[A case of huge diploic epidermoid of the temporal bone with intratumoral hemorrhage].

A case of huge diploic epidermoid which occurred in the right temporal bone and occupied almost all of the middle fossa and a part of the posterior fossa. CT of the tumor showed a low density lesion with multiform isodensity spots and a rim enhancement by CECT. Histologically, multiple old blood clots were recognized in this tumor contents. A review of the literature was made as regards CT findings of diploic epidermoid.

The levels of vasopressin in cerebrospinal fluid of patients with alcoholism.

Concentrations of arginine-vasopressin (AVP) in the cerebrospinal fluid (CSF) of 5 alcoholic patients and 6 healthy volunteers were determined by a radioimmunoassay. The concentrations of AVP in the CSF of alcoholic patients were 2.93-6.17 pg/ml (the mean value, 4.80 +/- 1.34 pg/ml) and those of healthy volunteers 3.80-12.59 pg/ml (the mean value, 9.87 +/- 3.19 pg/ml). The AVP level in the CSF of alcoholics was significantly lower than that of normals (P less than 0.02).

[Transfer of fosfomycin into the cerebrospinal fluid].

After the fosfomycin (FOM) infusion, its levels in serum and cerebrospinal fluid (CSF) were repeatedly measured in 8 cases without meningitis. 1. The peak concentration of FOM in CSF was 15.5 micrograms/ml with the average of 10.3 micrograms/ml and was reached at 240 minutes with the average of 210 minutes after the infusion. The biological half life time of FOM in CSF was 2 to 6.5 hours. 2. The peak concentration in CSF was compared with it in serum. The average ratio was 4.3 per cent. Each area under the curve (AUC) of FOM concentration in CSF and serum was calculated and average of their ratio was 9.0 per cent. 3. In a case with middle cerebral artery aneurysm, FOM transferred into CSF with ease. The lowest diffusion into the CSF was shown in 2 cases of meningioma. In 3 cases of hypertensive intracerebral hemorrhage with intraventricular perforation, FOM moderately transferred into CSF.
