echinococcosis, although eradicated in many countries, is still widespread in communities where agriculture is dominant. cystic hydatidosis is a significant public health problem in the regions with endemic echinococcosis. the hydatid cysts tend to form in the liver or lung, but may also be found in other organs of the body such as brain, heart, and bone, while thyroid gland involvement is rath...

objectives: toxoplasma gondii is a coccidian protozoon which forms tissue cyst in different organs of infected intermediate host. the present study was conducted to demonstrate the active form of parasite in different tissues of rat, which was experimentally infected with rh strain of toxoplasma gondii using bioassay method inmice. materials & methods: in the experimental assay, 75 rats an...

Cysteine is known to cause neuronal cell death and has been reported to be elevated in brain ischemia, but it has not been studied in clinical stroke. In this study, we correlated plasma levels of cyst(e)ine with long-term clinical outcome at 3 months in acute stroke. Patients were classified into 3 groups at 3 months as follows: good outcome (Rankin 0-1, n = 11), poor outcome (Rankin 2-5, n = ...

objective(s):there are supportive evidences about the possible role of latent toxoplasma. gondii infections on the behavior and neurologic functions, such as increased dopamine levels in the brain. the aim of this study was to examine anti-toxoplasma activity of aripiprazole that is an atypical anti-psychotic drug in mice. materials and methods: mice were randomly divided into four groups, incl...

Acute bleeding within a colloid cyst of the third ventricle represents a rare event causing sudden increase in the cyst volume that may lead to acute hydrocephalus and rapid neurological deterioration. We report a case of spontaneous rupture of haemorrhagic third ventricular colloid cyst and its management. A 77-year-old ex-smoker presented with unsteady gait, incontinence and gradually worseni...

a hydatid cyst is a zoonotic infection caused by the larval forms of mostly the echinococcus granulosus. in humans, the most common site of cyst development is the liver (60%), followed by the lungs (20%), and much less commonly in other organs such as kidney, spleen, brain, and other soft tissues. the localization of cysts in muscles and subcutaneous is very rare. we report a case of 38-year-o...

Ten consecutive patients with arachnoid cysts in the middle cranial fossa, diagnosed by CT, were studied. They were divided into three clinical groups: (1) four patients with progressive symptoms caused by secondary bleeding, (2) five patients with non-progressive symptoms of headache or epilepsy, and (3) one asymptomatic patient. The nine symptomatic patients were operated upon and eight showe...

Multiple cerebral hydatid cysts are rare and usually occur as a result of spontaneous, traumatic, or surgical rupture of a primary hydatid cyst (1]. Surgical treatment of multiple cysts involves a greater ri sk than treatment of a single cyst because of the increased risk of cyst rupture. We report the use of nonionic CT ventriculography for the preoperative examination of a patient with multip...

The aim of this study was to determine the prevalence of hydatidosis in Lorestan province during a 10 year period (2005-2014). We surveyed medical records of infected patients with hydatid cyst who had been operated in referral hospitals of Lorestan province, Iran. Several parameters were analyzed including age, gender, place of residency, hospitalization time, and the location of cysts. Cystic...

Background Cerebral hydatid cyst is a rare condition even in endemic parts of the world, which usually happens in children. Huge cysts are usually presented with neurological deficits and symptoms of increased intracranial pressure. Here, we present the case of a five-year-old child with solitary huge cerebral cyst. <sp...
