The radiological findings of various cervical spine fractures were analized on the basis of J.Harrisclassification. It appears to be important for the radiologist to be familiar with radiographic findings ofcervical spine fractures, particularly those of unstable fractures which can result in serious medical problems ifimproperly handled in the department of radiology. 68 cases of cervial spine fracures were analized. The resultsare as follows; 1. Stable and unstable fracures were about equal in incedence. 2. Anterior subluxation accountsfor 43.4% of stable fractures, 19% of all fractures. 3. Bilateral interfacetal dislocation accounts for 51.1% ofunstable fractures, 255 of all fractures. 4. Associated fracture were involved in skull, scapula, mandible andfemur. 5. About 80% of the patients is in third through fifth decade.

We have analyzed utrasonographic finding of 55 cases of hydronephrosis and 34 cases of renal maasses. The results are as follows; 1. 55 cases of hydronephrosis revealed renal enlargement in 55 cases, separation of central echo complex in 27 cases, multiple anechoic areas radiating from the center in 25 cases and dilated renalpelvis in 24 cases. 2. Among the renal masses in 34 cases, simple renal cyst were 15 cases, polycystic kidney in 8 cases, hypernephroma in 8 cases, Wilms' tmor in 2 cases and angiomyolipoma in 1 case. 3. Simple renal cystrevealed single in 14 cases (93%) and well defined anechoic mass with posterior enhancement in all cases. 4. Polycystic kidney revealed bilateral irregular shaped renal enlargement and multiple anechoic cysts throughout the kidney. 2 cases (25%) involved liver. 5. 6 cases (75%) of hypernephroma revealed ill defined modarately echogenicmass without posterior enhancement. 6. All cases of Wilms' tumor revealed well defined large mixed echogenic massin right kidney. 7. Angiomyolipoma revealed bilateral dense echogenic mass with large hemorrhagic cyst in rightkidney. 8. The ultrasonography is useful noninvasive diagnostic modality of evaluation of renal masses and hydronephrosis.

Hemifacial spasm (HFS) is almost always induced by vascular compression but in some cases the cause of HFS are tumors at cerebellopontine angle (CPA) or vascular malformations. We present a rare case of hemifacial spasm caused by epidermoid tumors and the possible pathogenesis of HFS is discussed. A 36-year-old female patient presented with a 27-month history of progressive involuntary facial twitching and had been treated with acupuncture and herb medication. On imaging study, a mass lesion was seen at right CPA. Microvascular decompression combined with mass removal was undertaken through retrosigmoid approach. The lesion was avascular mass and diagnosed with an epidermoid tumor pathologically. Eventually, we found a offending vessel (AICA : anterior inferior cerebellar artery) compressing facial nerve root exit zone (REZ). In case of HFS caused by tumor compression on the facial nerve REZ, surgeons should try to find an offending vessel under the mass. This case supports the vascular compression theory as a pathogenesis of HFS.

We experienced one case of lateral orbitotomy(Berke's operation) in intraorbital tumor. We performed diagnostic studies for tumor location and vasculature in relation to eyeball and optic nerve, ie, orbital CT and orbital venogram. Tumor mass located in superior lateral region of orbit. Tumor mass was removed completely and successfully through 35 mm lateral skin incision.
