Primary chest wall tumors

Clinical characteristics and prognosis of patients with incidentally discovered chest wall sarcoma compared with those of symptomatic patients

OBJECTIVE

Sarcomas of the bone and soft tissues are detected after the onset of pain, detectable mass and related symptoms in the absence of a standardized screening examination. However, primary chest wall sarcomas can be incidentally detected upon chest X-ray or computed tomography. Previous studies of incidental primary chest wall sarcomas lack prognosis and disease-specific clinical data. This study aimed to investigate the prognoses of patients with incidental chest wall sarcomas and compare them with those of symptomatic patients.

METHODS

This study included 18 patients diagnosed with primary chest wall sarcoma between 2010 and 2023. Patient information such as age, sex, tumour diameter, tumour location, symptoms, treatment, time to treatment initiation, pathological diagnosis and outcome were retrospectively analysed.

RESULTS

Among the 18 patients, the sarcomas were incidentally detected in five by chest X-ray and computed tomography in three and two patients, respectively. The pathological diagnoses of the patients were Ewing sarcoma, Chondrosarcoma grade 1, grade 2, periosteal osteosarcoma and malignant peripheral nerve sheath tumour. The patients had no symptoms at the first visit to our hospital, and no lesions in other organs were detected at the time of the initial examination. At the final follow-up, the patients remained disease-free after radical treatment. The tumour sizes of the five patients were significantly smaller than those of patients with symptoms (P = 0.003).

CONCLUSIONS

The incidental detection of chest wall sarcomas and consequent early detection and treatment of tumours improves patient prognosis relative to that of symptomatically diagnosed patients.

Outcomes following the excision of sarcoma and chest wall reconstruction using 3D printed implant

The survival outcomes of patients with chest wall sarcomas (CWS) were evaluated after receiving wide excision and chest wall reconstruction by using three-dimensional printed (3DP) implants. The survival outcomes evaluating the effect of 3DP implants for chest wall reconstruction is lacking. Here, forty-nine patients with CWS underwent radical wide excision and chest wall reconstruction using 3DP implants. The surgical data and long-term survival outcomes were collected and analyzed. With a median follow-up of 36 months, the disease-free survival (DFS) and overall survival (OS) were 31.7% and 58.5%, respectively. In addition, the 3-year DFS and OS can be significantly differentiated using the classification criteria of tumor grade, tumor size tumor area. Hence, wide excision and chest wall reconstruction using three-dimensional printed implants are a safe and effective treatment for chest wall sarcoma. The novel classification criteria of tumor size and area have the potential to predict the prognosis of CWS.

[Chest wall reconstruction with a non-rigid synthetic rib prosthesis: a multicenter study]

Chest wall resection is performed for a variety of diseases, for primary rib and soft tissue tumors, metastatic lesions, or locally invasive growth of lung and mediastinal tumors being the most common indications. Following the resection phase, it is essential to determine the method of chest wall reconstruction that will restore the structural function, preserve pulmonary biomechanics, reduce the likelihood of residual pleural space, pulmonary hernia, and protect intrathoracic organs. The main objective of this study is to investigate the outcomes of chest wall resection with reconstruction using Codubix material.

MATERIAL AND METHODS

This retrospective multicenter study included 22 patients who underwent chest wall tumor resection with subsequent Codubix rib endoprosthesis reconstruction from 2019 to 2023. Four medical institutions participated in the study: P.A. Herzen Moscow Cancer Research Institute, Sverdlovsk Regional Oncology Hospital, Morozov Children's City Clinical Hospital and Kaluga Regional Oncology Hospital. Inclusion criteria were the presence of chest wall tumors, both primary and secondary, removal of more than 2 ribs, resection of the rib arch and the sternum.

RESULTS

The median age was 60 years (48-66), 11 (50%) patients were females and 11 (50%) males. Operations for chest wall sarcoma, metastatic lesions, and lung cancer were performed in 9 (40.9%), 4 (18.2%), and 3 (13.6%) patients, respectively. The median number of removed ribs was 3 (2-4), with a maximum of 7. Sternotomy was performed in 9 (40.9%) patients, and subtotal resection of the body or handle of the sternum was carried out in 77.7%. Combined resections were performed in 14 (63.6%) patients. Radical tumor removal (R0) was achieved in 21 (95.5%) patients. Complications were observed in 9 (40.9%) patients, with intermuscular seroma being the most common in three (33.3%), followed by hydrothorax in 2 (22.2%), bilateral pneumonia, acute respiratory failure, and postoperative delirium in 1 (11.1%) patient each. One patient had the Codubix plate removed due to postoperative wound infection. The median overall and recurrence-free survival was not reached, and the 1-year recurrence-free survival was 63.9%, with an overall survival of 86.8%.

