Abstract
OBJECTIVE This article aimed to describe the common imaging features of subungual glomus tumors. METHODS The study involved data collected between January 2019 and December 2022. Twenty-three patients with a total of 31 glomus tumors underwent high-frequency ultrasound examinations with a 24-MHz probe. Two experienced radiologists independently evaluated the images, and only data from the more experienced radiologist were used for subsequent analyses. RESULTS The average size of the tumors was 4.6 mm, and most of them appeared homogeneously hypoechogenic (90.3%). Bone remodeling of the distal phalanx was observed in 87.1% of cases, with an average axial circumference loss of 0.8 mm, indicating the slow and expansive growth of glomus tumors. Intense vascularization was found in 54.8% of cases on Doppler images, and the stalk sign, reflecting the vascular origin of the tumor, was present in 64.5% of cases. The most common clinical feature was pain, reported in 84.6% of cases, with a mean pain scale score of 7.0, indicating a negative impact on patients' lives despite being benign tumors. CONCLUSION The study concludes that ultrasound evaluation is highly useful for diagnosing glomus tumors, especially when multiple findings, such as bone remodeling, hypervascularization, and the stalk sign, are present. This method allows for accurate diagnosis, observation of periungual structures, and proper surgical planning, ultimately reducing recurrence rates.

Abstract
Clinical manifestations of dermatological and musculoskeletal conditions can sometimes overlap, leading to confusion in diagnosis. Patients with nail and skin infections may undergo imaging examinations with suspicions of muscle, tendon, or joint injuries. Dermatological infections often involve soft tissues and musculoskeletal structures, and their etiology can range from fungi, bacteria, viruses, to protozoa. Relying solely on physical examination may not be sufficient for accurate diagnosis and treatment planning, necessitating the use of complementary imaging exams. The objective of this paper is to present and discuss imaging findings of the main infectious conditions affecting the nail apparatus and skin. The paper also highlights the importance of imaging in clarifying diagnostic uncertainties and guiding appropriate treatment for dermatological conditions.

Abstract
INTRODUCTION Onychopapilloma is a benign tumor presenting as an isolated benign warty distal matrix and bed lesion in association with longitudinal erythronychia for which no underlying cause can be identified. Diagnosis might be challenging due to other, more severe, causes of erythronychia. OBJECTIVES This study aimed to investigate the clinical and sonographic features of onychopapilloma using high-frequency ultrasound. METHODS Between February 2022 and May 2023, a cross-sectional study was conducted, involving 39 patients displaying clinical features suggestive of onychopapilloma. These patients were selected at random and underwent examination using high-frequency ultrasound. High-frequency ultrasound assessments of the nail unit were carried out using 33 MHz and 24 MHz high-frequency linear transducers. An experienced radiologist performed the ultrasound scans while participants assumed an orthostatic seated position. Subsequently, the collected ultrasound images were independently evaluated by two radiologists specializing in nail injuries, ensuring a blinded assessment. This evaluation aimed to provide comprehensive insights into the imaging characteristics of onychopapilloma. RESULTS High-frequency ultrasound revealed oval or linear hyperechoic masses located in the middle of the nail plate, without vascularity or posterior acoustic shadowing. Nail plate irregularity, thickening, and nail bed indentation were observed in some cases. These findings demonstrate that high-frequency ultrasound can aid in the diagnosis and surgical planning of onychopapilloma, providing detailed visualization of the lesion and surrounding structures. CONCLUSIONS This imaging method could represent a potential tool to differentiate onychopapilloma from other nail conditions, especially malignant neoplasms. However, further research is needed to validate these findings and assess long-term outcomes.

Abstract
Subungual glomus tumors often remain undiagnosed for several years with patients seeing an average of 2.5 dermatologists before the diagnosis is confirmed. We describe the use of biomodelling and 3D technologies that allows the detection of tumoral recurrences more easily, as well as providing supplementary information for the radiologist report, such as select anatomical structure analysis, images with 360° rotation and visualization in transparency mode for detailed anatomic analysis.

