Objectives:
Despite precise iliosacral (IS) screw placement, we encountered a case of a neurological deficit due to a bony fragment that remained around the nerve root after reduction of the fracture gap in a patient with a pelvic ring injury.Summary of Literature Review: Percutaneous IS screw fixation is a commonly used procedure because it enables an adequate fixation force to be secured through a minimally invasive method in patients with pelvic ring fractures. Percutaneous IS screw fixation using C-arm fluoroscopy has been well described. In addition, several studies have investigated methods to prevent neurological damage.
Materials and Methods:
A 48-year-old man was diagnosed with a lateral compression type 1 pelvic ring fracture. Bilateral IS screw fixation was performed in the patient, who had no preoperative neurological abnormalities. He complained of pain around the sacroiliac joint that radiated to the lower leg after percutaneous IS screw fixation, and he was diagnosed with S1 radiculopathy on electromyography.
Results:
While reviewing the patient’s preoperative computed tomography images, a bony fragment in the fracture gap on the left S1 root was noted. After confirming S1 root entrapment, decompressive laminectomy was performed.
Conclusions
Surgeons should be aware that postoperative neurological symptoms may be caused by a bony fragment resulting from the fracture, regardless of screw malposition in percutaneous IS screw fixation. Preoperative planning with meticulous image review and intraoperative neurological monitoring, as well as using full-threaded screws, may help to prevent this problem.

PURPOSE: To evaluate the role of linac based radiosurgery (RS) in the treatment of meningiomas, we retrospectively analyzed the results of clinical and follow up CT/MRI studies. METHODS AND MATERIALS: From the 1988 July to 1998 April, twenty patients of meningioma had been treated with 6 MV linear accelerator based radiosurgery. Of the 20 patients, four (20%) were male and 16 (80%) were female. Mean age was 51 years old (22~78 years old). Majority of intracranial location of tumor for RS were parasagittal and sphenoid wing area. RS was done for primary treatment in 6 (30%), postoperative residual lesions in 11 (55%) and regrowth after surgery in 3 (15%). Mean tumor volume was 5.72 cm3 (0.78~15.1 cm3) and secondary collimator size was 2.04 cm (1~3 cm). The periphery of tumor margin was prescribed with the mean dose of 19.6 Gy (9~30 Gy) which was 40~90% of the tumor center dose. The follow up duration ranged from 2.5 to 109 months (median 53 months). Annual CT/MRI scan was checked. RESULTS: By the follow up imaging studies, the tumor volume was reduced in 5 cases (25%), arrested growth in 14 cases (70%), and increased size in 1 case (15%). Among these responsive and stable 19 patients by imaging studies, there showed loss of contrast enhancement after CT/MRI in four patients. In clinical response, nine (45%) patients were considered improved condition, 10 (50%) patients were stable and one (5%) was worsened to be operated. This partly resulted in necrosis after surgery. CONCLUSION: The overall control rate of meningiomas with linac based RS was 95% by both imaging follow-up and clinical evaluation. With this results, linac based RS is considered safe and effective treatment method for meningioma.

PURPOSE: To determine the morphology and location of normal pancreatic tail, as seen on abdominal CT. MATERIALS AND METHODS: A hundred and one patients without pancreatic disease underwent CT scanning. We thendetermined how to relate the location of the pancreatic tail with the splenic hilum, left kidney, and pancreaticbody. We compared the thickness of the tail with that of the body and analysed of the morphology of the tail. RESULTS: Seventy-seven percent of all pancreatic tails were located below the splenic hilum, with 59% of thisproportion located located 1 to 2 cm below. Fifty percent of tails were located at the level of the uppermostquarter of the left kidney, and a further 27% at the level of the second quarter ; 75% were located in theventrolateral portion of this kidney and 23% in the ventral portion. In 48% of patients, the pancreatic tail andbody were the same thickness, and in a further 48%, the tail was thicker than the body. In 34% of patients, thetail showed focal bulging, and in another 32%, it tapered smoothly. Forty seven percent of tails were locatedbelow the pancreatic body and a further 37% were found at the same level as the body. CONCLUSION: Abdominal CTscans showed differing morphology and location of the pancreatic tail. The recognition of these variations willdiminish speculation as to their true nature.

Malakoplakia is an uncommon granulomatous disease most frequently found in the bladder or ureter. Howevcr, it has been reyorted in almost every ather organ and structure, the colon is the most common site of malakoplakia outside the urogenital tract and colonic carcinoma is the most commonly associated disease. A case of malakoplakia of the colon in a 54-year-old female is reported. Sigmoidoscopy revealed multiple whiteyellowish nodules simulating polypoid lesion at 10cm from the anal verge. The biopsy showed characteristically comprised submucosal proliferations of histiocyte and chronic inflammatory cells with typical cytoplasmic inclusions known as Michaelis-Gutmann bodies. Intravenous pyelogram showed no evidence of involvement of the urinary system. These nodules were removed by endoscopic polypectomy, So far, this is the first case of isolated colonic malakoplakia in Korea.

We report a case of naturally-occurring anti-Miltenberger (anti-Mia(a)) antibody in a 16-year-old man who had never been transfused before. During an operation for a trauma he received 2 units of packed red blood cells. He was negative on an antibody screening test, but positive a week after the surgery when an extended screening test was conducted using blood cells positive for Miltenberger III (Mi.III) phenotype. The Mi.III phenotype is a low incidence antigen among Caucasians, however, it is reported to be relatively high in incidence among people in South-East Asia. Anti-Mia(a) antibodies are clinically significant antibodies that cause hemolytic transfusion reactions (HTRs) and hemolytic disease of the newborns (HDNs). In addition, anti-Mia(a) has a high rate of incidence among Thais, Taiwanese, and Hong Kong Chinese. There has been no particular report on Koreans regarding the incidence of this antibody, it would therefore require further research on the Mi.III phenotype and anti-Mia(a).
