Carcinoma de intervalo en un programa de cribado de cáncer de mama (2007-2018). Características y pronóstico 乳腺癌筛查计划中的间期癌(2007-2018 年)。特征和预后
IF 1.1 Q3 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING Pub Date : 2024-11-01 DOI: 10.1016/j.rx.2023.03.005

Background and aims

To analyze the radiologic and histologic characteristics of screening and interval cancers diagnosed in the period comprising 2007 through 2018 in a total of six rounds of a population-based breast cancer screening program.

Material and methods

We analyzed 1395 carcinomas detected at screening and 300 interval carcinomas diagnosed in women aged 50 to 69 years old who underwent digital mammography every two years during the study period. Screening mammograms were read once.
To classify the interval carcinomas, we retrospectively reviewed (blind reading followed by unblinded reading) at the end of each round, recording the radiologic findings, breast density, histologic characteristics, phenotype, and surgical treatment.

Results

The interval carcinomas were classified as true interval cancers in 156 (52%) cases, false-negatives in 62 (20.5%), minimal signs in 39 (13%), occult lesions in 29 (9.5%), and impossible to classify in 14 (5%).
Retrospectively, the most common radiologic findings in the false-negative cases were mass/asymmetry (64%), calcifications (16%), and distortion (13%); the most common radiologic findings in the cases with minimal signs were mass/asymmetry (58%) and calcifications (31%).
There were significant differences in the histologic characteristics between cancers detected at screening and interval cancers: T1a-b (9% of the interval cancers vs. 34% of those detected at screening; P < .001); T1c (30% of the interval cancers vs. 44% of those detected at screening; P < .001); T2 or greater (61% of the interval cancers vs. 22% of those detected at screening; P < .001), and the degree of axillary involvement (45% of the interval cancers vs. 27% of those detected at screening; P < .001).
There were also significant differences between cancers detected at screening and interval cancers in the proportion of cases with more aggressive subtypes (HER2+ and triple-negative): 38.5% of the interval cancers vs. 23% of those detected at screening; P < .001.
A significantly higher proportion of interval cancers were treated with mastectomies (80% vs. 67% of those detected at screening; P < .001).

Conclusions

About 20% of interval cancers were evident on screening mammograms. The most common radiologic finding in interval cancers was asymmetry/mass. Interval cancers are diagnosed at a more advanced stage than cancers identified at screening, so they are more often treated by mastectomy. Reviewing interval cancers is essential for quality control in screening programs.
背景和目的分析2007年至2018年期间,在一项基于人群的乳腺癌筛查计划中,共进行了六轮筛查和间期癌症诊断的放射学和组织学特征。材料和方法我们分析了在筛查中发现的1395例癌症和300例间期癌症,这些癌症发生在研究期间每两年接受一次数字乳腺X光检查的50至69岁女性中。为了对间期癌进行分类,我们在每一轮检查结束后进行了回顾性复查(盲阅后进行非盲阅),记录了放射学检查结果、乳腺密度、组织学特征、表型和手术治疗。回顾性研究发现,在假阴性病例中,最常见的放射学发现是肿块/不对称(64%)、钙化(16%)和变形(13%);在征象极少的病例中,最常见的放射学发现是肿块/不对称(58%)和钙化(31%):筛查发现的癌症与间期癌症的组织学特征存在明显差异:T1a-b(9% 的间期癌症与 34% 的筛查发现的癌症相比;P < .001);T1c(30% 的间期癌症与 44% 的筛查发现的癌症相比;P < .001);T2 或以上(61% 的间期癌症与 22% 的筛查发现的癌症相比;P < .在更具侵袭性亚型(HER2+ 和三阴性)的病例比例方面,筛查发现的癌症与间期癌症也存在显著差异:间期癌症中接受乳房切除术治疗的比例明显更高(80% 对比起筛查发现的 67%;P <.001)。结论约 20% 的间期癌症在筛查乳房 X 光检查中很明显。间期癌最常见的放射学发现是不对称/肿块。与筛查发现的癌症相比,间期癌的诊断处于更晚期,因此更常采用乳房切除术进行治疗。复查间期癌对于筛查项目的质量控制至关重要。

Fractura ósea tras un traumatismo menor en la enfermedad de Pyle: un caso poco frecuente en un adulto 派尔氏病轻微外伤后骨折:一例罕见的成人病例。
IF 1.1 Q3 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING Pub Date : 2024-11-01 DOI: 10.1016/j.rx.2023.08.004
Pyle's disease (PD) is a rare autosomal recessive metaphyseal dysplasia with approximately 30 reported cases and has recently gained interest due to its association with specific genes. While most cases are diagnosed in childhood and are asymptomatic, we present the case of a 39-year-old woman who presented to the Emergency Department with left knee pain, patellar fracture, and «Erlenmeyer flask» deformity. Retrospective review of imaging studies and medical history revealed the symmetric and systemic nature of the skeletal disorder, confirming the diagnosis of PD. Familiarity with this disease is crucial for optimal patient management, and the radiologist plays a crucial role in its diagnosis.
派尔氏病(Pyle's disease,PD)是一种罕见的常染色体隐性遗传骺发育不良症,目前约有 30 例病例报道。虽然大多数病例在儿童时期被诊断出来并且没有症状,但我们现在介绍的病例是一名 39 岁的女性,她因左膝疼痛、髌骨骨折和 "埃伦梅耶烧瓶 "畸形而到急诊科就诊。对影像学检查和病史的回顾性分析表明,该骨骼疾病具有对称性和系统性,因此确诊为帕金森病。熟悉这种疾病对患者的最佳治疗至关重要,而放射科医生在诊断中起着关键作用。

