肝脏紫癜病超声表现一例

患者女，21岁，因脐周持续性疼痛伴腹泻6个月，发现腹腔占位病变10d入院。患者既往无肝炎，黄疸及发热病史，6个月前，脐周持续性疼痛，伴有黄色稀水样便，每天4～5次。实验室检查：甲胎蛋白（AFP）、C11—9，乙肝6项，丙肝检查均无异常。查体发现右上腹可触及～大小约20mm×15mm×15mm包块，质硬，有触痛，表面光滑，不活动。     

肝脏结核的CT及MRI诊断

腹部结核约占肺外结核的3.5%,以淋巴结受累最为多见,而实质脏器受累仅占15%~20%,其中又以泌尿系最为常见,其次为肝脏[1]。肝脏结核(肝结核)既往曾被称为结核性肝炎、结核性炎性假瘤、结核性胆管炎、肝浆膜结核等,其影像表现缺少特异性,与肝脏其他感染性病变及肿瘤性病变的影像学征象多有重叠,诊断颇具挑战性[2-4]。本文着重就肝结核的CT及MRI表现作一论述,旨在加深临床

肝脏增强CT与肝脏MRI在诊断肝癌的临床价值比较

选取我院收治的104例肝癌患者为研究对象,按入院时间先后将其随机分为两组各52例。对照组采用肝脏增强CT检测,观察组采用肝脏MRI检测,对比分析诊断效果。观察组的诊断准确率为96.15%,对照组的诊断准确率为84.62%,两组组间有显著差异(P0.05)。在肝癌上的临床诊断上,肝脏MRI的诊断价值高于肝脏增强CT,临床诊断准确率相对较高可为临床诊断和治疗提供重要依据,因此,更具有临床应用和推广价值。     

肝脏增强CT与肝脏MRI在诊断肝癌准确率方面的比较

目的:比较肝脏增强CT与肝脏MRI诊断肝癌的准确率。方法:纳入我院2017年11月—2019年11月经穿刺活检及病理诊断确诊为肝癌的96例患者,采取分组方式进行对比研究,以“随机双盲法”将纳入主体分为两组,包括对比组(48例,进行肝脏增强CT检查)与研究组(48例,采取肝脏MRI检查),比较诊断准确性。结果:研究组诊断准确率高于对比组,肝内病变灶数、肝外病变灶数多于对比组,差异显著,P<0.05。结论:在肝癌患者检查诊断中,肝脏MRI诊断准确率、检查病变结果等均比增强CT更加理想,更具优势,能够为临床治疗提供更加可靠的依据,值得在肝癌诊断中推广,但是,两种检查诊断方式诊断准确率均存在一定误差,因此,为进一步提高肝癌诊断准确率,应结合实验室等其他辅助检查手段。     

探讨肝脏增强CT与肝脏MRI在肝癌诊断中的应用价值

对2013年1月~2015年1月我院收治的64例原发性肝癌患者的临床资料进行回顾性分析,所有患者均经组织病理学证实,将患者肝脏增强CT与肝脏MRI影像学结果与病理学结果对比,评价两种检查方法的诊断价值。结果CT诊断符合率为75.00%,MRI诊断符合率为96.88%,两种检查方法诊断符合率差异显著(P<0.05)。肝脏增强CT与肝脏MRI在肝癌诊断中均有较高应用价值,但肝脏MRI在诊断准确率更高,特别直径≤3cm的肿瘤中,可在临床上推广。     

肝脏增强CT与肝脏MRI在诊断肝癌准确率方面的对比分析

目的:研究比较肝癌诊断中肝脏增强CT与肝脏MRI的准确率。方法:病例样本为2018年9月-2019年9月时间段我院收治的86例疑似肝癌患者,所有患者均实施肝脏增强CT检查与肝脏MRI检查,将病理检查结果作为金标准,研究比较肝脏增强CT与肝脏MRI诊断准确率。结果:评估肝内病灶及肝外病灶检出数,肝脏增强CT均低于肝脏MRI(P<0.05)。以病理检查结果为金标准,评估肝脏增强CT与肝脏MRI诊断不同病理类型肝癌的准确率,肝脏MRI高于肝脏增强CT(P<0.05)。结论:肝脏增强CT及肝脏MRI均属临床常用肝癌诊断方式,肝脏MRI诊断准确率高于肝脏增强CT值得临床推广应用。     

肝脏增强CT与肝脏MRI在肝癌诊断中的应用价值

选取我院2013年1月~2015年10月收治的103例肝癌患者,全部患者均先后行肝脏增强CT扫描检查和肝脏MRI检查,并对比分析两种检查方法的诊断效果。结果结合病理学结果可知,MRI检查所获得的诊断符合率达到95.12%,明显高于CT检查的88.35%,差异有统计学意义(P0.05);在直径3cm的肿瘤检测中,MRI的检出率为96.77%,与CT检查的87.10%相比较高,差异有统计学意义(P0.05)。肝脏MRI在肝癌诊断中准确性更高,尤其是直径3cm肿瘤的检测上,可以获得更为可靠的诊断结果,值得推广。     