CONCLUSION

Reconstruction with Codubix material allows for satisfactory functional and cosmetic results, characterized by a low complication rate and good adaptive properties.

Collaborative Virtual Reality Real-Time 3D Image Editing for Chest Wall Resections and Reconstruction Planning

The integration of extended reality (XR) technologies into health care procedures presents transformative opportunities, particularly in surgical processes. This study delves into the utilization of virtual reality (VR) for preoperative planning related to chest wall resections in thoracic surgery. Leveraging the capabilities of 3-dimensional (3D) imaging, real-time visualization, and collaborative VR environments, surgeons gain enhanced anatomical insights and can develop predictive surgical strategies. Two clinical cases highlighted the effectiveness of this approach, showcasing the potential for personalized and intricate surgical planning. The setup provides an immersive, dynamic representation of real patient data, enabling collaboration among teams from separate locations. While VR offers enhanced interactive and visualization capabilities, preliminary evidence suggests it may support more refined preoperative strategies, potentially influence postoperative outcomes, and optimize resource management. However, its comparative advantage over traditional methods needs further empirical validation. Emphasizing the potential of XR, this exploration suggests its broad implications in thoracic surgery, especially when dealing with complex cases requiring multidisciplinary collaboration in the immersive virtual space, often referred to as the metaverse. This innovative approach necessitates further examination, marking a shift toward future surgical preparations. In this article, we sought to demonstrate the technique of an immersive real-time volume-rendered collaborative VR-planning tool using exemplary case studies in chest wall surgery.

The Role of Surgery in Primary Chest Wall Tumors: Over 20 Years’ Experience in Resection and Reconstruction

Background: Primary chest wall tumors comprise a heterogeneous group of neoplasms arising from soft tissues and bones. While surgical excision is the standard of care for benign tumors, the management of malignant tumors requires multimodal treatment. We conducted a predictive analysis of outcome, recurrence-free and overall survival. Methods: We retrospectively reviewed the clinical and pathological records of all patients treated in our center between 1998 and 2020. Results: 53 patients (15–85 years) were treated in our department. The average tumor diameter was 65 ± 35 mm (10–160 mm). Negative margins were obtained in 48 patients (90.6%), whereas in the remaining 5, R1 resection was accomplished. Median overall survival was 63,03 months (1–282 months). Overall survival was 90% at 1 year, 78% at 2 years, and 61% at 5 years. Our analysis identified tumor diameter, postoperative complications, and high grade of malignancy as factors that can influence prognosis. Conclusions: The treatment of primary chest wall tumors remains a very challenging process. Different histological types preclude definition of an unequivocal approach. Complete resection with healthy margins remains a definitive cornerstone in the treatment of these cancers as part of a more comprehensive approach.

Diagnostic value of 18F-FDG PET/CT in discriminating between benign and malignant lesions of the ribs

PURPOSE

Imaging biomarkers for rib mass are needed to optimize treatment plan. We investigated the diagnostic value of metabolic and volumetric parameters from 18F-fluorodeoxyglucose (FDG) positron-emission tomography/computed tomography (PET/CT) in discriminating between benign and malignant lesions of the ribs.

PATIENTS AND METHODS

Fifty-seven patients with pathologically proven diagnosis of rib lesions were retrospectively enrolled. The size of rib lesions, the maximum, mean, and peak standardized uptake value (SUVmax, SUVmean, SUVpeak), tumor-to-background ratio (TBR), metabolic tumor volume (MTV), and total lesions glycolysis (TLG) were measured. The FDG uptake patterns (segmental and discrete) and CT findings (soft tissue involvement and fracture) were also reviewed.

RESULTS

Among the multiple parameters extracted from PET/CT, the MTV of malignant lesions was significantly higher than that of benign lesions (median; 4.7 vs 0.2, respectively, P = .041). In receiver operating characteristics curve analysis, MTV had the largest area under curve of 0.672 for differentiating malignant from benign lesions. For identifying malignant lesions, an MTV threshold of 0.5 had a sensitivity of 85.0%, specificity of 47.1%, positive predictive value of 79.1%, negative predictive value of 57.1%, and accuracy of 73.7%. The presence of adjacent soft tissue involvement around rib lesions showed a significant association with malignancy (odds ratio = 6.750; 95% CI, 1.837-24.802, P = .003).

