Inflammatory myofibroblastic tumor (IMT) occurring in the pancreas was rare and few clinical cases had been reported. The specificity of clinical presentation of IMT was lacked and its CT imaging manifestations were diverse. The enhanced CT images of a rare patient with IMT of the pancreas with liver metastases were presented to the readers, and the pathophysiological mechanisms associated with the CT imaging manifestations were briefly described, so as to enhance the readers’ understanding and knowledge of the CT imaging manifestations and raise the diagnostic awareness of the disease.
Schwannoma originating from the common bile duct is rare. We presented a patient who was diagnosed with biliary cystadenoma preoperatively and pathologically confirmed as a choledochal Schwannoma, analyzed the CT and MRI imaging manifestations, and illustrated its anatomical and pathological basis, and to improve the understanding of clinicians and radiologists for choledochal Schwannoma.
Methods of evidence-based medicine were used to discuss the drug treatment of postmenopausal osteoporosis. After clinical problems were put forward, we searched for and assessed the evidence. A rational treatment plan for osteoporosis patients with fractures was developed according to the results of systematic reviews and Meta-analysis.
Objective To summarize the pathological, clinical features and research progress of CT diagnosis of signet ring cell carcinoma of the stomach, in order to help further understanding and early clinical diagnosis and treatment of this disease. Method The literatures related to pathological classification, clinical manifestations, metastasis patterns, prognosis and CT features of gastric signet ring cell carcinoma were searched and reviewed. Results Gastric signet ring cell carcinoma often had no special clinical symptoms and signs in the early stage, and often entered the advanced stage when symptoms such as gastric ulcer appeared. Gastric signet ring cell carcinoma is more prone to peritoneal and ascites metastases than other types of gastric cancer. The more specific metastases include diffuse infiltration along the bile duct and portal vein to the hepatic hilar area and extension to the Glisson sheath. Compared with other types of gastric cancer, there is no prognostic advantage. even worse. CT showed that the lesions were mostly located in the middle and lower 1/3 of the stomach, with a diffuse infiltrating gross appearance, obvious thickening and enhancement of the gastric wall, and delayed enhancement, especially in the low-enhanced area. The emerging dual-energy/spectral CT has shown good application prospects for the diagnosis of gastric cancer. Conclusions The pathological clinical features and CT diagnosis of gastric signet ring cell carcinoma have certain characteristics, but there are still many controversies, which are related to the fact that some pathological characteristics or infiltration patterns of gastric signet ring cell carcinoma itself have not been clearly studied, which will be discussed in the future direction of continuing research.
ObjectiveTo summarize the mechanism, risk factors, clinical manifestations, and medical treatment of hungry bone syndrome (HBS) in patients with hyperparathyroidism after parathyroidectomy, and to provide clinicians with reference for disease diagnosis and treatment.MethodThe related literatures about HBS in patients were collected and reviewed with clinical experience.ResultsHBS was a group of clinical syndromes mainly manifested as hypocalcemia after parathyroidectomy in patients with high bone turnover state before operation, with a high incidence, and the main purpose of treatment was achieved by supplementing calcium and vitamin D.ConclusionsHBS requires reasonable diagnosis and timely treatment by clinicians. Patients can achieve long-term blood calcium and phosphorus stability and bone mass growth through medical treatment.
Inflammatory myofibroblastic tumor (IMT) involving stomach, liver, biliary tract, and peritoneal mesentery was very rare, nonspecific clinical manifestations and laboratory examination were the main reasons for the difficult preoperative diagnosis of IMT. An IMT case involving multiple systems and multiple sites of the abdomen was presented, the CT and MRI imaging signs and pathological basis of IMT were illustrated, so as to strengthen the understanding of IMT for clinicians and radiologists.
目的 探讨经皮椎体成形术（percutaneous vertebroplasty，PVP）后新发椎体骨折的发生率及危险因素。 方法 回顾分析2004年1月-2009年1月行经PVP治疗的80例骨质疏松伴椎体压缩骨折的患者的临床资料，随访7～54个月，了解患者的疗效和预后。 结果 术后80例中14例（17.5%）30个椎体新发椎体骨折，其中相邻椎体占46.7%（14/30）。有无新发椎体骨折两组间及相邻和非相邻椎体骨折两组间，体重指数（body mass index，BMI）比较差异均统计学意义（Plt;0.05），而年龄、性别、骨折椎体个数、PVP手术椎体个数、骨水泥注射剂量、身高下降比较差异无统计学意义（Pgt;0.05）。经logistic回归分析发现低体重指数（BMI≤18.5 kg/m2）是PVP术后新发椎体骨折的独立危险因素。术后患者均给予抗骨质疏松药物治疗，58.8%（47/80）的患者能坚持抗骨质疏松药物治疗1年以上。采用KaplanMeier法计算术后第1年新发椎体压缩骨折的发生率为8.6%。低新发椎体骨折发生率与患者术后坚持抗骨质疏松治疗相关。 结论 低体重指数是PVP术后新发椎体骨折的独立危险因素，与PVP手术本身无关。术后坚持抗骨质疏松药物治疗能够降低新发椎体骨折的发生。
Hepatic sinusoidal obstruction syndrome (HSOS) can be easily missed or misdiagnosed as Budd-Chiari syndrome in clinical practice. The authors displayed the imaging pictures of one patient with HSOS and made a brief description of typical imaging features, underlying pathophysiological mechanisms, and differential diagnosis of HSOS, with the hope of improving the understanding of HSOS and reducing the rates of leak diagnosis or misdiagnosis.
Lymphoma originating in the liver is rare and few clinical cases had been reported. The imaging manifestations of primary hepatic lymphoma (PHL) were lack of specificity and diverse. The authors displayed the CT and MRI images of one patient with diffuse infiltrating PHL and made a brief description of imaging features, underlying pathophysiological mechanisms, and differential diagnoses of PHL, with the hope of strengthening the understanding of PHL for clinicians and radiologists.