肝脏增强CT技术与肝脏MRI技术诊断肝癌的准确率比较研究

目的:探讨肝脏增强CT技术与MRI技术对肝癌的诊断价值。方法:选取泰州市第二人民医院2021年1月—2022年8月收治的58例肝癌患者,分别开展肝脏增强CT与MRI检查,以病理诊断结果为金标准,分析两种影像学技术的影像学征象,并比较两种技术对不同直径病灶的检出率。结果:CT增强扫描时动脉期52例病灶强化明显,病灶密度比正常肝组织明显更高;门脉期扫描55例病灶为等密度,延迟期扫描均为低密度病灶且强化程度呈现出下降态势;MRI平扫时T₁WI信号低,增强扫描时动脉期强化明显,门脉期扫描52例病灶等信号,延迟期扫描55例为低信号。病理诊断结果显示58例肝癌患者中41.38%为肝细胞性肝癌,34.48%为胆管细胞肝癌,24.14%为混合性肝癌,其中MRI的诊断符合率为96.55%,高于增强CT的79.31%,差异有统计学意义(P <0.05)。结论:肝脏增强CT与肝脏MRI诊断肝癌均有其优缺点,相较于增强CT,MRI诊断肝癌的检出率更高,更有利于开展病理分型,对临床诊断及早期制定治疗方案的指导意义更加明显,更具推广价值。但MRI仍然无法完全取代增强CT,临床可结合实际...

Imaging presentation and postoperative recurrence of peliosis hepatis: A case report

BACKGROUNDPeliosis hepatis (PH) is a rare benign lesion of vascular origin with a pathological characteristic of multiple blood-filled cavities in the liver parenchyma. It is commonly misdiagnosed due to its lack of specificity in clinical presentation and laboratory test results. Herein, a case of a patient with PH who was misdiagnosed with hepatic echinococcosis before operation to remove the lesions was analyzed, with an emphasis on the computed tomography and magnetic resonance imaging characteristics of PH.CASE SUMMARYWe outline the case of a 40-year-old Chinese female who was admitted with aggravated abdominal pain with fever for 1 wk. Ultrasound examination at the local hospital indicated hepatic echinococcosis. However, discordance between imaging diagnosis, clinical history and laboratory examinations in our hospital. Subsequently, the patient was pathologically confirmed as having PH-like changes, which recurred 1 year after operation removal of the lesion. CONCLUSIONOur objective is to highlight the imaging diagnostic value of PH.     

Hepatic peliosis (bacillary angiomatosis) in AIDS: CT findings

Patients with acquired immunodeficiency syndrome are at risk of developing opportunistic infections and aggressive tumors. Computed tomographic examination is the usual method of evaluating the abdomen and pelvis in these patients. Although this technique is reasonably sensitive in detecting pathology, findings are often nonspecific. A case of hepatic peliosis (bacillary angiomatosis) in a patient with acquired immunodeficiency syndrome is presented.     

Needle orientation for transhepatic cholangiography: CT localization of the porta hepatis

The needle orientation recommended for transhepatic cholangiography has a consensus in the literature for the sagittal and the transverse planes. Because of differing recommendations for the needle orientation in the coronal plane, the location of the porta hepatis was analyzed in 50 patients undergoing computed tomography. The mean ratio between skin to the porta hepatis distance and AP patient diameter is 0.38. The best puncture site therefore lies anteriorly to the halfway mark at the midaxillary line by about 3 cm.     

Primary malignant lymphoma in the porta hepatis: a case report

A case of primary lymphoma in the porta hepatis is presented here. Cholangiography, angiography, ultrasonography and computed tomography suggested the presence of a mass in the porta hepatis, but all these failed to demonstrate the tumor clearly. Magnetic resonance imaging was very useful in defining the characteristics of the tumor and in delineating its extent, though it was not specifically diagnostic.

Ruptured splenic peliosis in a patient with no comorbidity: A case report

BACKGROUND Splenic peliosis is a disease characterized by widespread blood-filled cystic cavities within the parenchyma. Patients with this disease are usually asymptomatic;therefore, spontaneous or trauma-related rupture of the hemorrhagic cysts can occasionally cause life-threatening hemorrhagic shock.CASE SUMMARY A 51-year-old male patient with abdominal pain visited our emergency medical center two times with an interval of 2 mo. The patient was discharged from the hospital without treatment at his first visit;however, at the time of second admission, the hemoperitoneum with multiple cystic lesions of the spleen was found incidentally on the abdomen computed tomography scan. Since the patient was stable hemodynamically, a scheduled surgery was performed. The operative findings were consistent with splenic peliosis, and laparoscopic splenectomy was performed to prevent recurrent rupture of the hemorrhagic cysts.CONCLUSION Splenic peliosis is extremely rare, and we suggest splenectomy is necessarily required as a definite treatment for ruptured splenic peliosis to rescue patients with hemodynamic instability and to prevent recurrent rupture of hemorrhagic cysts in patients with stable hemodynamics.
