotland. Altogether 1301 fishes were sampled. A total of 1327 S. solidus plerocercoid worms were extracted from the visceral cavity of 385 fish. The prevalence was 29.55%, mean intensity (3.44) and abundance (1.01). Monthly prevalenc...

Two types of tetraphyllidean merocercoids, Phyllobothrium delphini and Monorygma grimaldii, are well known from most cetaceans world-wide. The role of cetaceans in the life-cycle of these merocercoids is unclear because their specific identity is as yet unknown. The problem is compounded by poor descriptions of both merocercoids. We used light and scanning electron microscopy, and histological ...

the lernaea parasite was reported in alburnus hohenackeri kessler, 1870, collected from the char-nimeh (or chahnimeh) lake, eastern iran. three fishes were infected with l. intestinalis having 3 to 22 parasites increasing with fish size. the maximum and minimum of parasite lengths were 138.02 mm and 24.54 mm respectively. the prevalence, mean intensity and abundance of infection by plerocercoid...

PURPOSE To present a case of ocular sparoganosis presenting as itching sensation. METHODS A 60-year-old woman presented for removal of an itchy subconjunctival mass in her left eye. Her ocular findings were normal, except for a subconjunctival mass (1.5 x 1.5 mm). RESULTS A parasite excised from the subconjunctival mass was identified as a sparganum, by microscopic examination after hematox...

A 38-year-old Japanese man presented with a 2-year history of cerebellar ataxia, fever, and headaches. MRI revealed migration of the lesion (figure, A–C). CSF cytology showed eosinophilic meningitis (figure, D); serum and CSF ELISA were positive for Spirometra erinaceieuropaei. Human sparganosis is a rare parasitic infection by the larval cestode of Spirometra that results from ingesting the pl...

cases of sparganum mansoni , caused by the plerocercoid larva of the tapeworm s. mansoni , occur through­out the world, particularly in asian, middle eastern, and european countries. however, cases of infection with this parasite are rarely seen in japan. here, we present a case of a 61-year-old woman with a solitary subcutaneous nodule in left inner aspect of the thigh, from which a long, slen...