CONCLUSIONS

The MTV is a useful PET/CT parameter for assisting in the differential diagnosis of suspected malignant lesions of the ribs. CT finding of adjacent soft tissue involvement around rib was significantly associated with malignant lesions of the ribs.

Clavicular Malignancies: A Borderline Surgical Management

Nearly 1% of all bone cancers are primary clavicular tumors and because of their rarity, treating clinicians are unfamiliar with their diagnosis, classification, treatment options, and prognosis. In terms of preserving function and avoiding complications, clavicle reconstruction seems logical; however, further studies are needed to support this measure. Reconstruction techniques are difficult taking into account the anatomical structures surrounding the clavicle. When chest wall defects are present, a multidisciplinary team, including an orthopedist and thoracic and plastic surgeons, is of paramount importance for optimal surgical management. Malignant clavicle tumors may include primary and secondary malignancies and neighboring tumors with clavicular invasion. Surgical resection of complex thoracic tumors invading the clavicles can result in larger defects, requiring chest wall reconstruction, which is a substantial challenge for surgeons. Correct diagnosis with proper preoperative planning is essential for limiting complications. Post-resection reconstruction of the partial or total claviculectomy is important for several reasons, including maintaining the biomechanics of the scapular girdle, protecting the vessels and nerves, reducing pain, and maintaining the anatomical appearance of the shoulder. The chest wall resection and reconstruction techniques can involve either partial or full chest wall thickness, influencing the choice of reconstructive technique and materials. In the present paper, we aimed to synthesize the anatomical and physiopathological aspects and the small number of therapeutic surgical options that are currently available for these patients.

Expert consensus on resection of chest wall tumors and chest wall reconstruction

Chest wall tumors are a relatively uncommon disease in clinical practice. Most of the published studies about chest wall tumors are usually single-center retrospective studies, involving few patients. Therefore, evidences regarding clinical conclusions about chest wall tumors are lacking, and some controversial issues have still to be agreed upon. In January 2019, 73 experts in thoracic surgery, plastic surgery, science, and engineering jointly released the Chinese Expert Consensus on Chest Wall Tumor Resection and Chest Wall Reconstruction (2018 edition). After that, numerous experts put forward new perspectives on some academic issues in this version of the consensus, pointing out the necessity to further discuss the points of contention. Thus, we conducted a survey through the administration of a questionnaire among 85 experts in the world. Consensus has been reached on some major points as follows. (I) Wide excision should be performed for desmoid tumor (DT) of chest wall. After excluding the distant metastasis by multi-disciplinary team, solitary sternal plasmacytoma can be treated with extensive resection and adjuvant radiotherapy. (II) Wide excision with above 2 cm margin distance should be attempted to obtain R0 resection margin for chest wall tumor unless the tumor involves vital organs or structures, including the great vessels, heart, trachea, joints, and spine. (III) For patients with chest wall tumors undergoing unplanned excision (UE) for the first time, it is necessary to carry out wide excision as soon as possible within 1–3 months following the previous surgery. (IV) Current Tumor Node Metastasis staging criteria (American Joint Committee on Cancer) of bone tumor and soft tissue sarcoma are not suitable for chest wall sarcomas. (V) It is necessary to use rigid implants for chest wall reconstruction once the maximum diameter of the chest wall defect exceeds 5 cm in adults and adolescents. (VI) For non-small cell lung cancer (NSCLC) invading the chest wall, wide excision with neoadjuvant and/or adjuvant therapy are recommended for patients with stage T_3-4N_0-1M₀. As clear guidelines are lacking, these consensus statements on controversial issues on chest wall tumors and resection could possibly serve as further guidance in clinical practice during the upcoming years.

Benign rib tumors: a case series from tertiary care Centre of Nepal and review of literature

Rib tumors are rare. They can present with wide varieties of symptoms and differentiating benign from malignant lesions is challenging. A careful history and supporting investigations can help to reach the definite diagnosis. Surgical resection is the treatment of choice with excellent prognosis. A total of four patients were operated for the management of rib tumors over a period of 5 years at our institution. All four were benign lesions and included simple bone cyst, fibrous dysplasia with aneurysmal bone cyst, aneurysmal bone cyst and enchondroma. There were three male and one female. None of them is having recurrence till now. Surgical resection is the treatment of choice for benign rib tumors as it provides diagnostic and curative treatment.