Abstract
Onychomatricoma is a primary benign neoplasm of the nail matrix. Currently, a limited number of cases have been reported, so it is still considered a rare neoplasia. However, it is debatable if this condition is underdiagnosed and underreported. Onychomycosis is an important differential diagnosis of onychomatricoma, and sometimes, both these conditions may even coexist in the same nail. As the tumor grows, tissue microenvironment is more vulnerable to dermatophytes. Probably, the altered keratin appears to be susceptible to fungal invasion. Careful clinical assessment and dermoscopic evaluation help nailing the diagnosis. Usually, total nail avulsion is the preferred therapeutic approach when they coexist. Herein, we present a case of a middle-aged woman with onychomycosis and onychomatricoma affecting a single fingernail. The proposed therapy was oral terbinafine for 6 months followed by a conservative surgery. There were dramatic changes in dermoscopic features after fungal treatment, which, to our knowledge, have not been previously reported.

Abstract
The patient, a 10-year-old female, was referred to the rheumatology clinic with a previous history of fever (39ºC), loss of appetite and polyarthritis of wrist, knees, and ankles. Symptoms were relieved only after using NSAIDs. After 6 months, the patient returned to our hospital with a 7-month history of weight loss and chronic arthritis (claudication and morning stiffness of 15 minutes) on ankles. Physical exam revealed suggestive signs of chronic arthritis with exuberant swelling and tenosynovitis of both ankles. Magnetic resonance imaging of ankles showed bilateral and symmetrical tibiotalar arthritis of extensors, flexors, and fibularis tendons. Right ankle synovial biopsy revealed no granulomas. Which is the most probably diagnostics?

Abstract
BACKGROUND Localized fat is a matter of great concern among individuals from today's society. Cryolipolysis is a noninvasive technique that have shown great results in reducing localized fat. AIMS To analyze the efficacy of cryoplipolysis on visible local fat reduction in submental region, arms, or male breast (pseudogynecomastia) in Brazilian subjects, and to assess possible factors associated with treatment success. METHODS Single-arm, nonrandomized trial, with volunteers from both genders with visible excess fat in the arms or submental region or men presenting pseudogynecomastia. Eligible subjects were submitted to physical, photographic, and ultrasound analysis before and three months after intervention. A single cryolipolysis session was performed using specific methods for each region, followed by a local massage for two minutes. Data were described as measures of central tendency and dispersion and measures of frequency. Reduction in measurements and factors associated with treatment success was analyzed using appropriate statistical tests. RESULTS Thirty-six subjects underwent one session of cryolipolysis in each area (22 subjects treated the arms, 20 the submental region and 9 the breast). In general, a mean reduction of 19.1% was observed. Significant differences were observed for almost all body parts analyzed. Body mass index was the only variable showing a significant relationship with intervention results. CONCLUSIONS Cryolipolysis is a useful noninvasive tool in reduction of visible localized fat in arms and submental region and of pseudogynecomastia. Obese subjects are not benefited by the treatment.

Abstract
Objective The purpose of this study was to determine whether chemical-shift magnetic
resonance imaging (MRI) could be useful in the diagnosis of osteoid osteoma
when clinical and radiological tumor features are inconclusive. Materials and Methods This retrospective study included 17 patients who underwent chemical-shift
MRI for the evaluation of osteoid osteoma. For all patients, two
musculoskeletal radiologists independently recorded signal intensities on
in-phase and out-of-phase images in the nidus of the tumor, in
abnormal-intensity bone marrow surrounding the lesion, and in
normal-appearing bone marrow. For each region, relative signal intensity
ratios were calculated by dividing out-of-phase by in-phase values. Relative
ratios > 1 were considered indicative of neoplastic lesions. Statistical
analysis was carried out to analyze the sample. Inter-observer and
intra-observer agreement for each imaging method were assessed using
intraclass correlation coefficients according to the Fleiss method and a
value > 0.65 was considered to indicate substantial agreement. Results The mean relative signal intensity ratios were 1.2 (range, 0.9-1.4) for the
nidus and 0.35 (range, 0.11-0.66) for the surrounding tissue; these values
differed significantly from the relative signal-intensity ratios for
normal-appearing bone marrow (p < 0.05). Conclusion Chemical-shift MRI is useful for the diagnosis and evaluation of osteoid
osteoma.

