PURPOSE: To evaluate the findings and the role of CT in plexiform neuro-fibromatosis of the mediastinum. MATERIALS AND METHODS: We retropectively reviewed the CT scans of five patients with plexiform neurofibromatosis of the mediastinum. The CT scans were reviewed with attention to the distribution of the lesions, appearance and attenuation of mediastinal lesions, enhancement pattern after intravenous contrast infusion and associated findingssuch as intercostal neurofibroma. RESULTS: In all five patients CT scans demonstrated fusiform low attenuated masses which were oriented longitudinally and extended over multiple contiguous scans along the distribution of major mediastinal nerves. In four patients, mediastinal lesions appeared infiltrative, obliterating adjacent mediastinal fat plane. One patient had well defined fusiform masses along the major mediastinal nerves. Postcontrast enhanced CT scans revealed slight central enhancement in two patient and no contrast enhancement in three patients. Associated findings such as neurofibromas of intercostal nerves and sympathetic trunk, or subcutaneous neurofibromas were detected on CTscans in all five patients. CONCLUSION: Characteristic CT findings of low attenuation masses along the major mediastinal nerves are helpful to differentiate plexiform neurofibromatosis from mediastinal lymphadenopathy and to prevent from misreading as a malignant disease.

The present study was performed to compare maternal and perinatal outcomes in triplet and twin pregnancies with the result of ART(Assisted Reproductive Technology). Each pregnancy of 18 triplet pregnancies with 18 weeks or more was matched for maternal age, EDC(estimated date of confinement), parity, history of preterm delivery, indication of ART with two sets of twin pregnancies. Triplet pregnancies had a significantly shorter gestational age at delivery than twin pregnancies(30.4 versus 34.6 weeks), and a significantly lower mean birth weight(1,514 versus 2,286g). The mean hospital stay was significantly longer in triplets(22.3 versus 10.1 days). The incidences of 5 min Apgar score less than 7, neonatal deaths were significantly more often in triplets than twins; 18(33.3%) vs 6(8.3%), 15(27.8%) vs 7(9.72%), respectively. There were significant differences in the incidence of neonatal complications such as respiratory distress syndrome; 14(25.9%) vs 7(9.72%), ventilatory support; 18(33.3%) vs 5(6.9%), neonatal seizure; 9(16.7%) vs 0, btween the two groups. However, there were no significant differences between the groups in maternal complications or neonatal morbidity such as congenital malformations or hyperbilirubinemia, intraventricular hemorrhage, or bronchopulmonary dysplasia. We suggest that counseling patient regarding the anticipated perinatal outcomes of triplet pregnancies with the result of ART should be conducted with our data.

PURPOSE: We evaluated clinical characteristics, sperm retrieval rates, and birth rates in a relatively large number of infertile patients with Y chromosome microdeletions. MATERIALS AND METHODS: We retrospectively reviewed clinical data from 213 patients with nonobstructive azoospermia (NOA) and 76 patients with oligoasthenoteratozoospermia (OATS) who were tested for Y chromosome microdeletion from March 2004 to June 2011. RESULTS: Of the 289 patients, 110 patients presented with Y chromosome microdeletion and 179 patients presented with no microdeletion. Among the patients with Y chromosome microdeletions, 83/110 (75.4%) were NOA patients and 27/110 (24.5%) were OATS patients. After subdividing the patients with Y chromosome microdeletion, 29 had azoospermia factor (AZF)b-c microdeletion and 81 had AZFc microdeletion. The sperm retrieval rate was similar between patients with Y chromosome microdeletion and those with no microdeletion (26.6% vs. 25.6%, p=0.298) after multiple testicular sperm extraction (TESE). Excluding 53 patients who did not undergo TESE, 30 patients were analyzed. All of the 9 men with AZFb-c microdeletion had a complete absence of sperm despite multiple TESE. However, multiple TESE was successful for 9 of 21 patients with only AZFc microdeletion (p=0.041). Twenty patients with Y chromosome microdeletion gave birth. CONCLUSIONS: In NOA and OATS patients, no significant difference in the sperm retrieval rate was shown between patients with Y chromosome microdeletion and those with no microdeletion. Patients with short Y chromosome microdeletion such as AZFc microdeletion have better prognoses for sperm retrieval and an increased chance of conception than do patients with larger microdeletions such as AZFb-c microdeletion.

Purpose: To compare perioperative outcomes according to surgical methods among bladder cancer patients who underwent radical cystectomy (RC) with neobladder urinary diversion. Materials and Methods: Between June 2007 and January 2020, 89 bladder cancer patients who received RC with neobladder urinary diversion were enrolled in this study. Patients were stratified into surgical methods – (1) open RC with neobladder (ONB) reconstruction, (2) robotassisted RC (RARC) with extracorporeal neobladder (ECNB) reconstruction, and (3) RARC with intracorporeal neobladder (ICNB) reconstruction. Perioperative outcomes were compared among the 3 groups, with major complications defined according to Clavien-Dindo grades III–V within 90 days. Logistic regression analysis was performed to identify significant factors for postoperative complications. Results: Of 89 patients, 28 (31%) had ONB, 31 (35%) had ECNB, and 30 (34%) had ICNB. The median operative time was 471 minutes, and the ICNB group (424.5 minutes) was significantly less than ONB (444.5 minutes) and ECNB groups (542.9 minutes) (p=0.001). Transfusion rate was also significantly less in the ICNB group (13%) (p=0.001). Complications were recorded in 67 patients (75%) and major complications in 22 of all patients (25%). The major complication rate was significantly less in ICNB (13.4%) than in ONB (25%) and ECNB (35%) (p=0.003). Multivariate analysis showed surgical methods (ICNB) (odds ratio [OR], 0.709; p=0.003) and age (OR, 1.150; p=0.001) were significant factors related to occurrence of major postoperative complications. Conclusions RARC with ICNB reduces postoperative complications compared to ONB and ECNB.

