showing the lack of a rostellar hook crown in the middle of the scolex
, which is a synapomorphy in T.
F) Histological view of a scolex
of the larva, transversal cut (200 [micro]m).
It has be postulated that the hydatid scolex
gains access to the pelvis by the lymphatic or haematogenous route [15, 16].
14 gracilis (plerocercoid) ZUEC-PLA 42 Scolex
pleuronectis 86 0-182 20 [+ or -] 30.
The indirect hemagglutination tests was negative, he underwent surgical resection through Suboccipital-retrosigmoid approach, intraoperative views showing two cystic masses with white cystic content, the cysts were broken and the cysts'membrane with scolex
were removed smoothly which were not adherent to cerebellar parenchyma very much.
The diagnosis of IVNCC is based on clinical presentation, Magnetic Resonance Imaging (MRI) evidence of cystic lesions containing the scolex
and isolating the parasite histologically from the brain lesions or the CSF.
It is unlikely for a neurocysticercosis ring to have more than 20 mm size, midline shift, irregular thick outline (>20mm) and an absence of scolex
in MRI (4-6).
4,8) The adult worms reside in the small intestines of the host, attached by their armed scolex
, and produce proglottids.
18 gracilis (plerocercoid) Scolex
polymorphus 65 1-832 60.
In a minority of cases, a scolex
(small, eccentric internal speck of enhancement or calcification within the cyst) may be visualised.
Ultrastructure of the scolex
and tentacles of the metacestode of Polypocephalus species (Cestoda: Lecanicephalidae) from the blue-swimmer crab Portunus pelagicus.
These cases required using treating-diagnostic bronchoscopy with following microscopy of broncholavage fluid, sputum and punctate of the pleural cavity to determine echinococcal scolex
hooks and fragments of chitinous surface.
