Isolated foot drop due to a brain lesion is rare. A 48-year-old man complained of inability to dorsiflex the right foot. Right dorsiflexion had 0/5 muscle strength and there were no upper neuron findings on his neurological examination. Magnetic resonance imaging of the brain revealed a left parasagittal brain mass. The lesion was removed and muscle(More)
We report 2 patients with suprasellar haemangioblastoma (HBL). The first, a 54-year-old man, presented with headache and gradually worsening bilateral visual field defects that had progressed to complete blindness on the right side. Computed tomography (CT) and magnetic resonance imaging (MRI) of the brain demonstrated a suprasellar mass. The mass was(More)
Intraspinal gas can be observed in a number of pathological settings including degenerative disc disease, infection, tumor or trauma, and in patients who have undergone therapeutic and diagnostic procedures. The air can be epidural, intradural or intradiscal. Intraspinal gas is usually asymptomatic. We report intraspinal gas in three patients, one with(More)
The aim of this study was to evaluate how timing of irradiation after brain surgery in rats relates to overall extent of brain radiation damage. Extent of injury was determined according to lipid peroxidation (malondialdehyde; MDA) levels in brain tissue. Thirty female rats were randomly assigned to five equal groups (Groups A-E). Four groups underwent(More)
of tumor growth leading to large tumor sizes at the time of diagnosis (8,33,41). The differentiation from meningiomas of the planum sphenoidale and tuberculum sellae is of clinical and surgical importance; tumors arising from these sites are usually diagnosed at an early stage due to visual impairment, which is a late finding in OGMs (7,11,22,28).(More)
Schwannomas are encapsulated, benign tumors, which generally originate from the schwann cells on cranial or peripheral nerves. Malignant transformation into neurofibrosarcoma occurs in 1% of these tumors. While schwannomas account for 8% of all central nervous system tumors, intracerebral schwannomas occurring independent from cranial nerves are extremely(More)
The spinal pain syndrome appears in cosmonauts on both short and long-duration missions. This untoward factor may affect body systems functioning and complicate the successful accomplishment of space mission. Purpose of the investigation was to examine the lumbar spine and to elucidate whether its condition relates to the spinal pain development and changes(More)
Suprasellar located ectopic pituitary adenomas are unusual tumors. We report a rare case of suprasellar prolactinoma arising from the pars tuberalis in a 37-year-old woman. Menstrual disregulation and bitemporal hemianopsia were the main complaints. Blood tests revealed hyperprolactinemia. In magnetic resonance the tumor was totally supradiaphragmatic.(More)
