The gold standard for final diagnosis is histopathology in which typical cysts with scolices
and hooklets are diagnostic.
are contained within the inner layer and daughter cysts may be seen floating in clear fluid within the cyst.
Tapeworms, either with scolices
or without scolices
, were expelled from 24 persons with taeniasis after the persons received 2 g of niclosamide or 40 mg/kg of praziquantel and a purgative.
If stabilization with pedicle screws is performed, the surgeon should be aware that theoretically the disease may be iatrogenically seeded into the vertebral bodies if viable scolices
are present at the time when the pedicles are probed before inserting the screws.
The cyst is filled with clear fluid and contains free scolices
and brood capsules.
FLAIR images detect a significantly higher number of scolices
than other sequence, which is helpful for diagnosis of NCC.
The cerebral coenuri in sheep could reach 95 cm in size and could contain up to 700 scolices
(Boev et al.
To our surprise, we found the cytology smears contained characteristic parasitic elements such as scolices
, hooklets, homogeneous eosinophilic-laminated membrane [Figure 1], and calcospherules; a diagnosis of hydatid cyst in parotid gland was made.
Biopsy is generally considered to be contraindicated in echinococcosis owing to fear of dissemination of scolices
and other potentially fatal acute anaphylactic reactions.
In patients originating from endemic areas such as South America, Africa, and Asia, a careful search for the characteristic larval forms and scolices
should be made.
Primary intradural extramedullary hydatid cysts are very rare and most often solitary, (13,25) secondary involvement of the intradural space may result from a ruptured IC cyst and subarachnoid spread of scolices
or from a dural tear during operation or lumbar puncture.
Coenurus cysts with multiple scolices
recorded from brain and spinal cord of sheep and goat have been identified as Coenurus cerebralis, while those from connective tissues and visceral organs are considered as C.
