Coccidioidomycosis causes significant morbidity in endemic areas. In the absence of sensitive diagnostic serologic testing, clinicians have increasingly relied on lung and lymph node biopsies for diagnosis. Recently, endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) has been shown to be an excellent sampling method for the diagnosis and staging of lung cancers, especially when combined with endoscopic ultrasound guided fine needle aspiration (EUS-FNA). We present 13 consecutive cases where EBUS-TBNA and/or EUS-FNA of pulmonary lymph nodes were performed as part of the workup for pulmonary coccidioidomycosis. EBUS-TBNA+EUS-FNA led to diagnosis in all nine cases in which they were performed concurrently, and in the remaining 4 in which either was performed individually. BAL was performed in all cases with positive results in 5 (38%). The mean time to diagnose by EBUS/EUS (1.6 d) was significantly shorter than by bronchoalveolar lavage (6.3 d) (P=0.003). The findings indicate that combined EBUS-TBNA+EUS-FNA for lymph node biopsy facilitates early and accurate diagnosis of pulmonary coccidioidomycosis.
Spontaneous renal artery dissection is a rare cause of renal infarction and can be a diagnostic challenge at times, necessitating high index of suspicion. Other common underlying causes, especially thromboembolic phenomena, need to be considered and investigated first before making this uncommon diagnosis with vascular imaging studies. Very few cases did report strenuous exercise as a predisposing factor for the development of spontaneous renal artery dissection, but we believe that sexual intercourse has not been reported before as an underlying precipitating etiology. We report a case of a young male who presented with renal infarction that started during sexual intercourse and was found to have an angiographically proven renal artery dissection.
Bronchoscopy has garnered increased popularity in the biopsy of peripheral lung lesions. The development of navigational guided bronchoscopy systems along with radial endobronchial ultrasound (REBUS) allows clinicians to access and sample peripheral lesions. The development of robotic bronchoscopy improved localization of targets and diagnostic accuracy. Despite such technological advancements, published diagnostic yield remains lower compared to computer tomography (CT)-guided biopsy. The discordance between the real-time location of peripheral lesions and anticipated location from preplanned navigation software is often cited as the main variable impacting accurate biopsies. The utilization of cone beam CT (CBCT) with navigation-based bronchoscopy has been shown to assist with localizing targets in real-time and improving biopsy success. The resources, costs, and radiation associated with CBCT remains a hindrance in its wider adoption. Recently, digital tomosynthesis (DT) platforms have been developed as an alternative for real-time imaging guidance in peripheral lung lesions. In North America, there are several commercial platforms with distinct features and adaptation of DT. Early studies show the potential improvement in peripheral lesion sampling with DT. Despite the results of early observational studies, the true impact of DT-based imaging devices for peripheral lesion sampling cannot be determined without further prospective randomized trials and meta-analyses.
INTRODUCTION: Meigs' Syndrome has been described as the development of ovarian fibroma or fibroma-like mass with pleural effusion and ascitic fluid. It is present in approximately 1% of all ovarian fibroma, thecoma and granulosa cell tumors. Pseudo-Meigs' Syndrome is secondary to benign etiologies and reported to be more uncommon. These syndromes should be considered in women with the clinical triad of pleural effusion, ascites and a pelvic mass and can mimic more serious malignant tumors [1]. A thorough evaluation including biopsy and peritoneal and pleural fluid analyses need to be performed. CASE PRESENTATION:A G0P0 29-year-old female presents with chills and fatigue since the start of her menstrual cycle. She was found to be tachycardic, tachypneic and hypoxemic to 85% with moderate abdominal distention. CT of the chest, abdomen and pelvis showed a large left-sided pleural effusion, multiple abdominal masses with compressive effect and large-volume abdominal ascites. CA-125 level was elevated at 295 U/ml. Biopsy showed small muscle proliferation with bland spindle cells and no malignant features. Thoracentesis was consistent with exudative effusion and negative cytology. Left-sided pleural effusion continued to reaccumulate requiring multiple thoracenteses. Patient underwent left pleuroscopy with pleural biopsies showing fibrotic pleura and reactive mesothelial proliferation, negative for malignancy. There was an active ascitic fluid leak into the left hemithorax through a small, thinned-out region in the dome of the left hemidiaphragm. She underwent abdominal myomectomy several months later with resolution of symptoms. Final pathology was consistent with leiomyomata.DISCUSSION: We describe a case of abdominal leiomyomatosis resulting in ascites and leak into the left hemithorax with recurrent exudative pleural effusions and resolution after surgical myomectomy, consistent with Pseudo-Meigs' Syndrome [2]. Right-sided pleural effusions are most common as pleural fluid collects due to fluid leakage from edematous tumor resulting in translocation via diaphragmatic pores into the right hemidiaphragm [3]. Effusions are exudative in nature, although in previous studies only 1.6% of patients underwent pleural fluid analysis [4]. CA-125 are typically found to be elevated, with normalization post-surgery [5]. CA-125 levels were not re-checked post-myomectomy in our case. Surgical tumor removal results in resolution of ascites and pleural effusion [5]. Therefore, in patients presenting with pleural effusion and ascites in the setting of abdominal leiomyomata, Pseudo-Meigs' Syndrome should be suspected, and pleural fluid analysis and cytology play an important role in aiding diagnosis and further management. CONCLUSIONS:The prompt evaluation of patients with leiomyomatosis presenting with ascites and large pleural effusion can be vital in guiding future interventional management.
Background: Benign airway stenosis (BAS) represents a significant burden on patients, providers, and healthcare systems. Spray cryotherapy (SCT) has been proposed as an adjunctive treatment to reduce BAS recurrence. We sought to examine safety and practice variations of the latest SCT system when used for BAS.Methods: We conducted a retrospective multicenter cohort study in seven academic institutions within the Interventional Pulmonary Outcomes Group. All patients who underwent at least one SCT session with a diagnosis of BAS at the time of procedure at these institutions were included. Demographics, procedure characteristics, and adverse events were captured through each center's procedural database and electronic health record.Results: A total of 102 patients underwent 165 procedures involving SCT from 2013 to 2022. The most frequent etiology of BAS was iatrogenic (n = 36, 35%). In most cases, SCT was used prior to other standard BAS interventions (n = 125; 75%). The most frequent SCT actuation time per cycle was five seconds. Pneumothorax complicated four procedures, requiring tube thoracostomy in two. Significant post-SCT hypoxemia was noted in one case, with recovery by case conclusion and no long-term effects. There were no instances of air embolism, hemodynamic compromise, or procedural or in-hospital mortality.Conclusion: SCT as an adjunctive treatment for BAS was associated with a low rate of complications in this retrospective multicenter cohort study. SCT-related procedural aspects varied widely in examined cases, including actuation duration, number of actuations, and timing of actuations relative to other interventions.
