Hydatid cyst, the larval stage of Echinococcus spp., is a common parasitic disease in Iran. The liver and the lungs are the most commonly involved organs. Hydatid cysts have also been reported in bones and soft tissues such as muscle, brain tissue, spleen, thyroid and even in the heart. Hydatid cyst of the inguinal area, resembling a hernia is a rarity presenting at an unusual site. A hyper...

Abstract Pineal cysts are prevalent in the population. Due to more widespread use of magnetic resonance imaging, an increasing number symptomatic patients with non-hydrocephalic pineal referred neurologists and neurosurgeons. Currently, there is no generally accepted theoretical framework for linking symptoms a cyst. We have previously suggested that cyst-induced crowding recess may affect veno...

BACKGROUND Primary intracranial hydatid cyst is a rare location of human echinococcosis whose spontaneous, traumatic or even iatrogenic rupture, as in case of misdiagnosis, may cause anaphylactic reactions and dissemination. CASE REPORT We discuss the management of a 9-year-old boy who was admitted to our Emergency Department with an intracranial hypertension syndrome. Head CT scan and brain ...

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...

This study evaluates the antitumor immune response induced by human hydatic cyst fluid (HCF) in an animal model of colon carcinoma. We found that anti-HCF antibodies were able to identify cell surface and intracellular antigens in CT26 colon cancer cells. In prophylactic tumor challenge experiments, HCF vaccination was found to be protective against tumor formation for 40% of the mice (P = 0.01...

Primary Cerebral hydatid cyst (CHD) is absolutely rare phenomenon in Echinococcus infection. Even in the endemic zone CHD is consist of 2% of all intra-cranial space occupying lesions (SOL). We are describing a 7-y-boy from non-endemic area with Primary CHD having no extra cranial echinococcosis presenting right sided hemiparesis, partial seizure and bilateral papilloedema. Computed tomography ...

The authors are presenting here a case of dermoid cyst in 50-year-male who presented with 3 months history of headache.

Brain echinococcosis is the most common brain parasitic infection in the world. It happens in a very rare location, representing 1% to 2% all cases with hydatid disease. It is more common by approximately 50–70% in pediatric population and young adultswith a male predominance. The definite hosts of echinococcus are various carnivores; man is an accidental host. The growth of hydatid cysts is us...

We describe a case of 16-year-old girl who reported with diminution of vision in left eye for past seven months with appearance of white reflex. Slit lamp biomicroscopy revealed the presence of a live grayish white cyst in the anterior chamber. The ultrabiomicroscopic evaluation revealed a large live Cysticercus cellulosae cyst in anterior chamber. The CT-scan of the brain revealed multiple non...

A 28-year-old woman presented with a rare case of endodermal cyst located ventral to the lower brain stem manifesting as recurrent aseptic meningitis. Computed tomography and magnetic resonance imaging demonstrated a cystic mass located ventral to the lower brain stem and extending from the prepontine to the upper cervical (C-2) cistern. The lesion was totally removed through a retrosigmoid cra...
