Diagnosis particularities of lung cancer in a young patient without external risk factors – A case report

Lung cancer is the most common type of cancer worldwide, smoking being the strongest risk factor. We present the case of a non-smoker, a 23-year-old patient, without environmental exposure or personal pathological history, who was hospitalised for dry cough, a unique episode of haemoptysis and low-graded fever. He was admitted with a left basal diminished vesicular murmur, without detectable rales, and normal oxygen saturation. The chest X-ray highlighted left pleural effusion in a medium amount. A chest ultrasound revealed also an adjacent pulmonary consolidation. The cytological examination of the pleural fluid detected the presence of lymphocytes 36%, eosinophils 25%, polymorphonuclear 39% and frequent red blood cells. Angio-computer tomography confirmed the existence of a left hilar tumour formation with a mass effect on the hilar structures, possibly a few tumoral emboli in the lateral and posterior basal segmentary arteries, a lower left lobe consolidation, a left pleural effusion with hydroaeric level, and a left pneumothorax. The patient required a fibre bronchoscopy that showed us a proliferative infiltrative process, stenosis of the left lower bronchia, and extrinsic compression of the left lower lobe and the 6th segment. Infiltration of mucosa at the left basal pyramid was also detected. The histological examination argued for pulmonary adenocarcinoma. The particularities of the case consist of the lack of exposure to known risk factors for bronchopulmonary neoplasm and the early appearance of lung cancer and its complications in a young patient.

OVARIAN VEIN SYNDROME: A CASE REPORT

The ovarian Vein Syndrome was first reported in 1964, yet its existence as a true pathophysiological entity remains controversial. It may present as an acute ora chronic disease, typically affecting young, multiparous women. We present in this article a 32-year-old patient with chronic renal colic, ultrasound and CT urography showing an extrinsic compression of the right lumbar ureter by the ovarian vein, a ligation, anda resection of the ovarian vein were performed by transperitoneal laparoscopy.

A challenging pacemaker implantation in the presence of a giant right coronary aneurysm compressing the right atrium

Giant coronary artery aneurysm is an uncommon disease, treated with surgical intervention or percutaneous coil embolization. A thrombosed aneurysm can cause extrinsic compression on the cardiac chambers, with potential hemodynamic effects and may cause problems when we need to implant a cardiac device. We present a case of difficult pacemaker implantation in a patient with 3 syncopes, first-degree AV block and complete left bundle branch block on electrocardiogram. The patient presented a giant aneurysm of the right coronary artery (85 x 90 mm), thrombosed, with right atrial compression. The pacemaker implantation was hampered by the difficulty of passing the lead through the compressed right atrium; indeed, only with simultaneous echocardiographic and fluoroscopic guidance, was it possible to complete the procedure. This case demonstrates the utility of echocardiogram, in particular settings, in cardiac stimulation procedures.

Case Report: Extrinsic Compression of the Left Main Coronary Artery by a Giant Sinus of Valsalva Aneurysm

Sinus of Valsalva aneurysm (SoVA) is an uncommon clinical entity, which is present in roughly 0. 09% of the general population. The cause can either be acquired or congenital. Clinically the SoVA of unruptured status are rarely captured or even diagnosed due to atypical clinical presentations. Here, we present a rare case of exertional angina pectoris and recurrent syncope due to an extrinsically compressed left coronary artery by a giant SoVA in a 50-year-old female patient. This SoVA was successfully repaired by the surgical exclusion and the patient was still doing well after 2 years of follow-up.

Incoercible Vomiting in a Polycystic (ADPKD) Patient on Peritoneal Dialysis

Although gastrointestinal symptoms are not uncommon in PD patients due to several causes, such as infusion volume with early satiety, constipation, or peritonitis, sometimes the differential diagnosis is more challenging for nephrologists. We present the case of a woman with end-stage renal disease due to autosomal dominant polycystic kidney disease on PD who presented with swollen legs and incoercible vomiting. After ruling out constipation and infection, an abdominal CT was done, revealing extrinsic compression of the intrahepatic inferior cava vein (ICV) and massive venous thrombosis from ICV to bilateral iliofemoral deep veins. In addition, CT also showed displacement and extrinsic compression of the stomach, pylorus, and duodenum due to an enlarged liver cyst. Percutaneous drainage and sclerosis of the cyst compressing the stomach was performed, anticoagulation was started, and the patient clinically improved with complete resolution of symptoms.