[Surgical treatment of chest wall tumors]

The term chest wall tumor summarizes a heterogeneous group of malignant and benign tumors, whereby primary and secondary chest wall tumors are differentiated. The incidence of secondary chest wall tumors is higher than that of primary tumors. Primary chest wall tumors can arise from any anatomic structure of the chest wall. Surgical resection is usually the treatment of choice. Resection status and tumor differentiation are relevant prognostic factors. Treatment of secondary chest wall tumors is performed depending on the patient's symptoms and prognosis of the underlying disease. Lung carcinomas infiltrating the chest wall can be resected primarily or secondarily as part of multimodal therapeutic strategies. Anatomic lung resections combined with chest wall resection have a higher mortality than standard resections. Chest wall reconstruction after resection has the goal of reducing paradoxical respiratory motion, although not every chest wall defect requires reconstruction.

Surgical management of rare benign tumors of the sternum

Primary benign tumors of the sternum are an exceedingly rare entity. Surgical techniques regarding intervention for these lesions are not clearly defined in the literature given their scarcity. Operative techniques include en-bloc resection of the tumor, and this has proven to be successful in preventing local recurrence despite benign nature of the lesion. Given the often extensive defect created by the excision, reconstruction is frequently necessary; depending on the size of the defect, either autologous bone grafting or the use of synthetic materials may be indicated. This study serves to present two cases of rare primary benign tumors of the sternum, giant cell tumors and osteoma spongiosum and to summarize the available literature. We present a review of the literature of 17sternal giant cell tumor cases reported so far including our patient and unique case of osteoma spongiosum of the sternum, that discusses their surgical management, as well as reconstructive techniques that provided an excellent clinical result and a lack of recurrence on long term follow-up.

Three-dimensional custom-made carbon-fiber prosthesis for sternal reconstruction after sarcoma resection

Radical resection is the preferred therapy for primary malignant sternal tumors. Sternal reconstruction is required to guarantee the best preservation of respiratory mechanics, and adequate mediastinal protection and acceptable cosmetic results after extensive tumor resection. A wide variety of methods and materials have been described for sternal reconstruction. Titanium implants are preferred by many surgeons because of their optimal features. However, the smooth surface of the metal prostheses does not facilitate the inward growth of the tissue, and the high density of metal can block the X‐ray and cause adverse effects on postoperative imaging and radiotherapy. Therefore, in this article we present a case of sternal reconstruction by means of a three dimensional (3D) custom‐made carbon‐fiber prosthesis following extensive resection of a sternal synovial sarcoma. The microporous structure on the surface of the carbon fiber composite material facilitates the inward growth of the tissue. Low density (1.5 g/cm³) of carbon‐fiber implant will not block the X‐ray and eliminates the adverse effects caused by metal material of postoperative imaging and radiotherapy. The 3D custom‐made carbon‐fiber prosthesis matched the thoracic defect perfectly and the chest wall reconstruction was stable for more than 24 months.

Rib resection using a Gigli saw under thoracoscopic guidance

Introduction

Despite the advantages and expanded indications of video-assisted thoracoscopic surgery, the open surgical approach is commonly preferred for the surgical treatment of rib lesions. Such an approach could lead to disadvantageous results such as increased postoperative pain and prolonged hospital stay. Despite all these handicaps, thoracoscopic resection of isolated rib resection has been reported in a small number of publications.

Aim

To compare the clinical outcomes of patients with isolated benign rib pathologies treated with either minimally invasive or open surgery.

Material and methods

The medical records of 22 patients undergoing surgery for isolated benign rib pathologies between 2013 and 2017 were reviewed. Variables statistically compared between the two groups were age, gender, symptoms, lesion size, duration of the surgery, amount of intraoperative bleeding, conversion to open surgery, volume and duration of the drainage, postoperative complications, length of hospital stay, pathological diagnosis, follow-up period, recurrence, duration of narcotic analgesic usage and pain according to visual analog scale evaluation.

