Pelvic osteosarcomas causing lumbosacral nerve root compression presenting as herniated intervertebral disc: report of two cases.

Osteosarcomas of the pelvic bone are rare. Neurological complication of osteosarcomas in this location is also rare. Diagnosis is not always easy, and misdiagnosis may occur due to pelvic bone destruction and nerve root compression. We present two cases of pelvic osteosarcoma with lumbosacral radicular symptoms who were previously thought to have lumbosacral herniated intervertebral disc.

An unusual case of cephalocele associated with lipoma of corpus callosum.

Cephalocele is a part of the family of neural tube defects. Although the frequency has ranged from 1 per 2,400 to 1 per 12,500 live births, the true incidence has been hidden in stillborns, underreferral of massive defects and early pregnancy losses. It has been suggested that the size, the content of the sac and associated hydrocephalus were unfavorable factors for the prognosis. Cephaloceles may occur as isolated malformations or together with other anomalies, and associated abnormalities are present in up to 50% of the cases. We report an unusual case of encephalocele associated with lipoma of corpus callosum, and the features of magnetic resonance imaging are discussed.

Prognostic value of serum neuron-specific enolase levels after head injury.

Neuron-specific enolase (NSE) is a dimeric cytoplasmic enzyme detected in high levels in neurons and acts in the glycolytic pathway. It is known that there is a quantitative relationship between the concentration of serum NSE and the degree of cell damage in the central nervous system. We examined serum levels of NSE by enzyme immunoassay in 89 patients with head injury and aimed to evaluate its relationship with neurological status and prognosis of the patients.

Choroid plexus papillomas of the posterior fossa: extraventricular extension, intraventricular and primary extraventricular location. Report of four cases.

Four cases of Choroid Plexus Papilloma (CPP) of the posterior fossa are presented. Two cases had extraventricular extension from the fourth ventricle to the Cerebellopontine Angle (CPA) through the foramen of Luschka, in one the CPP was located primarily in the CPA and the fourth case was only in the fourth ventricle. CPP are rare tumours of the Central Nervous System and primary extraventricular location is extremely rare. We know that primary location in the extraventricular and intraventricular regions and extraventricular extension have different pathological mechanisms. The main purpose of this paper is to discuss and review some possible explanations for these mechanisms.
