Emphysematous osteomyelitis is an extremely rare entity consisting of the presence of intraosseous gas that can extend to the joints and adjacent soft tissues. It is an aggressive infectious process associated with high mortality, especially in patients with risk factors such as tumors or diabetes mellitus. Because early diagnosis and immediate treatment are crucial to prevent the potentially devastating consequences of this condition, imaging tests such as computed tomography play a fundamental role in its diagnosis and management. Therefore, radiologists must be aware that intraosseous gas is a rare but alarming sign that is pathognomonic of emphysematous osteomyelitis, especially in the axial skeleton.

Objective
Calcific tendinopathy of the rotator cuff is a common condition caused by the deposition of calcium crystals in the tendons of the rotator cuff. This study aimed to analyze the effectiveness of ultrasound-guided puncture and aspiration in calcific tendinopathy of the should in 86 patients treated at our center and to determine the factors associated with poor prognosis after this treatment.
Material and methods
This retrospective descriptive study included 86 patients with calcific tendinopathy of the rotator cuff treated with ultrasound-guided puncture and aspiration between 2015 and 2019 for whom clinical and radiological variables were collected 1, 3, 6, and 12 months after the procedure.
Results
One year after treatment, 81.4% patients showed clinical improvement and 96.5% showed radiological improvement. Complications were observed in 34.9%; all complications were mild.
Conclusions
Ultrasound-guided puncture and aspiration is an effective treatment for calcific tendinopathy of the shoulder, resulting in a high rate of clinical and radiological improvement and a low rate of minor complications. This technique has additional advantages, such as interaction with the patient and the lack of ionizing radiation.

Objective
To evaluate differences in measurements of the lateral recesses and foramina in degenerative lumbar segments on MR images in symptomatic patients obtained with the patient standing versus lying down and to analyze the relationship between possible differences and patients’ symptoms.
Material and Methods
We studied 207 disc levels in 175 patients aged between 17 and 75 years (median: 47 years) with low back pain. All patients underwent MRI in the decubitus position with their legs extended, followed by MRI in the standing position. We calculated the difference in the measurements of the lateral recesses (in mm) and in the foramina (area in mm2 and smallest diameter in mm) obtained in the two positions. To eliminate the effects of possible errors in measurement, we selected cases in which the difference between the measurements obtained in the two positions was ≥10%; we used Student's t-tests for paired samples to analyze the entire group and subgroups of patients according to age, sex, grade of disc degeneration, and postural predominance of symptoms.
Results
Overall, the measurements of the spaces were lower when patients were standing. For the lateral recesses, we observed differences ≥10% in 68 (33%) right recesses and in 65 (31.5%) left recesses; when patients were standing, decreases were much more common than increases (26% vs. 7%, respectively, on the right side and 24% vs. 7.5%, respectively, on the left side; p< 0.005). For the foramina, decreases in both the area and in the smallest diameter were also more common than increases when patients were standing: on the right side, areas decreased in 23% and increased in 4%, and smallest diameters decreased in 20% and increased 6%; on the left side, areas decreased in 24% and increased in 4%, and smallest diameters decreased in 17% and increased in 8% (p< 0.005). Considering the group of patients in whom the postural predominance of symptoms was known, we found significant differences in patients whose symptoms occurred predominantly or exclusively when standing, but not in the small group of patients whose symptoms occurred predominantly while lying. We found no differences between sexes in the changes in measurements of the recesses or foramina with standing. The differences between the measurements obtained in different positions were significant in patients aged >40 years, but not in younger groups of patients. Differences in relation to the grade of disc degeneration were significant only in intermediate grades (groups 3-6 in the Griffith classification system).
Conclusion
MRI obtained with patients standing can show decreases in the lateral recesses and foramina related to the predominance of symptoms while standing, especially in patients aged >40 years with Griffith disc degeneration grade 3 to 6, thus providing additional in

Introduction and objectives
This study aimed to examine the clinical utility of the radiographic evaluation of the bicipital groove in predicting long head of biceps tendon (LHBT) pathology.
Material and Methods
A prospective study was conducted, and sixty consecutive patients proposed to shoulder arthroscopic surgery were selected. Before surgery, a radiographic evaluation was performed with a supine and a Fisk radiograph. Most supine radiographs (>75%) were non-interpretable and were excluded from the study. As some Fisk radiographs (26.7%) were also non-interpretable, that left 44 interpretable radiographs in the study. These were measured for medial opening angle, total opening angle, width and depth of the bicipital groove. The radiographic measurements and the presence of LHBT pathology, as assessed at arthroscopy, were correlated.
Results
Radiographic evaluation of the bicipital groove showed a mean medial opening angle of 53 ± 15o (23 – 90), a mean total opening angle of 80 ± 26o (30 – 135), a mean width of 10.3 ± 2.5 mm (6 – 19) and a mean depth of 4.1 ± 1.5 mm (1 – 8). Men had higher medial opening angle (60 vs 50o, p = 0.044) and wider grooves (11.9 vs 9.7 mm, p = 0.019). Twenty-five patients (56.8%) were found to have an abnormal LHBT. No correlation was found between the radiographic measurements and LHBT pathology. Only age was correlated with a LHBT lesion (61.8 vs 46.3 years, p < 0.001).
Conclusions
Our results show that there is no correlation between radiographic morphologic evaluation of the bicipital groove and LHBT pathology.