Results

The thoracoscopic approach was superior to conventional surgery in terms of drainage volume, time to drain removal, morbidity, hospital stay, narcotic analgesic treatment duration and postoperative pain scores. All thoracoscopic procedures were concluded successfully, and conversion to open surgery was not required. During the mean 14-month follow-up period, no recurrence was encountered in either group.

Conclusions

This technique is a safe option for isolated benign lesions of the ribs. It is more effective in patient recovery in the postoperative period and in the management of surgical pain.

Bifid sternum in a young woman: Multimodality imaging features

Bifid sternum is a rare fusion anomaly of the chest wall that accounts for 0.15% of all chest deformities and may be associated with cardiac or vascular anomalies. It is usually diagnosed and surgically corrected at birth or within the first month of life. Being a diagnosis made during the neonatal period, computed tomography scan and magnetic resonance imaging are not often performed; not so many cases in literature have been studied with II level diagnostic imaging, such as computed tomography or magnetic resonance.

We describe a case of bifid sternum, rarely diagnosed in adults, discovered in a 21-year-old woman who came to our Diagnostic Imaging Department to perform a chest magnetic resonance after a chest X-ray.

Reconstruction of the Thoracic Wall With Biologic Mesh After Resection for Chest Wall Tumors: A Presentation of a Case Series and Original Technique

INTRODUCTION

Synthetic materials have traditionally been used for tissue reconstruction in thoracic surgery. New biomaterials have been tested in other areas of surgery with good results. Non-cross-linked swine dermal collagen prosthesis has been used to reconstruct musculofascial defects in the trunk with low infection and herniation rate.

MATERIAL AND METHODS

Retrospectively, we analyze our initial experience of chest wall reconstruction on large defects using a non-cross-linked swine dermal collagen matrix mesh with a thickness of 1.4 mm. A total of 11 consecutive patients were included. Preoperative, intraoperative, and postoperative data were taken into consideration.

RESULTS

Eleven sarcoma patients with a mean age of 58.25 ± 12.9 years underwent chest wall resections. Complete thoracic wall defects ranged from 6 · 9 to 16 · 25 cm in size. In all cases, we used a porcine collagen matrix mesh, and in all patients, it was covered by transposition of myocutaneous flap. The complications occurred in 5 (45%) patients, 1 (9%) pneumonia, 1 atrial fibrillation (9%), and 3 (27%) wound healing difficulty because of hematoma or infection. There was no respiratory impairment, and the pulmonary function (total lung capacity, vital capacity, and forced expiratory volume in 1 second) was not statistically different before and after surgery. The 30-day mortality was 0%, 1-year mortality and 2-year mortality was 27.2%. The collagen material resulted in a durable and good to excellent chest wall stability in clinical follow-ups, and on computer tomography scans spanning over 2 years.

CONCLUSION

Non-cross-linked acellular porcine dermal collagen matrix is a feasible and reliable biological patch material for reconstruction of the thoracic wall. Excellent wound healing, long-term stability, low complication, and good pulmonary function are achieved even in large defects.

Metastatic Sarcomatoid Squamous Cell Carcinoma of the Cervix Presenting with Chest Mass

Background

Sarcomatoid squamous cell carcinoma is a rare and aggressive form of cervical cancer. We report a case of metastatic sarcomatoid squamous cell carcinoma (SSCC) of cervix that presented with an anterior chest wall mass.

Case

A 43-year-old Hispanic female presented with a two-month history of a central chest wall mass. The patient's only past medical history was SSCC of the cervix, stage IIB, diagnosed two years priorly. She underwent neoadjuvant chemoradiation therapy (CRT) with cisplatin followed by radical hysterectomy. Surgical margins were positive which led to adjuvant CRT with carboplatin and paclitaxel. PET scan 4 months after the postoperative treatment was negative for recurrence and metastatic disease. On current presentation, the CT chest revealed anterior mediastinal destructive soft tissue mass involving sternum, and the biopsy showed SSCC. The patient received palliative radiation therapy to her chest with improvement in pain and ability to swallow. After discussing the prognosis she refused further chemotherapy and decided on hospice care.

Conclusion

Despite good response to first-line therapy, SSCC tends to recur early and does not respond to second-line therapy. Radiation therapy seems to be the most effective modality for treatment, but randomized controlled trials of therapy are impractical.

