BACKGROUND In Brazil, about two million people living in rural semiarid regions were benefited with the construction of rainwater cement cisterns, as an initiative from the program "One Million Cisterns" (P1MC). Nevertheless, few epidemiological studies have been conducted to assess health risks or protection effects associated with consumption of this water source. The aim of this study was to...

The authors report a case of a ruptured saccular aneurysm located on the posterior temporal artery branched from the fetal posterior cerebral artery. This site of aneurysmal origin is extremely rare. The aneurysmal neck clipping successfully performed via a middle subtemporal route. Key w01·ds: Cerebral aneurysm, Subarachnoidal hemorrhage, Posterior cerebral artery Posterior cerebral artery (PC...

A new percutaneous treatment of tic douloureux has been developed . Transovale injection of glycerol into the retrogasserian trigeminal fibers in Meckel cave results in complete pain relief in 77%-89% of patients [1-3]. The major advantages of percutaneous retrogasserian glycerol rhizotomy include simplicity, radiograph ic confirmation of accurate need le placement, and a much reduced incidence...

Endolymphatic sac tumors are aggressive papillary tumors of the temporal bone that could be associated with von Hippel-Lindau disease (VHL). We present imaging findings of a VHL family with two cases of endolymphatic sac tumors. These tumors spread to the cerebellum and the cerebellopontine cistern and may mimic more frequent tumors of this region. They show predominantly high signals on T1and ...

Torsional nystagmus was noted in a patient with hypothalamic hamartoma. Magnetic resonance imaging revealed an exophytic hypothalamic mass extending into the pre-pontine cistern and abutting ventral mesencephalon. The quickphase of the torsional nystagmus was directed towards the left side, ipsilateral to the side of compression by the hamartoma. Ipsi-lesionally directed pure torsional nystagmu...

Duplex collecting system is a congenital genitourinary anomaly commonly found incidentally. Our experience with a duplex system associated with giant hydroureter presenting as mobile abdominal swelling that was noticed from birth, constipation, and failure to thrive is described. Ultrasound and IVU did not assist in making the diagnosis, while a barium enema suggested a colonic duplication. Con...

We present a case of oculomotor palsy due to hypertensive hemorrhage in the caudate nucleus, with intraventricular extension. To our knowledge, this is the only instance of this complication occurring due to hypertensive hemorrhage. Our patient initially developed headache at the time of her hemorrhage; 8 days later, she developed complete third nerve palsy, which showed improvement at follow-u...

Rathke's cleft cyst is a benign lesion of embryological origin with sellarsuprasellar localization. It is found in 12-33% of normal pituitary glands in autopsy series. Although it is mostly asymptomatic, it can cause symptoms by compressing surrounding neural and pituitary tissues. The most common symptoms are endocrine problems, visual problems and headache. Uncommonly, the lesion can present ...

Suprasellar tuberculomas are exceptionally rare. We present the case of a middle aged male who presented with generalised apathy and meningism of two weeks duration. Neuroimaging was suggestive of tuberculomas in suprasellar cistern, while endocrinological investigation showed panhypopituitarism manifesting as pituitary hypothyroidism, hypocortisolism, and hyperprolactinemia. Cerebrospinal flui...

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...