Background and aims
Myxoid liposarcoma is classified in the group of sarcomas with adipose differentiation, which is the second most common group of sarcomas. However, myxoid liposarcoma is not a homogeneous entity, because the behavior and clinical course of these tumors can vary widely. This study aimed to describe the magnetic resonance imaging (MRI) features of myxoid liposarcomas and to determine whether the MRI features are associated with the histologic grade and can differentiate between low-grade and high-grade tumors and thus help in clinical decision making.
Material and methods
We studied 36 patients with myxoid liposarcomas treated at our center between 2010 and 2018. We analyzed clinical variables (age, sex, and tumor site) and MRI features (size, depth, borders, fatty component, myxoid component, non-fatty / non-myxoid component, apparent diffusion coefficient (ADC), and type of enhancement after the administration of intravenous contrast material). We correlated the MRI features with the histologic grade and the percentage of round cells.
Results
In our series, patients with myxoid liposarcomas were mainly young adults (median age, 43 years). There were no differences between sexes; 97.2% were located in the lower limbs, 86.1% were deep, and 77.8% had well-defined borders. Of the 23 myxoid liposarcomas that contained no fat, 16 (69.6%) were high grade (p = 0.01). All the tumors with a myxoid component of less than 25% were high grade (p = 0.01); 83.3% of those with a non-fatty / non-myxoid component greater than 50% were high grade (p = 0.03) and 61.5% had more than 5% round cells (p = 0.01). Diffusion sequences were obtained in 14 of the 36 patients; ADC values were high (median, 2 x 10-3 mm2/s), although there were no significant associations between low-grade and high-grade tumors. Contrast-enhanced images were available for 30 (83.3%) patients; 83.3% of the tumors with heterogeneous enhancement were high grade (p = 0.01).
Conclusions
MRI can be useful for differentiating between high- and low-grade myxoid liposarcomas and can help in clinical decision making.
背景与目的黏液样脂肪肉瘤属于脂肪分化型肉瘤，是第二常见的肉瘤。然而，黏液样脂肪肉瘤并不是一个单一的实体，因为这些肿瘤的行为和临床过程可能有很大的差异。本研究旨在描述黏液样脂肪肉瘤的磁共振成像（MRI）特征，并确定MRI特征是否与组织学分级有关，是否可以区分低级别和高级别肿瘤，从而有助于临床决策。材料和方法我们研究了2010年至2018年间在我们中心接受治疗的36例黏液样脂肪肉瘤患者。我们分析了临床变量（年龄、性别和肿瘤部位）和MRI特征（大小、深度、边界、脂肪成分、黏液成分、非脂肪/非黏液成分、表观扩散系数（ADC）和静脉注射造影剂后的增强类型）。我们将MRI特征与组织学分级和圆形细胞百分比相关联。结果在我们的系列中，黏液样脂肪肉瘤患者主要是年轻人（中位年龄43岁）。性别之间没有差异；97.2%位于下肢，86.1%位于深部，77.8%边界清晰。在23例不含脂肪的黏液样脂肪肉瘤中，16例（69.6%）为高级别（p＝0.01）。黏液样成分低于25%的肿瘤均为高级别肿瘤（p＝0.01%）；非脂肪/非黏液成分大于50%的患者中，83.3%为高级别（p=0.03），61.5%为圆形细胞（p=0.01）。36例患者中有14例获得了扩散序列；ADC值较高（中位数为2 x 10-3 mm2/s），尽管低级别和高级别肿瘤之间没有显著关联。30例（83.3%）患者可获得对比度增强图像；83.3%的肿瘤为高级别（p＝0.01）。结论mri有助于区分高级别和低级别黏液样脂肪肉瘤，并有助于临床决策。

Granular cell tumors are histologically unique neoplasms that often manifest as painless solitary nodules located in the dermis or submucosal tissue. In this article we analyze the radiologic features of this type of tumor in five patients by magnetic resonance imaging (MRI), analyzing morphologic and signal characteristics. MR imaging findings were similar to other publications and we demonstrate low ADC values in our series.

Intraneural ganglion cysts are very uncommon lesions that are starting to be diagnosed thanks to the establishment of the articular theory to explain their pathogenesis and to the definition of their signs on magnetic resonance imaging (MRI). We present the case of a 59-year-old man with clinical findings suggestive of tarsal tunnel syndrome. MRI of the ankle and foot showed an intraneural ganglion cyst involving the posterior tibial nerve and its connection with the subtalar joint through an articular nerve branch. The appropriate interpretation of specific radiologic signs such as the “signet ring sign” enabled an appropriate preoperative diagnosis to be established, differentiating it from an extraneural lesion and facilitating the articular disconnection of the nerve branch during surgery.

Meningiomas are tumors that originate in the arachnoid villi and are the most common non-glial neoplasm in the central nervous system. The clinical manifestations associated with meningioma depend, fundamentally, on its location. The location in the cerebral convexity is the most frequent, especially in the frontal lobes, manifesting with headache, motor disturbances, seizures and even neurocognitive disorders. There are 15 histologic subtypes of meningioma and three histologic grades. Within these, grades two and three have a worse prognosis and a higher rate of recurrence, as well as a radiological behavior that is generally more aggressive. Although there are some imaging features that can suggest a specific subtype, the definitive diagnosis will always require histological/molecular confirmation.

Image acquisition involves the use of static magnetic fields, field gradients and radiofrequency waves. These elements make the MRI a different modality. More and more centers work with 3.0 T equipment that present higher risks for the patient, compared to those of 1.5 T.
Therefore, there is a need for updating for radiology staff that allows them to understand the risks and reduce them, since serious and even fatal incidents can occur.
The objective of this work is to present a review and update of the risks to which patients are subjected during the performance of a magnetic resonance imaging study.
