[Diagnostic value of the CSF uric acid level (author's transl)]. 1978

S Tsunoda, and A Gega, and S Utsumi, and Y Matsuoka, and C Kubota

Uric acid is the end-product of purine metabolism, and purines are the nitrogenous bases derived from the breakdown of nucleic acids. The CSF uric acid level is thought to be the index of the turnover of the nucleic acid and the degree of the cellular destruction in the brain. CSF uric acid levels were investigated in normal controls (30 cases) and in patients with brain tumor (20 cases), microcephalus (8 cases) and craniostenosis (4 cases). The mean values and standard deviations of CSF uric acid levels in normal controls were as follows; Newborn--9 yrs 0.34 +/- 0.09 mg/dl; 10 yrs--19 yrs 0.50 +/- 0.18 mg/dl; 20 yrs--29 yrs 0.46 +/- 0.05 mg/dl; 30 yrs--39 yrs 0.35 +/- 0.10 mg/dl; 40 yrs--49 yrs 0.35 +/- 0.23 mg/dl. Thereafter 0.72 +/- 0.21 mg/dl. The increased CSF uric acid levels after the age of 50 is thought to be due to the cellular destruction in the brain. CSF uric acid levels increased in patients with highly malignant brain tumor such as grade 3 or 4 astrocytoma and sarcomatous meningioma, but were normal in patients with grade 2 astrocytoma and meningiomas of meingothelial or fibroblastic type. CSF uric acid levels decreased in patients with microcephalus, but were almost normal in patients with craniostenosis. There is a significant correlation between CSF uric acid levels and the degree of brain atrophy in infants.

D007223	Infant	A child between 1 and 23 months of age.	Infants
D008297	Male		Males
D008527	Medulloblastoma	A malignant neoplasm that may be classified either as a glioma or as a primitive neuroectodermal tumor of childhood (see NEUROECTODERMAL TUMOR, PRIMITIVE). The tumor occurs most frequently in the first decade of life with the most typical location being the cerebellar vermis. Histologic features include a high degree of cellularity, frequent mitotic figures, and a tendency for the cells to organize into sheets or form rosettes. Medulloblastoma have a high propensity to spread throughout the craniospinal intradural axis.

D008579	Meningioma	A relatively common neoplasm of the CENTRAL NERVOUS SYSTEM that arises from arachnoidal cells. The majority are well differentiated vascular tumors which grow slowly and have a low potential to be invasive, although malignant subtypes occur. Meningiomas have a predilection to arise from the parasagittal region, cerebral convexity, sphenoidal ridge, olfactory groove, and SPINAL CANAL.

D001932	Brain Neoplasms	Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
