ABSTRACT

Extraskeletal osteosarcoma (ESOS) is a rare malignant mesenchymal soft tissue tumor that usually arises in the lower extremities. It is typically a high-grade malignancy that represents only around 1%-2% of all soft tissue sarcomas and 2%-4% of all osteosarcomas. In this report, we describe a case of a 67-year-old female who presented with a 4-day history of a painless lump in her posterior right thigh. Workup utilizing different imaging modalities yielded a diagnosis of ESOS. The radiologic features of ESOS, as well as the current treatment paradigm and prognosis of this rare malignancy, will be discussed based on a review of the literature.

ABSTRACT

PURPOSE: To estimate the rates of technical success and adverse events of vascular closure devices (VCDs) in the brachial artery and compare the rates of adverse events with manual compression. MATERIALS AND METHODS: MEDLINE and Embase were searched for observational studies examining VCDs in the brachial artery. Meta-analyses were performed using random effects for the following outcomes: (a) technical success, (b) hematoma at the access site, (c) pseudoaneurysm, (d) local neurological adverse events, and (e) total number of adverse events. A pairwise meta-analysis compared VCD with manual compression for the outcomes of hematoma and the total number of adverse events. RESULTS: Of 1,761 eligible records, 16 studies including 510 access sites were included. Primary procedures performed were peripheral arterial disease interventions, percutaneous coronary intervention, and endovascular thrombectomy for ischemic stroke. The technical success rate was 93% (95% CI, 87%-96%; I2 = 47%). Data on the following adverse events were obtained via meta-analysis: (a) hematoma, 9% (5%-15%; I2 = 54%); (b) stenosis or occlusion at access site, 3% (1%-14%; I2 = 51%); (c) infection, 0% (0%-5%; I2 = 0%); (d) pseudoaneurysm, 4% (1%-13%; I2 = 61%); (e) local neurological adverse events, 5% (2%-13%; I2 = 54%); and (f) total number of adverse events, 15% (10%-22%; I2 = 51%). Angio-Seal success rate was 96% (93%-98%; I2 = 0%), whereas the ExoSeal success rate was 93% (69%-99%; I2 = 61%). When comparing VCD and manual compression, there was no difference in hematoma formation (relative risk, 0.75; 95% CI, 0.35-1.63; I2 = 0%; P = .47) or the total number of adverse events (relative risk, 0.75; 95% CI, 0.35-1.58; I2 = 76%; P = .45). CONCLUSIONS: Despite being off-label, studies suggest that VCDs in the brachial artery have a high technical success rate. There was no significant difference in adverse events between VCDs and manual compression in the brachial artery.

ABSTRACT

In this report, we describe a case of a 43-year-old male who sustained a displaced mid chondral costal cartilage fracture along with multiple ipsilateral rib fractures following a jet ski collision. Costal cartilage fractures (CC) are commonly missed on imaging evaluation, and accordingly underreported in the literature. High-energy blunt chest trauma represents the most common mechanism for CC injuries. Computed Tomography (CT) is the modality of choice to diagnose CC fractures along with the associated cardiopulmonary and abdominal injuries in polytrauma patients. There is currently no consensus with respect to the management of CC fractures. Further research is required to explore the long-term impact of CC fractures on thoracic cage stability.

ABSTRACT

PURPOSE: The aim of this national survey was to assess the overall impact of the coronavirus disease 2019 (COVID-19) pandemic on the provision of interventional radiology (IR) services in Canada. METHODS: An anonymous electronic survey was distributed via national and regional radiology societies, exploring (1) center information and staffing, (2) acute and on-call IR services, (3) elective IR services, (4) IR clinics, (5) multidisciplinary rounds, (6) IR training, (7) personal protection equipment (PPE), and departmental logistics. RESULTS: Individual responses were received from 142 interventional radiologists across Canada (estimated 70% response rate). Nearly half of the participants (49.3%) reported an overall decrease in demand for acute IR services; on-call services were maintained at centers that routinely provide these services (99%). The majority of respondents (73.2%) were performing inpatient IR procedures at the bedside where possible. Most participants (88%) reported an overall decrease in elective IR services. Interventional radiology clinics and multidisciplinary rounds were predominately transitioned to virtual platforms. The vast majority of participants (93.7%) reported their center had disseminated an IR specific PPE policy; 73% reported a decrease in case volume for trainees by at least 25% and a proportion of trainees will either have a delay in starting their careers as IR attendings (24%) or fellowship training (35%). CONCLUSION: The COVID-19 pandemic has had a profound impact on IR services in Canada, particularly for elective cases. Many centers have utilized virtual platforms to provide multidisciplinary meetings, IR clinics, and training. Guidelines should be followed to ensure patient and staff safety while resuming IR services.

ABSTRACT

We describe a case of a benign breast cavernous hemangioma in a 77-year-old male patient, which is a rare entity with less than 20 cases published in the literature since 1936. The mammographic and sonographic features of breast hemangiomas are nonspecific and tissue sampling is necessary as the diagnosis of exclusion is male breast carcinoma. Core biopsy is a reliable diagnostic tool for breast hemangiomas. Differentiating between benign breast hemangiomas and angiosarcomas is of outmost importance to appropriate care management as the former can be treated conservatively with follow-up or surgical excision and the latter usually managed aggressively with mastectomy.

ABSTRACT

We describe an unexpected and unique case of phosphaturic mesenchymal tumor in a 38-year-old female presenting with a painful lump in the plantar hindfoot. Phosphaturic mesenchymal tumors are extremely rare, generally benign soft tissue or osseous tumors, which are associated with overexpression of fibroblast growth factor-23 and tumor-associated osteomalacia. Patients often present with progressive signs and symptoms including systemic bone pain, muscle weakness, and insufficiency fractures, and timely diagnosis is paramount to appropriate therapy. Tumor resection is almost always curative with normalization of laboratory markers and resolution of symptomatology.
