    一种罕见的局部侵袭性血管肿瘤,青少年鼻咽血管纤维瘤(JNA)主要影响男性青少年。本文描述了一名14岁的男性患者,他表现为嗜睡和复发性鼻出血,这是JNA的症状。CT和MRI扫描证实血管肿块具有明显的局部侵袭,起源于蝶腭孔。CT血管造影后,这揭示了肿瘤的大量血液供应,并有助于有效切除,设计了一个有针对性的手术策略。组织病理学证实了肿瘤的良性性质,手术成功,患者顺利康复。这个案例增加了关于JNA的小文献。它强调了医疗保健专业人员在管理疾病时需要了解早期识别和仔细的术前准备的要求。
    A rare and locally aggressive vascular tumor, juvenile nasopharyngeal angiofibroma (JNA) mostly affects male teenagers. This paper describes a 14-year-old male patient who presented with lethargy and recurrent nasal bleeding, which are symptoms of JNA. CT and MRI scans confirmed a vascular mass with a significant local invasion originating from the sphenopalatine foramen. After a CT angiography, which revealed the tumor\'s large blood supply and helped with efficient excision, a focused surgical strategy was designed. Histopathology verified the benign nature of the tumor, and the operation was successful and the patient had a smooth recovery. This case adds to the little literature on JNA. It highlights the need for healthcare professionals to be aware of the requirement of early identification and careful presurgical preparation in managing the illness.

    目的该研究的目的是使用国家儿科住院数据库评估术前血管栓塞(PVE)对青少年鼻咽血管纤维瘤(JNA)手术结果的影响。方法查询1997年至2016年JNA所有手术管理病例的医疗费用和利用项目儿童住院患者数据库。根据患者是否接受PVE对病例进行分层。在控制患者人口统计学因素和合并症的同时,使用多元线性回归预测PVE对住院时间(LOS)和总费用的影响。使用二元逻辑回归计算PVE患者接受围手术期输血的比值比(OR)。结果共有473例患者在此时间段内接受了JNA手术切除。PVE的使用率从1997年的0%增加到2016年的66%。发现PVE可将LOS降低1天(p=0.036),并降低需要围手术期输血的几率(OR=0.511,p=0.041)。接受PVE的患者被额外收取35,600美元(p<0.001),但2016年的最新数据表明,PVE的医院成本正在下降。结论JNA的PVE越来越普遍。栓塞导致医院LOS降低和需要输血的几率降低。虽然栓塞增加了管理成本,这一趋势应该重新评估,因为这一程序正变得越来越普遍。
    Objectives  The aim of the study is to evaluate the effect of preoperative vascular embolization (PVE) on juvenile nasopharyngeal angiofibroma (JNA) surgical outcomes using a national pediatric hospitalization database. Methods  The health care cost and utilization project Kids\' Inpatient Database was queried for all cases of operative management of JNA between the years of 1997 and 2016. Cases were stratified based on whether the patient received PVE. A multiple linear regression was used to predict the effect of PVE on hospital length of stay (LOS) and total cost while controlling for patient demographic factors and comorbidities. The odds ratio (OR) of receiving a perioperative blood transfusion was computed using a binary logistic regression for PVE patients. Results  A total of 473 patients who underwent JNA surgical resection in this time period were identified. The use of PVE has increased from 0% in 1997 to 66% of all cases by 2016. PVE was found to decrease LOS by 1 day ( p  = 0.036) and decrease the odds of needing a perioperative blood transfusion (OR = 0.511, p  = 0.041). Patients receiving PVE were charged an additional $35,600 ( p  < 0.001), but recent data in 2016 indicate that hospital costs for PVE are decreasing. Conclusion  PVE of JNA is becoming increasingly prevalent. Embolization results in decreased hospital LOS and lower odds of needing blood transfusions. While embolization increases the cost of management, this trend should be re-evaluated as this procedure is becoming more widespread.

    Somatostatin receptors (SSTRs) are highly expressed in neuroendocrine tumors and is exploited for its imaging and treatment. SSTRs expression is also demonstrated in diverse benign and malignant tumor cell types and proliferating peri-tumoral vessels. Similarly, Juvenile Nasopharyngeal Angiofibroma (JNA) expresses different SSTRs and may be utilized for its imaging and treatment using DOTA, 1-Nal3-octreotide (DOTANOC)-PET/CT scan.
    Prospective cohort.
    Nineteen clinico-radiologically diagnosed primary JNA patients underwent a 68 Ga-DOTANOC PET-CT scan. Using a dedicated PET/CT scanner, a low-dose head and neck spot CT scan was performed after 45 to 60 minutes of intravenous injection of 2 to 3 mCi(74-111 MBq) of DOTANOC. The primary objective was to assess the intensity and pattern of DOTANOC uptake in these patients.
    DOTANOC expression was noted in all cases (n = 19) of primary JNA (100%). The mean (SD) DOTANOC SUVmax ratio of tumor and background was 6.9+/-1.4(range, 3.8-9.5). Intra-cranial extension in all 13/19 patients was prominently visualized due to the absence of DOTANOC uptake in the brain. Compared to the background all stages of JNA showed significant DOTANOC uptake (P < .0001). No difference in uptake between advanced-stage tumors and early tumors was noted (P = .47). A statistically non-significant negative trend was noted for decreasing uptake with increasing age (Spearman correlation coefficient, r = -0.19).
    This first study of 68 Ga-DOTANOC-PET/CT scan in JNA demonstrates consistent and reliable uptake activity in all patients irrespective of age and stage. This opens up possibilities to physiological diagnostic imaging with a promise of greater specificity and sensitivity and may have applications in ambivalent diagnostic situations such as the detection of recurrence.