Paragonimiasis has been continuously decreasing in Korea. However, it still occurs by ingesting raw or incompletely cooked fresh water crab or crayfish. The diagnosis of paragonimiasis is challenging because of its rarity. It may be confused with other inflammatory disease or carcinomatosis. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has lower risk of complications such as bleeding, perforation than percutaneous fine needle aspiration. EUS-FNA is more accurate and popular method to find mucosal or submucosal tumors and the lesions of several organs. Benign and malignant tumors, infectious diseases have been diagnosed by EUS-FNA, but there was no report describing the use of EUS-FNA for diagnosing paragonimiasis. Herein, we present a 47-year-old male patient with paragonimiasis diagnosed by EUS-FNA. Imaging studies revealed mass lesions in the lung and peritoneal cavity, which was eventually confirmed as paragonimiasis using EUS-FNA.

PURPOSE: To evaluate the prevalence of vesicoureteral reflux (VUR) according to the timing of voiding cystourethrography (VCUG) in infantile urinary tract infection (UTI). METHODS: The data of 134 infants (1-12 months) with renal cortical defect in 99mTc-2, 3-dimercaptosuccinic acid (99mTc-DMSA) scan with a diagnosis of UTI in two hospitals from 2000 to 2010 were retrospectively analyzed. The VCUG was performed after 2 weeks from the diagnosis of UTI in Group I (n=68), and the VCUG was performed within 2 weeks from the diagnosis of UTI in Group II (n=66). RESULTS: There were no significant differences between the two groups in the duration of fever, white blood cell count, C-reactive protein levels, and abnormalities in ultrasonography (P>0.05). There was no significant difference between the two groups in the prevelence of VUR, bilateral VUR, and severe VUR. VCUG-induced UTI was detected 16 (23.5%) of patients in whom the procedure was performed 2 weeks after the diagnosis, and none of VCUG-induced UTI occurred in those in whom the procedure was performed 2 weeks within the diagnosis. CONCLUSION: We conclude that the prevalence of VUR according to the timing of VCUG did not differ between the two groups in infantile UTI with renal cortical defect in DMSA scan. We also found that performing VCUG with antibiotics can decrease risk of VCUG-induced UTI.

Post-lumbar puncture headache (PLPH) is a common complication developed after lumbar puncture, and it usually begins within 48 hours. The pain is postural; the it is relieved by reclining and worsened by sitting. Moreover, there are some related symptoms such as nausea, vomiting, tinnitus and blurred vision. PLPH is rare in children and it is effectively treated by bed rest and conservative treatment. However, when the pain is too severe or continuous or different types of headache are seen after LP, it is worthwhile to conduct brain MRI for exact diagnosis and proper treatment. Therefore, we report a patient with PLPH in whom brain MRI showed diffuse meningeal enhancement and concurrent cerebral venous expansion, with a review of literatures.

OBJECTIVE: Chronic subdural hematoma (CSDH) is known to have a significant recurrence rate. There are different criteria defining the recurrence of CSDH. We evaluated the postoperative course of CSDH and tried to propose the reasonable criteria of recurrence. METHODS: We retrospectively examined the medical records and pre- and postoperative CT scans of 149 consecutive patients who underwent surgery from January 2005 to December 2009. Diagnosis was confirmed by CT scanning or MRI. The postoperative courses were either resolved or recurrent. The resolved CSDH was one of the three types; early resolution, delayed resolution, or late resolution. The recurrent CSDH was one of the four types; recurrence without resolution, early recurrence after resolution, late recurrence after resolution, or recurrent-and-resolved type. RESULTS: The CSDH was resolved within 30 days after surgery in 58 (39%) patients, between 1 to 3 months in 62 (42%), and after 3 months in 11 (7%) patients. The CSDH was recurred in 18 (12%) patients. Late resolution or recurrence was more common in the aged. The recurrent hematoma was seen on the same side in 11 patients, on the different side in 7 patients. Recurrence was significantly more common in the thick hematomas. CONCLUSION: For a working criteria of the recurrence of CSDH, we propose the early recurrence as return of symptoms or reaccumulation of the hematoma after a surgery within 3 months regardless of the location, amount or repeated operations. The late recurrence can be defined as reappearance or enlargement of a liquefied hematoma within the cranial cavity surrounded by the membranes or persistent CSDH beyond 3 months after surgery.

The familial occurrence of intracranial aneurysms, defined as the presence of one or more aneurysms in two or more blood relatives, is well established and is relatively rare. The pattern of inheritance in these families is not usually known. The authors report one case of familial intracranial aneurysm, without specific genetic disorder, occurring during a recent six-month period in three of five siblings. Two of these were females, aged 36 and 39, and the other was a 40-year-old male. Two of these patients had ruptured aneurysms, but in the other, the aneurysm was unruptured. All were treated successfully by clipping of the aneurysmal neck, without any neurological deficits. The authors describe their experience of a rare familial intracranial aneurysm, occurring in the absence of a specific genetic disorder, and review the literature concerning this type of aneurysm.
