Objective To improve the knowledge of radiological manifestations , pathologic basis and differential diagnosis of hemangioma of long bones in children.Methods 7 cases with hemangioma of long bones proved by surgery and pathology were retrospectively analyzed .Results The X-ray features mainly included : (1) "soap bubbles" or cystic appearance;(2) "mesh" sign or "honeycomb" appearane,with or without cystic bone destruction;(3) Localized cortical thickening.Conclusion Radiographic findings of hemangioma of long bone is varied and relevant to pathological type, growth speed and pattern of tumor ; Though these will provide some help in diagnosis but it should be based on pathological evidence .

Objective To explore the efficacy and safety of minimal invasive adrenal sparing surgery for the treatment of Cushing syndrome caused by adrenocortical adenoma.Methods Patients who underwent minimal invasive adrenal surgery for adrenocortical adenoma in our institution from January 2010 to December 2015 were retrospectively analyzed.Preoperative, intraoperative, and postoperative variables were reviewed from the database.The mean patient age at diagnosis was 39 years and male:female ratio was 10:111.Of the 121 adenomas, 50 were located in the right adrenal and 71 in the left.The mean tumor size was 2.6 cm.84 cases had hypertension (69.4%), 36 cases had diabetes mellitus (29.8%), and 45 cases had obesity (37.2%).Postoperative follow-up was performed by evaluating adrenal gland function and imaging.Results Mininal invasive partial adrenalectomy was performed in 121 cases and the success rate of operation was 99.2% (120/121).Sixty-two cases received operation through retroperitoneal approach,and 59 cases were through transperitoneal approach.The median operative time was 50 min with a median blood loss of 50 ml.The mean postoperative hospital stay were (5.0 ± 3.2) days.The vascular injury occurred in 2 cases (1 case in each surgical approach), while the abdominal organ injury occurred in 2 cases with 1 case of spleen injury and 1 case of liver injury (both in transperitoneal approach).Postoperative complications were observed in 6 cases:1 case of deep venous thrombosis, 1 case of wound hematoma, 4 cases of wound infection.Cortisol substitution was given in 2 to 12 months (mean 6.2 months)postoperatively.One year after operation, the remission rate of hypertension, diabetes and obesity was 58.3% (49/84), 30.6% (11/36) and 60.0% (30/45), respectively.Conclusions Minimal invasive adrenal surgery using retroperitoneal and transperitoneal laparoscopic technique can be performed with low morbidity and achieve an excellent outcome.The perioperative hormone therapy may also play an important role.

Objective To discuss the clinical characteristics of adrenal metastases,and summarize the experience of diagnosis and treatment.Methods From January 2008 to June 2018,the clinical data of 55 patients with adrenal metastases treated in our hospital were analyzed retrospectively.This study included 34 male patients and 21 female patients and the median age was 60 years old (ranged 55 to 84 years old).The median value of maximum diameter of adrenal metastases was 3 cm (ranged 1.9 to 10.3 cm);with 35 cases on the left side,13 cases right and 7 cases bilateral.The primary sites of malignant tumors were pancreas (18 cases,32.7%),lung (12 cases,21.8%),liver (6 cases,10.9%) and colorectum (6 cases,10.9%),respectively.Thirty-four cases were confirmed by pathology after adrenalectomy and 21 cases were confirmed by needle biopsy.Thirty cases were diagnosed synchronously with the primary tumor and 25 cases were metachronous.The median time from diagnosis of primary tumors was 13.3 months (ranged 2.0 to 97.4 months).42 cases of these 55 cases were diagnosed within one year.Treatment options for adrenal metastatic lesions included single adrenalectomy in 18 cases,adrenalectomy combined with radiotherapy 16 cases,single intravenous chemotherapy 10 cases,intravenous chemotherapy combined with non-operative treatment 10 cases and single radiotherapy 1 case.Results The main pathological types were adenocarcinoma (19 cases,34.5%),ductal adenocarcinoma (10 cases,18.2%),hepatocellular carcinoma (6 cases,10.9%) and clear cell carcinoma (4 cases,7.3%).Two cases were lost follow-up and the follow-up rate was 96%,the median follow-up time was 8 months (ranged 1 to 135 months).The median overall survival (OS) time of 55 patients was 5.3 months (ranged 1 to 134 months).The one-year survival rate was 23.6% (13/55),the two-year survival rate was 12.7% (7/55),the three-year survival rate was 9.1% (5/55) and the five-year survival rate was 1.8% (1/55).Conclusions Pancreatic cancer was the most common type of malignant tumor for adrenal metastases in our hospital.Most primary tumors and adrenal metastases were diagnosed synchronously or within one year.Comprehensive treatment with retroperitoneal adrenalectomy may improve the OS,however the overall prognosis is poor.

[Abstract] Objective To explore the relationship between supratentorial area (STA), posterior fossa area (PFA) and intracranial area (ICA) of normal adult Tibetans with age and gender. Methods The subjects of this study were native Tibetan adults living in Lhasa. Totally 158 sample populations were between the ages of 20 and 59 years, with an average age (36. 60 ± 10. 75) years, including 64 males and 94 females. Siemens MAGNETOM ESSENZA 1. 5T magnetic resonance scanner was used to scan with 3D-fSPGR sequence, and the images obtained by scanning were stored in DICOM format and imported into 3D Medical medical image processing software, and region of interest was delineated by using the software’s own toolkit. STA, PFA and ICA were measured on T1WI mid-sagittal imaging, and the ratios of PFA / STA, STA / ICA and PFA / ICA were calculated. In order to eliminate the influence of individual differences in skull size on brain structure, this paper corrected the STA and PFA with the same level of ICA, and obtained the relativity of supratentorial area (RSTA) and relativity of posterior fossa area (RPFA). Results The STA was (127. 91 ± 9. 84) cm
