Intact protoscolices and hooklets in cytospin preparation of intra‐operative cyst fluid allow rapid confirmation of rare cerebral intraventricular hydatid infestation

Fine needle aspiration cytology diagnosis of an ocular hydatid cyst

“…Immediate diagnosis in this way requires a clinical suspicion of the diagnosis as well as the attendance of a cytologist. 4 Aspiration of hydatid cysts is now thought to be a useful procedure and, furthermore, allows enucleation to be performed safely because the diagnosis is known pre-operatively. 5 Cytological findings in aspiration hydatid fluid show classic cytomorphology and allow an unquestionable diagnosis.…”

“…5 Cytological findings in aspiration hydatid fluid show classic cytomorphology and allow an unquestionable diagnosis. [4][5][6] The fluid aspirated from a hydatid cyst is usually clear and contains debris, a few inflammatory cells and numerous scolices. In old cysts, the scolices may be difficult to find in FNA preparations, but hooklets in a ring-like arrangement remain.…”

“…The finding of hooklets or scolices is diagnostic of hydatid disease. [4][5][6] Although albendazole (which is considered as the preferred medical treatment because of improved intestinal absorption and lower dosage) is used in extraocular infection, it also decreases orbital cyst size and is useful pre-and postoperatively. 5,6 Intraoperative cytological evaluation of any cystic mass is a rapid, reliable method for the diagnosis of hydatid disease.…”
