Cases of metastases from extracranial tumor to intracranial tumor are very rare. The world wide review of the literatures until 1992 revealed 44 cases of primary intracranial tumors containing metastatic tumors which are unrelated extracranial primary malignant tumors; the intracranial recipient tumor is a meningioma in 35 cases among them. Carcinomas of the lung and the breast are the most common extracranial donor tumors. Metastases from colon cancer to meningioma are extremely rare. A 74 year-old-female presented with headache for 2 weeks. CT revealed a round mass with high signal intensity, measuring 4 cm in diameter, which is located in the left parietal lobe. The patient had colon cancer 2 years ago and lymphoma I year ago. On operation, the tumor is relatively well delineated and attached to the meninx. Microscopically, the tumor is composed of fascicles of long slender, fibroblast-like spindle cells with indistinct cytoplasmic border, variable amount of collagen deposit and many psammoma bodies. A few scattered glands are present in periphery of the meningioma. The tumor glands are composed of columnar cells with basally located hyperchromatic nuclei and similiar to the glands of the adenocarcinoma of the colon.

In the diagnosis of acute spinal trauma, meticulous physical examination and history taking is the most important tool and auxilliary support support can be given by plain X-ray, CT or myelography, etc. But these cannot show the state of cord injury directly. On the contrary, MRI shows the cord directly as well as the soft and bony tissues. We analysed retrospectively 39 patients who suffered from acute spinal trauma at the level of cervical and thoracic spine and had their spine MRI taken. We verified the meaningful correlation between the signal change in the spinal cord on MRI and the degree of neurologic deficit and prognosis, using Frankel classification and trauma motor index at the time of admission and the final follow-up.

The study was undertaken to evaluate the effect of major blood components on the CT number. The CT numbers according to the various levels of hematocrit, total protein and cholesterol were checked and analysed by the dilution of pack cell, plasma and 184 complete blood cell count samples under same scanning conditions. In case of normal protein and cholesterol level(33 samples), the CT number was increased about 5.5 hounsfield unit according to 10% increase of hematocrit level: and In case of normal hematocrit and cholesterol level(39 samles), the CT number was increased about 3.5 hounsfield unit according to 1gm% increase of protein level. CT number changes were not predictable according to the changes of cholesterol level(34 samples). From these results, we concluded that major blood components should be considered in the CT number analysis of tissue.

From February 1996 to May 1997, 18 patients underwent mitral valve repair for mitral regurgitation. There were 9 male and 9 female patients aged from 19 to 68 years (mean, 53). Thirteen patients were in New York Heart Association (NYHA) class III and IV. The cause of mitral regurgitation was degenerative in 12 patients, rheumatic in 5 patients and infective in 1 patient. Fifteen patients were in Carpentier's functional classification II, 2 patients in Carpentier's class III and 1 patient in Carpentier's class I. Surgical procedures included prosthetic ring annuloplasty (16 cases), rectangular resection of posterior leaflet (15 cases), chordal shortening (5 cases), triangular resection of anterior leaflet (2 cases), commissurotomy (2 cases), partial transposition of posterior leaflet (1 case). These procedures were combined in most patients. There was no operative death. These patients have been followed from 1 to 15 months, mean of 6.7 months. There was one late death resulted from low cardiac output following mitral valve replacement. The function of the repaired valve in other 17 patients has remained satisfactory during the observed interval. We consider that mitral valve repair is highly satisfactory in patients with mitral regurgitation.
