Spinal tuberculosis is curable disease, and early diagnosis is mandatory for early treatment. We reviewedconventional radiographies and CT from Histopathologically confirmed 30 cases of spinal tuberculosis, and comparedthese findings with radiologic findings from 2 cases of pyogenic spondylitis and 4 cases of meastasis. The resultswere as follows: 1. The frequnet site of involvement were thoracolumbar juntion and low lumbar vertebrae, and themost frequent type is multisegmented subligamentous type (93.3%). 2. CT was not of great use in the diferentaldiagnosis of the tuberculosis. Dominant CT findings of tuberculous spondylitis were anterior vertebral bodydestruction, paravertebral soft-tissue mass and thick walled abscess formation occasionally containingcalcification and disc space narrowing, in the setting of an indolent or relatively benign course. 3. CT is thebest modality for imaging the extent and anatomy of the destructive process, the degree of canal encroachment, andthe change of adjacent vital structure. So CT was particularily useful in pre-operative planing of debridement andstabilization surgery. 4. The most common causes of neurologic manifestations in tuberculous spondylitis were thecompression of spinal cord by sequestrated bony fragments and disc material, granulation tissue or abscess in thespinal canal.

We retrospectively evaluated the characteristic computed tomographic (CT) findings in nine patients with exohepatic hepatocellular carcinoma(HCC) pathologically prove by surgery(n=2) or percutaneous needle biopsy(n=7). The CT findings of exohepatic HCC were correlated with clinical findings and compared with those of usual HCC Lesions were in the left lobe lobe(n=7) and right lobe(n=2) of the liver. All lesions showed a well-marginated hypodense mass with capsular enhancement on enhanced CT scan. The patterns of capsular enhancement were complete in five and partial in four cases. The portal vein thrombosis was seen only in one case. There was no difference between exohepatic HCC and usual HCC in clinical findings such as increased α-fetoprotein(α-FP), positive Hepatitis B surface antigen(HBsAg), and underlying liver cirrhosis. In conclusion, the CT findings of exohepatic HCC were a well-defined hypodense mass with complete or partial capsular enhancement and these findings may be useful in differentiation from the tumors of adjacent organs.

Left ventricular(LV) diastolic filling is abnormal at rest in many patients with coronary arery disease, even in the presence of normal resting LV systolic function. To determine the effects of improved myocardial perfusion on impaired LV diastolic filling and to detect the most sensitive parameter to assess LV diastolic function, gated radionuclide ventriculography were performed in 14 patients with coronary artery disease before and after successful percutaneous transluminal coronary angioplasty(PTCA). All patients had no previous myocardial infarction and no abnormal wall motion in gated radionuclide and contrast ventriculography. The following results were obtained; 1) There were no significant differences in the parameters of LV systolic function, such as peak ejection rate(PER, time to peak ejection rate(TPER), ejection fraction(EF) after successful PTCA. 2) Peak filling rate(PFR) and time to peak filling rate(TPFR), indexes of LV diastolic function, had no significant changes after successful PTCA. 3) The percent contribution of late diastolic filling to stroke volume(%LDF/SV) decreased from 26.5+/-6.8% to 19.1+/-6.6%(p<0.005 by paired t-test). These data suggest that in many patients with angina and normal LV systolic function, impaired global diastolic filling is a reversible manifestation of impaired coronary flow, and percent contribution of late diastolic filling to stroke volume(%LDF/SV) can be a sensitive parameter to evaluate impaired LV diastolic filling in coronary artery disease.

5.Intradural Lumbar Disc Herniation with Intradural Gas: Report of Three Cases.

This paper reports on three cases of an intradural lumbar disc herniation (IDLDH) that were diagnosed by a radiological examination. In all cases, an intradural vacuum (IDV) was detected on the CT scans, and the IDLDH showed iso- or lower signal intensity on the T2-weighted images. Enhanced MRI of one case revealed a small amount of air, but this was without enhancement. All the cases showed definite IDV on the CT scans, and this was an important clue for diagnosing IDLDH.

Intradural cervical disc herniation is an extremely rare condition and its pathogenesis is not certain. We experienced a case of intradural cervical disc herniation at the C4-5 level in a 56-year-old man. The preoperative sagittal T1- and T2- weighted images revealed an intradural iso-intensity lesion, with the spinal cord behind the posterior longitudinal ligament at the C4-5 disc level. The post-contrast T1-weighted image revealed a peripheral enhanced intradural lesion. We report here on a case of an intradural cervical disc herniation that was diagnosed by radiological examination, and we include a review of the related literature.

Disc fragment migration occurs in 35%-72% of lumbar disc herniations. Most of the herniated disc fragments migrate in the rostal, caudal and lateral directions. Posterior epidural disc fragment migration is a rare finding and posterior migration causing Cauda Equina syndrome is exceptionally rare. We report here on two cases of L4-5 disc fragment posterior epidural migration that caused Cauda Equina syndrome, and this was diagnosed by performing radiological examination, and we also include a review of the related literature.
