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.

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 50–69 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 sre more often treated by mastectomy. Reviewing interval cancers is essential for quality control in screening programs.
背景与目的分析在 2007 年至 2018 年期间共六轮基于人群的乳腺癌筛查计划中诊断出的筛查癌和间期癌的放射学和组织学特征：我们分析了研究期间每两年接受一次数字乳腺X光检查的50-69岁女性中筛查出的1395例癌症和诊断出的300例间期癌症。筛查乳房 X 光照片只读一次。为了对间期癌进行分类，我们在每一轮检查结束后进行回顾性复查（盲阅后进行非盲阅），记录放射学检查结果、乳腺密度、组织学特征、表型和手术治疗：156例（52%）间期癌被归类为真正的间期癌，62例（20.5%）为假阴性，39例（13%）为极小征象，29例（9.5%）为隐匿性病变，14例（5%）无法归类。回顾性分析发现，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%）；在征兆极少的病例中，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隔期癌症的组织学特征存在明显差异：T1a-b[占间期癌的 9%，占筛查发现癌的 34%，P 结论：T1a-b[占间期癌的 9%，占筛查发现癌的 34%：约 20% 的间隔期癌症在筛查乳房 X 光照片中明显可见。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，因此更多情况下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。

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.

Objective
To demonstrate the safety and efficacy of endovascular treatment in postpartum hemorrhage (PPH).
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 PPH and another case was a placenta accreta. 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 PPH is a safe and effective procedure, being a therapeutic alternative in the face of failure of pharmacological and obstetric management, with preservation of fertility.

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.

Introduction and objectives
The increasing participation of radiologists in multidisciplinary boards brings about advantages, challenges and specific needs. The aim of this paper is to identify the boards in which radiologists participate and to detect the needs, problems and opportunities that these boards pose for our specialty.
Methods and materials
The Spanish Society of Medical Radiology (SERAM) conducted an ad-hoc survey that was distributed among members and through social networks. The results were analysed with Stata® v14.2 (StataCorp, Texas, USA).
Results
Between 15 November 2022 and 24 December 2022, we received 743 anonymous responses with 93.7% coming from SERAM members (642 radiologists and 101 radiology trainees). Among the specialists, 82.7% regularly participate in one or more boards (92.5% oncology/50.7% non-oncology/43.3% both), which implies two or more meetings per week for 41.6% of the respondents.
Both radiologists who regularly participate in boards and those who do not, are very positive about this aspect of professional activity and agree on its benefits. However, the specialists who do participate, lack enough allocated time and information to prepare cases prior to the meeting. Although attendance is often recorded (69.7%), it is generally not included in the work plan (20.5% of physicians and 30.8% of middle managers, p = 0.028).
Regarding operational functioning, according to 46.9% of respondents there is no record of imaging tests reviewed, and the handling of discrepancies within radiology departments is poor (written recommendations and review sessions are only available to 14.3% and 7.7% of respondents respectively).
Conclusions
The radiologists surveyed report the high impact of multidisciplinary committees on their workload and clinical decisions. They mention a number of problems, some of which are specific to radiology, which can undermine efficiency and safety. These include work organisation, lack of time and problems of accessibility and the recording of imaging tests and other medical record data.

Spectral computed tomography has represented a major breakthrough in radiology thanks to its multiple applications and potential to provide more information than conventional CT techniques. It is very useful for diagnosing and describing findings as well as the management of patients, thus avoiding further imaging or invasive procedures.
The aim of this article is to explain basic concepts of spectral CT and highlight key practical features in a range of abdominal and pelvic pathologies, along with a brief description of different post-processing maps and their clinical applications including incidental, oncological and urgent findings.

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.

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.</div></div>","PeriodicalId":94185,"journal":{"name":"Radiologia","volume":"66 6","pages":"Pages 555-563"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142824944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