Presentaciones atípicas de los procesos linfoproliferativos primarios del sistema nervioso central 中枢神经系统原发性淋巴细胞增生过程的非典型表现
IF 1.1 Q3 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING Pub Date : 2024-11-01 DOI: 10.1016/j.rx.2024.05.003
Central nervous system (CNS) involvement by lymphoproliferative disorders is rare and associated with a poor prognosis. CNS involvement can be exclusive, primary or appear in a secondary manner as part of a systemic process. The spectrum of involvement that we encounter is varied and neuroimaging plays a key role in diagnosis. This article reviews less commonly presented patterns of primary involvement of CNS lymphoproliferative processes such as lymphomatosis cerebri, intravascular lymphoma or dural lymphoma. We will also review other atypical lymphoproliferative processes associated with Epstein-Barr virus (EBV) infection, such as lymphomatoid granulomatosis (LG) or post-transplant lymphoproliferative disorders (PTLD). An awareness of these patterns of presentation and less frequent entities will allow us to make earlier diagnoses and establish treatments that will lead to better prognoses for patients.
淋巴组织增生性疾病累及中枢神经系统(CNS)的情况十分罕见,且预后不良。中枢神经系统受累可以是排他性的、原发性的,也可以作为全身过程的一部分继发出现。我们遇到的累及范围多种多样,神经影像学在诊断中起着关键作用。本文将综述中枢神经系统淋巴增生过程中较少见的原发性受累模式,如脑淋巴瘤病、血管内淋巴瘤或硬脑膜淋巴瘤。我们还将综述与爱泼斯坦-巴氏病毒(EBV)感染相关的其他非典型淋巴增生过程,如淋巴瘤样肉芽肿病(LG)或移植后淋巴增生性疾病(PTLD)。对这些表现形式和不常见实体的认识将使我们能够更早地做出诊断并确立治疗方法,从而为患者带来更好的预后。

IF 1.1 Q3 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING Pub Date : 2024-11-01 DOI: 10.1016/j.rx.2023.01.011

Objective

To demonstrate the safety and efficacy of endovascular treatment in postpartum hemorrhage.

Material and methods

We conducted a retrospective observational study with a sample from our Interventional Vascular Radiology unit, from 2004 to 2020. Patients who developed postpartum hemorrhage treated by arterial embolization were selected. Inclusion criteria were established to standardize the study group. Variables for the study of the efficacy and safety of the technique are defined.

Results

The final sample of the study was 56 patients. Technical success turned was 100%, while clinical success after endovascular treatment was 92.85%, with a hysterectomy rate due to failed arterial embolization of 7.14%, with uterine rupture observed in 3 cases as a cause of postpartum hemorrhage. No technique-related mortality was recorded. The rate of periprocedural complications was 3.56%, the same as that of late complications. No major or infectious complications were recorded. The pregnancy rate after embolization was 23.52%.

Conclusions

Selective arterial embolization of the uterine artery in postpartum hemorrhage is a safe and effective procedure, being a therapeutic alternative in the face of failure of pharmacological and obstetric management, with preservation of fertility.

Acute rhinossinusitis is defined as a symptomatic inflammation of the nasal fossa and paranasal sinuses. The diagnosis of this disease is clinical and usually does not require imaging evaluation. However, when there is a suspicion of a complication or even for surgical planning, imaging is of primordial importance.
The aim of this paper is to provide a concise pictorial review with clinical and imagiological correlation of the most common complications in acute rhinossinusitis to provide relevant clinical data and highlight the most important imaging findings.

Adenocarcinoma de pulmón: Presentaciones radiológicas características 肺腺癌:特征性放射学表现
IF 1.1 Q3 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING Pub Date : 2024-11-01 DOI: 10.1016/j.rx.2023.07.007
Radiology, mainly computed tomography, has a fundamental role in diagnosis, staging and follow-up of lung adenocarcinoma, the most common type of pulmonary cancer. Within its broad spectrum of presentation, the pathological, clinical and morphological characteristics of this neoplasm allow, in an appropriate clinical context, to suggest certain histological subtypes among which are mucinous adenocarcinoma, lepidic growth adenocarcinoma or associated with cystic lung lesions. The objective of this review is to describe the pathologic, clinical and radiological features of those characteristic forms of lung carcinoma that can be diagnosed radiologically with fair accuracy.
放射学,主要是计算机断层扫描,在肺腺癌(最常见的肺癌类型)的诊断、分期和随访方面发挥着重要作用。肺腺癌的病理、临床和形态特征表现范围广泛,在适当的临床环境下,可以提出某些组织学亚型,其中包括粘液腺癌、鳞状生长腺癌或伴有囊性肺病变的肺腺癌。本综述旨在描述可通过放射学诊断的肺癌的病理、临床和放射学特征。