Chest wall tumors: Diagnosis, treatment and reconstruction

The aim of the present study was to determine a suitable procedure for the treatment of chest wall neoplasms with less potential risk and an increased rate of survival. Fifty patients with suspected chest wall malignancies were analyzed using various preliminary investigation tools. Whole-chest scanning was performed in all the patients. The patients were subsequently subjected to biopsies for further confirmation of the neoplasm. All such patients were then treated with a surgical approach and radiation therapy, with a follow-up period lasting up to six years. The majority of the patients showed improved survival rates relative to conventional therapies. The survival rates of patients suffering from osteosarcoma (78%) were higher those of patients with rhabdomyosarcoma (73%) and malignant small round cell tumors (64%). The survival and the mortality rates of the patients with synovial sarcoma and fibrosarcoma were the same. This study, which was conducted on a small group of patients, has provided guidance for further studies on tumors of the chest wall, which may, in turn, increase the longevity of affected patients.

Surgical therapy of primary malignant bone tumours and soft tissue sarcomas of the chest wall: a two-institutional experience

PURPOSE

Primary malignant bone tumours and soft tissue sarcomas of the chest wall are exceedingly rare entities. The aim of this study was a retrospective two-institutional analysis of surgical therapy with respect to the kind and amount of the resection performed, the type of reconstruction and the oncological outcome.

METHODS

Between September 1999 and August 2010 31 patients (seven women and 24 men) were treated due to a primary malignant bone tumour or soft tissue sarcoma of the chest wall in two centres. Eight low-grade sarcomas were noted as well as 23 highly malignant sarcomas. The tumours originated from the sternum in six cases, from the ribs in 12 cases, from the soft tissues of the thoracic wall in 11 cases and from a vertebral body and the clavicle in one case each.

RESULTS

In 26 cases wide resection margins were achieved, while four were intralesional and one was marginal. In all 31 cases the defect of the chest wall was reconstructed using mesh grafts. At a mean follow-up of 51 months 20 patients were without evidence of disease, three were alive with disease, seven patients had died and one patient was lost to follow-up. One recurrence was detected after wide resection of a malignant triton tumour.

CONCLUSIONS

Primary malignant bone tumour or soft tissue sarcoma of the chest wall should be treated according to the same surgical oncological principles as established for the extremities. Reconstruction with mesh grafts and musculocutaneous flaps is associated with a low morbidity.

Rib tumors: a 15-year experience

OBJECTIVE

A retrospective study of rib tumors was conducted to review their clinical, radiological, and pathological features, the difficulties in differentiating benign from malignant tumors, as well as the early and long-term results of surgical management.

METHODS

All patients with rib lesions evaluated by the Thoracic Surgery Department from 1998 to 2012 were studied. The patient's age, sex, symptoms, radiologic evaluation, surgical procedure, pathologic diagnosis and follow-up were assessed.

RESULTS

Ninety-one patients (81 male, 10 female, age range 16-80) with rib tumors underwent surgery in a period of 15 years (1998-2012). 64 patients (70.33 %) had benign lesions and 27 patients (29.67 %) had malignant tumors. In the group with malignant tumors, the main symptom was pain, and in the group with benign tumors the main symptom was swelling. Ten patients with benign rib tumor and two with malignant tumor were detected during routine chest radiograph. All patients were treated surgically with wide excision of the tumor and the diagnosis was established histologically. In the benign cohort, osteochondromas, fibrous dysplasia, enchondroma, eosinophilic granuloma and posttraumatic fibro-osseous lesion/dysplasia were among the most customary diagnoses. In the malignant cohort, 13 patients (48.15 %) had metastatic lesions, with the remaining 14 patients having primary malignant rib tumor.

CONCLUSIONS

Although radiographic imaging has evolved, all rib lesions must be considered as potentially malignant until proven otherwise. Prompt intervention is necessary and surgery must consist of wide resection with tumor-free margins to provide the best chance for cure in both benign and malignant lesions.

Thoracic outlet syndrome caused by fibrous dysplasia of the first rib

Fibrous dysplasia causing thoracic outlet syndrome is rare. A 41-year-old woman presented with neurogenic thoracic outlet syndrome with imaging that demonstrated a large tumor of her proximal left first rib. Transaxillary excision was unsuccessful due to involvement of the subclavian vasculature and brachial plexus. Subsequent posterolateral thoracotomy and resection of her first rib revealed fibrous dysplasia. Thoracotomy should be considered in these cases for optimal vascular control and identification of thoracic outlet anatomy.
