OBJECTIVE: To describe normal postoperative MR findings and MR findings of postoperative discitis in patients who underwent operation due to herniated intervertebral disc. MATERIALS AND METHODS: We retrospectively reviewed normal postoperative MR findings and MR findings of discitis in 30 patients(21-61yrs.) (13 cases dignosed as discitis and 17 cases as normal) who previonsly underwent laminectomy and discectomy, or bony fusion. We analyzed signal intensity of end plate and disc, end plate destruction, and enhancement of end plate and disc on T1- and T2-weighted images(WI) of 1.5T MRI. RESULTS: Among 14 out of 17 patients with no evidence of discitis, 7 patients showed high signal of the posterior portion of disc on T1- and T2-WI and 11 patients revealed enhancement at the same sites. In all 13 patients suspected of having discitis, end plate and disc showed low signal on T1-WI, high signal on T2-WI, heterogeneous enhancement, and irregular destruction of end plate. Meanwhile, 3 cases with no evidence of postoperative discitis clinically who underwent bony fusion showed similiar findings to those of the above 13 patients, except for homogeneous enhancement of end plate and vertebral body. CONCLUSION: The MR findings of postoperative discitis were low signal on T1-WI, high signal on T2-WI, and heterogeneous enhancement of and plate and disc, and destruction of end plate.

PURPOSE: The purpose of this study was to evaluate the spectrum of MR characteristics of cystic acoustic neurinomas and to correlate with pathologic findings. MATERIALS AND METHODS: We retrospectively reviewed the MR findings of 12 patients with cystic acoustic neurinomas. The signal intensity and enhancement pattern of the cystic components as well as the location relative to the tumors were analyzed. RESULTS: A total of 30 cysts were found in 15 acoustic neurinomas;28 were intratumoral cysts and the remaining two were extratumoral cysts. The signal intensity of all 28 intratumoral cysts was higher than that of CSF on Tl-weighted images, and isointense to CSF on T2-weighted images, while the signal intensity of the two extratumoral cysts was same as CSF on both Tl-weighted and T2-weighted images. Rim enhancement was seen in 27 of 28 intratumoral cysts but in none of the two extratumoral cysts. CONCLUSION: We concluded that intratumoral cyst was due to tumoral necrosis, hemorrhage or degenerative change and extratumoral cyst due to secondary arachnoid cyst formation.

The purpose of this study was the long-term clinical and radiological evaluation of conservatively treated condylar fractures in children. This study was therefore undertaken to analyze the long-term effects of treating condylar fractures in children with conservative therapy in order to resolve the controversial question of whether complete remodeling occurs in this age or, if not, whether it is more likely to be associated with certain types of fracture or with other factors. This study was based on a series of 11 consecutive children and adolescents, aged between 3 and 15 years, with fractures of the condylar process who had been treated with conservative therapy at the Department of Oral and Maxillofacial surgery, Inha University Hospital, Inchon, Korea. All patients underwent a clinical investigation with special emphasis on Temporomandibular joint function and facial asymmetry. The patients also underwent a radiologic investigation, focusing on fracture remodeling and symmetry of mandible. It consists of panoramic radiograph, PA and lateral cephalogram and 3-D CT. No patient described impaired temporomandibular joint(TMJ) function or pain on the affected side. 2 of 8 (25%) unilateral and 1 bilateral fractures show slight facial asymmetry. Despite apparently excellent recovery of function, there were marked remodeling changes evident on the CT scan. Such changes are not usually evident on panoramic radiograph. Radiologic investigation showed incomplete remodelling(54.5%) and asymmetry of the mandible (27.3%) in some patients. Conservative treatment of condyle fracture in children results in satisfactory long-term outcome of jaw function despite a relative high frequency of radiologically noted aberrations.

A-59-year old man was admitted to the hospital with a 2-month history of the right pleuritic chest discomfort and mild dyspnea. Seven years earlier, he was operated on left pneumonectomy for squamous cell carcinoma of left upper lobe (Stage IIb, T2N1M0). The computed tomographic scan revealed an anterior herniation of the right lung in the left hemithorax. A single thorax after receiving pneumonectomy is called a "buffalo chest" because the absence of an anatomical separation of the two hemithoraxes resembles that of the North American buffalo or bison. A possible pneumothorax should be catastrophic for the patient, so he should be closely monitored regarding any invasive procedure or trauma. He improved after symptomatic treatment.

Synovial fistula of the ankle joint is an uncommon complication from an ankle sprain. This may likely result in an unhealed wound around the ankle joint due to continuous leakage of joint fluid. However, in the event of an open wound on the lower leg, and not on the joint, it may be difficult to consider synovial fistula as a cause of the open wound. We experienced an interesting case with an unhealed open wound on the lower leg due to a synovial fistula of the ankle joint following an ankle sprain. We obtained good results after a treatment using a self-produced suction drainage device on the unhealed open wound.

PURPOSE: This study was conducted to perform a comparative analysis of the efficacy and safety of conventional transurethral resection of the prostate (TUR-P), transurethral resection in saline (TURIS), and TURIS-plasma vaporization (TURIS-V) when performed by a single surgeon for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: The clinical data of 73 consecutive men who underwent conventional TUR-P (39), TURIS (19), or TURIS-V (15) for BPH were retrospectively analyzed. All procedures were carried out by a single surgeon between October 2007 and April 2010. The patients were assessed preoperatively and perioperatively and were followed at 1, 3, and 6 months postoperatively. Patient baseline characteristics, perioperative data, and postoperative outcomes were compared, and major complications were recorded. RESULTS: In all groups, significant improvements in subjective and objective voiding parameters were achieved and were sustained throughout follow-up. TURIS-V had the shortest operation time compared with conventional TUR-P and TURIS (p=0.211). TURIS-V significantly decreased procedural irrigation fluid volume, postoperative irrigation duration, catheter duration, and hospital stay compared with conventional TUR-P and TURIS. There were no significant differences between the groups in hemoglobin levels or serum sodium levels before and after the operations. There were three transfusions and four clot retentions in the TUR-P group, and one transfusion and one clot retention in the TURIS group. The TURIS-V group had no complications. CONCLUSIONS: TURIS and TURIS-V were effective for the surgical treatment of BPH in addition to conventional TUR-P. TURIS-V was not inferior to conventional TUR-P or TURIS in terms of safety.

A weanling Thoroughbred foal was admitted to Equine Hospital, Korea Racing Association with signs of colic. On admission the foal was sweating profusely, appeared anxious and exhibiting signs suggestive of abdominal pain. Clinical examination revealed: tachycardia (90 beats/min), tachypnea (50 breaths/min) and congested and slightly cyanotic mucous membranes. No intestinal sounds were auscultated in all 4 abdominal quadrants. Rectal palpation identified concurrent cecum and large colon impactions. Treatment consisted of intravenous administration of a balanced electrolyte solution, nasogastric siphonage and administration of analgesics. Nasogastric reflux contained ascarids. This treatment failed to alleviate the signs of colic. The foal died 3 hours later following discharge because the owner didn't want laparatomy because of economic constraints. Prior to admission this foal had not received any prophylactic anthelmintic treatment. In necropsy, there were masses of ascarids accumulation in the stomach, small intestine and large intestine. The outcome of this report is to describe the first diagnosed case of gastrointestinal impaction by P. equorum in a Thoroughbred foal in South Korea and indicates the importance of regular anthelmintic treatment.