Abstract
Neoplasms of neurogenic origin account for about 12% of all benign and 8% of all malignant soft tissue neoplasms. Traumatic neuroma, Morton neuroma, lipomatosis of a nerve, nerve sheath ganglion, perineurioma, benign and malignant peripheral nerve sheath tumors (PNST) are included in this group of pathologies. Clinical and radiologic evaluation of patients with neurogenic tumors and pseudotumors often reveals distinctive features. In this context, advanced imaging techniques, especially ultrasound (US) and magnetic resonance (MR) play an important role in the characterization of these lesions. Imaging findings such as location of a soft tissue mass in the region of a major nerve, nerve entering or exiting the mass, fusiform shape, abnormalities of the muscle supplied by the nerve, split-fat sign, target sign and fascicular appearance should always evoke a peripheric nerve sheath neoplasm. Although no single imaging finding or combination of findings allows definitive differentiation between benign from malign peripheric neurogenic tumors, both US and MR imaging may show useful features that can lead us to a correct diagnosis and improve patient treatment. Traumatic neuromas and Morton neuromas are commonly associated to an amputation stump or are located in the intermetatarsal space. Lipomatosis of a nerve usually appears as a nerve enlargement, with thickened nerve fascicles, embedded in evenly distributed fat. Nerve sheath ganglion has a cystic appearance and commonly occurs at the level of the knee. Intraneural perineuroma usually affects young people and manifests as a focal and fusiform nerve enlargement. In this article, we review clinical characteristics and radiologic appearances of these neurogenic lesions, observing pathologic correlation, when possible.

Abstract
PURPOSE To compare tomosynthesis with radiography for the detection of hand and wrist bone erosions in patients with rheumatoid arthritis (RA), using multidetector computed tomography (CT) as the reference method. MATERIALS AND METHODS The study was approved by the local ethics committee, and written consent was obtained from all patients. From December 2008 to April 2009, 30 consecutive patients with RA were included in this prospective study. They underwent radiography, tomosynthesis, and CT of the most symptomatic hand and wrist on the same day. Two radiologists and one rheumatologist independently read images from the three imaging modalities. RESULTS A total of 232 erosions were detected with CT, while 199 and 140 erosions, respectively, were detected with tomosynthesis and radiography. More erosions were revealed with CT than with tomosynthesis and radiography (P < .0001); significantly more erosions were shown with tomosynthesis than with radiography (P < .0001). With CT as the reference method for bone erosions, the overall sensitivity, specificity, and accuracy of tomosynthesis were, respectively, 77.6%, 89.9%, and 83.1%. The corresponding values for radiography were 53.9%, 92%, and 70.9%. The sensitivity of each reader increased by roughly 20% with use of tomosynthesis. CONCLUSION The depiction of bone erosions of the hands and wrists is significantly greater with tomosynthesis than with radiography.

Abstract
The retinacula of the ankle are distinct structures defined as regions of localized thickening of the crural fascia covering the deep structures of the distal portion of the leg, ankle, and foot. Their role is to maintain the approximation of the tendons to the underlying bone. The retinacula of the ankle and foot contain the extensor retinaculum, the peroneal retinaculum, and the flexor retinaculum. Knowledge of the normal anatomy and imaging appearance of these structures is essential for the depiction of their injuries. Even though they may provide an explanation for chronic and unexplained residual pain after an injury, they are frequently overlooked or misdiagnosed.
