Male urethral diverticulum is uncommon lesion, furthermore calculus formation within the male urethral diverticulum is very rare. Generally, urethral diverticula are classified as congenital and acquired. The majority of male urethral diverticula are acquired and approximately 10 to 20 per cent are congenital. Acquired urethral diverticula in the male may arise from many sources, including infection (prostatic abscess, infection of periurethral glands, hematoma or schistosomiasis), obstruction (stricture, impacted stone, Cunningham clamp or condom catheter) and trauma (instrumentation, external injury and pelvic fracture). Calculi formation is more common in the acquired diverticulum owing to stagnation of urine and infection. These calculi in the diverticulum usually are solitary and may attain considerable size with predisposing factors, 1) a ureteral or bladder calculus that is lodged in the urethra 2) urethral trauma or stricture, 3) calcification around a foreign body or hair. The treatment of urethral diverticulum combined with stone is excision of the diverticula with removal of stone. We treated two cases of urethral diverticulum combined with stone in the male, and report with review of literature.

PURPOSE: To determine the mean liver CT numbers, and differences between liver and spleen, and liver and back muscle CT numbers in normal children, and to correlate the findings with sex and age. MATERIALS AND METHODS: One hundred and five normal children aged 2-14 years underwent pre-contrast CT scanning. Mean CT numbers of the liver, spleen, and back muscles were calculated, as well as the differences in CT numbers between the liver and spleen (liver-spleen CT numbers), and between the liver and back muscles (liver-back muscles CT numbers). The results were correlated with age and sex. RESULTS: For all children, mean liver, spleen, and back muscle, and liver-spleen and liver-back muscle CT numbers were 70.22+/-6.51 HU, 53.28+/-3.0 HU, 58.31+/-3.57 HU, 17.13+/-6.57 HU, and 11.88+/-5.94 HU, respectively. Mean liver CT numbers and the difference between liver and spleen CT numbers were high in children aged less than seven, bet mean spleen and back CT numbers, and the difference between liver and back muscle CT numbers were not different by age. By sex, all the CT numbers did not vary according to age. The sex of a subject did not affect the CT number. CONCLUSION: The children's mean liver CT number was 70.22+/-6.51 HU and the difference between liver and spleen CT numbers was 17.13+/-6.57 HU. Younger children had higher liver CT and liver-spleen CT numbers than older children. No CT numbers varied according to sex.

Eosinophilic esophagitis is a rare inflammatory disease of unknown origin. Its reported CT findings are circumferential wall thickening of the entire esophagus, with pleural effusion and ascites.

Objective To investigate the vowel's nasalance and contact quotient (CQ) in children with hearing loss. Methods 57 subjects were divided to 3 groups: profound hearing loss children with hearing aids (HA, n=19), profound hearing loss children with cochlear implant (CI, n=19) and children without hearing loss (n=19). With the help of NV and electroglottography (EGG), the subjects' nasalance and CQ were recorded when they said /a/, /æ/, /i/, /o/, /u/. Results There was no significant differences among the 3 groups on nasalance (P>0.05). There was significant difference among 5 vowels on nasalance, ranked as /u/, /o/, /æ/, /i/, and /a/ (P<0.001). There was significant difference among 3 groups on CQ, ranked as HA, normal, and CI group (P<0.001). There was significant difference on CQ among 5 vowels,ranked as /i/, /u/, /æ/, /o/, and /a/ (P<0.001). Conclusion The voice and resonance should be assessed before speech therapy, which the speech therapy starts from the most correct vowel for children with profound hearing loss.

We report thin-section CT findings of pulmonary fat embolism which was confirmed by clinical features and microscopic examination of cells obtained by bronchoalveolar lavage. Initial thin-section CT showed extensive air space consolidation and multiple ill-defined nodular densities in both lungs. Follow-up CT revealed ground-glass appearance and faint nodules in both lungs. Perfusion scan showed multiple small perfusion defects in the peripheral portion of both lungs.

PURPOSE: To determine the long-term follow-up CT findings of paraquat-induced lung injury. MATERIALS AND METHODS: Six patients who ingested paraquat underwent sequential follow-up CT scanning during a period of at least six months, and the results were analysed. Scans were obtained 1-6 (mean, 3.3) time during a 7-84 (mean, 25.7) months period, and the findings at 1-2 months, 3-12 months, 1-2 years, 2-3 years, and more than above 7 years after poisoning were analyzed. RESULTS: We observed irregular-shaped areas of consolidation with traction bronchiectasis at 1-2 months (5/5), irregular-shaped consolidation and ground-glass opacity (5/5) at 3-12 months, and irregular-shaped consolidations/ ground-glass opacity (4/5) and focal honeycombing (1/5) one year later. In the same patients, follow-up CT scans showed that some areas of focal consolidation could not be visualized and the radio-opacity of the lesions had decreased. CONCLUSION: The HRCT findings of paraquat-induced lung injury were irregular shaped areas of consolidation 1-2 months after ingestion, and irregular-shaped consolidation and ground-glass opacity or focal honeycombing 3-12 months later. At this thim slight improvement was observed.

Trauma is the third leading cause of death, irrespective of age, and the leading cause of death in personsunder 40 years of age. Most pleural, pulmonary, mediastinal, and diaphragmatic injuries are not seen onconventional chest radiographs, or are underestimated. In patients with chest trauma, CT scanning is an effectiveand sensitive method of detecting thoracic injuries and provides accurate information regarding their pattern andextent.

We illustrate serial HRCT findings over a 16-month period in a 35-year-old woman who had ingested paraquat. Initial areas of ground-glass opacity changed into areas of multiple air cysts on follow up scan obtained five months after ingestion. A further follow-up scan obtained 16 months after ingestion showed improvement, with increased lung volume and normalized lung architecture.

PURPOSE: The purpose of this study is to analyze and compare the CT findings of gastric adenocarcmoma and gastric lymphoma. MATERIALS AND METHODS: We retrospectively analyzed and compared the CT findings in 46 cases of adenocarcinoma and 12 cases of lymphoma, which were pathologically confirmed by operation and endoscopic biopsy. RESULTS: Antral involvement was more common in adenocarcinoma(71.7%) than in lymphoma(41.7%). Localized involvement was more common in adenocarcinoma(83.7%), while diffuse involvement was more common in lymphoma(55.6%). Adenocarcinoma tended to have smooth inner margin(83.8%), while lymphoma had nodular or irregular inner margin(36.4%). Mean gastric wall thickness of adenocarcinoma was 1.7cm, while mean thickeness of lymphoma was 2.7cm. The involved wall of adenocarcinoma tended to be highly enhanced (59.5%), while lymphoma was moderately enhanced(90.1%). Perigastric lymphadenopathy was present in 40% (group I) and 42%(group II) of adenocarcinoma and 33% of lymphoma(group I and II). Three cases of lymphoma had lymphadenopathy below renal vascular pedicles with no or minimal perigastric lymphadenopathy. When only the distal portion of the stomach was involved, disturbance in passage developed in six adenocarcinoma (12%), while none developed in the lymphoma. CONCLUSION: CT features help to differentiate between gastric adenocarcinoma and gastric lymphoma
