OBJECTIVE To determine whether central periodic breathing (CPB) is associated with acute involvement of any particular part of the brain, or the extent of total damage in patients with acute stroke. METHODS CPB was identified using portable monitoring equipment in patients with stroke on admission. A neuroradiologist classified acute stroke lesions and prior cerebrovascular disease on brain i...

BACKGROUND Brain abscess in young infants is extremely rare and usually associated with a previous history of bacterial meningitis or septicemia. CASE PRESENTATION Here we report a cerebellar abscess mimicking brain tumor with atypical clinical and paraclinical presentations. A two-month old previously well-baby boy was referred to us with persistent vomiting, strabismus and developmental reg...

A 67-year-old male presented with left temporal hemianopsia and left hemiparesis. A contrast-enhanced magnetic resonance image revealed a 4.5×3.5×5.0 cm rim-enhancing mass with central necrosis and associated edema located in the left occipital lobe. Of positron emission tomography and abdominal computed tomography, a 9-cm mass with poor enhancement was found in the right hepatic lobe. Cranioto...

THis cross-sectional study was performed on 382 patients with depressed skull fracture admitted to the neurosurgery ward of Kerman Bahonar Haspital between 1994 and 1999.329 of the patients(86.1%) had open fractures,while the  fracture was of closed type in 53 cases (13.9%).of those with open fracture,42%were associated with dura tearing ,whereas the rate was 34% in closed fractures.the most co...

lnflammatory pseudotumor (IPT) is a rare, non-neoplastic inflammatory process. It is most commonly occurs in the orbit, but extension into brain parenchyma is uncommon. In a confirmed case of IPT, most cases show good improvement with steroid theraphy. A 50-year-old man with progressive left-eye visual disturbance and mass lesion was admitted in a hospital. A left orbital mass biopsy revealed w...

A three-year-old neutered male toy fox terrier presented for a Chiari-like malformation. No neurological deficits were found on examination, although diffuse cervical, thoracolumbar and head pain were present. A mass within the fourth ventricle was apparent on magnetic resonance imaging (MRI) of the brain. The lesion was hyperintense to brain parenchyma on T2-weighted images, hypointense on T1-...

We aimed to evaluate the clinical and pathologic features of two common medical illnesses and their appropriate workup and pathognomonic findings. A 57-year-old white male presented with a new onset expressive aphasia while traveling abroad. He was evaluated at an outside facility and underwent workup for a stroke. The evaluation included a CT and MRI of the brain demonstrating three new enhanc...
