Some incidental findings on cranial imaging may render every one speechless. Brain plasticity in childhood and slow expansion of arachnoid cyst may be possible explanations of the discordance between the clinical and radiological findings. Here, we presented an asymptomatic, incidentally detected arachnoid cyst accompanied by compression of most parts of brain, displacing the motor cortex to th...

Introduction: Toxoplasmosis is a widely prevalent zoonotic disease, caused by T. gondii. Chickens, consumed widely in many countries, are considered as one of the most important hosts in the epidemiology of T. gondii infection because they could be a main source of infection for both cats and humans. There was no information regarding T. gondii infection in chickens in this area, therefore, thi...

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...

As far as we know, cyst formation in intracranial melanoma is rare, and only 15 cases of intracranial amelanotic melanoma have been reported until now. A yellowish mass was observed in the frontal lobe. The content of the cyst consisted of old hematoma, xanthochromic fluid and necrotic tissue, was evacuated and the cyst wall was totally resected. No abnormal pigmentation was noted in the cyst w...

Supratentorial dermoid cysts are uncommon to develop in the cavernous sinus. We present a ruptured dermoid cyst of the cavernous sinus extending into the posterior fossa. The patient was a 32-year-old female who complained occipital headache, blurred vision, and tinnitus over 4 years. Brain magnetic resonance (MR) imaging revealed an enhanced tumor in the right cavernous sinus extending into th...

BACKGROUND Escherichia coli (E. coli) is the most common causative bacteria of neonatal meningitis, but hematogenous intracranial E. coli infection is rare in adults. Moreover, intracranial abscess formation owing to E. coli, including brain abscesses and subdural empyema formation, is extremely rare. We herein present a case involving a patient with a brain abscess owing to E. coli following a...

Epidermoid cyst. c. Pineal cyst. d. Germ cell tumor. Answers: a. Sorry, arachnoid cysts will follow CSF signal on all sequences. Please pay particular attention to the FLAIR sequence. b. Good try; an epidermoid ...

objective: torticollis is a symptom that can be related to different pathological mechanisms ranging from simple to life-threatening conditions. here we report a child with torticollis caused by a neuroenteric cyst in the upper cervical region; this is a very rare condition in childhood and  in this case, it was successfully resolved by surgery. clinical presentation: a 2.5 year old boy present...

hydatid disease is the most common infections worldwide, but it rarely involves multiple organs. herein, a 12-year-old boy is presented, who was admitted to children's medical center, tehran university of medical sciences, tehran, iran with symptoms of irritability, sleepless, and weak­ness of the extremities. patient's brain computed tomography (ct) scan with contrast media showed large multil...

The protozoan intracellular parasite Toxoplasma gondii forms latent cysts in the central nervous system (CNS) and persists for the lifetime of the host. This cyst is cloaked with a glycosylated structure called the cyst wall. Previously, we demonstrated that a mucin-like glycoprotein, CST1, localizes to the cyst wall and confers structural rigidity on brain cysts in a mucin-like domain-dependen...