Duodenal and Biliary Obstruction due to Extrinsic CompressionDuodenal and Biliary Obstruction due to Extrinsic Compression by Recurrent Lobular Breast Carcinoma: A Case Report

Metastases to the gastrointestinal tract (GIT) from breast carcinoma are rare, detected in approximately <5% of all breast cancer patients. Invasive lobular carcinoma (ILC) is the most common histological type of breast cancer to metastasize to the GIT. We report a case of abdominal recurrence of ILC of the breast causing intra-abdominal contracture leading to extrinsic compression of the duodenum and periampullary biliary tree. Four years after the patient’s diagnosis of a left breast pT1c, pN2, cM0 invasive lobular breast cancer, she presented with liver function tests consistent with biliary obstruction, and there was concern for a periampullary malignancy. Definitive diagnosis was achieved at laparotomy. This case demonstrates the importance of considering metastatic breast cancer as a potential cause of GI symptoms and radiological abnormalities affecting any part of the GIT of women with a previous history of lobular breast cancer. This case also highlights the effectiveness of chemotherapy in improving the survival and quality of life of these patients. Early recognition of this scenario enables prompt initiation of systemic therapy and avoids unnecessary surgical treatment. Despite the rarity, such patients will be encountered in clinical practice given the high prevalence of breast cancer. Moreover, the fact that the presenting symptoms of GI metastasis from breast cancer are usually not specific to the origin and mimic a primary intestinal disorder, health-care professionals beyond oncologists, especially gastroenterologists and primary care physicians, should be aware of this entity.

Patency period of a metallic ureteral stent and its determinants in patients with malignant ureteral obstruction: a prospective review

Background Malignant ureteral obstruction caused by extrinsic compression of a primary malignant tumour or by metastatic disease is an indicator of poor prognosis with a median life expectancy of about one year. We examined clinical outcomes following Resonance Metallic Ureteral Stent (Cook Medical, Bloomington, IN) placement in patients with malignant ureteral obstruction. Methods This was a prospective study of patients with malignant ureteral obstruction who underwent Resonance Metallic Ureteral Stent placement from April 2016 to March 2021. We registered 21 patients (27 collecting systems) with malignant ureteral obstruction and observed them prospectively. The patients first underwent polymer ureteral stent placement followed by replacement with a metallic ureteral stent one month later. Primary outcome was the metallic ureteral stent patency period based on both serum creatinine and the level of hydronephrosis; secondary outcomes were factors affecting patency period and stent-related complications such as symptoms of obstruction (flank pain), bladder irritation, haematuria, and urinary tract infection (presence or absence of fever). Results The study comprised 21 patients (six men, 15 women) with a mean age of 72 years. The median stent patency period in days was not available (NA) (95% CI 210–NA) due to the inability to extract this value from the Kaplan–Meier curve because the event rate did not reach 50%, and the one-year patency rate was 59.2% (95% CI 23.2–82.9). A normal serum creatinine (0.65 to 1.07 mg/dL for men and 0.46 to 0.79 mg/dL for women) one week after polymer ureteral stent placement was a significant factor affecting the long-term metallic ureteral stent patency period. There were no major complications. Conclusion The Resonance Metallic Ureteral Stent was effective and safe for patients with malignant ureteral obstruction. A normal serum creatinine level one week after placement of a polymer ureteral stent may predict a longer patency period of metallic ureteral stents in patients with malignant ureteral obstruction.

A case report: cardiac dysphagia — a ghost of the past?

Background Rheumatic heart disease has become rare in developed countries and physicians have grown unfamiliar with the disease and its clinical course. The mitral valve is most commonly affected leading to mitral regurgitation and/or stenosis. The chronic volume and/or pressure overload leads to atrial remodelling and enlargement, driving the development of atrial fibrillation and thromboembolic events. Case Summary A 87-year-old patient with a history of rheumatic mitral stenosis and mitral valve replacement was admitted to the neurology department for vertigo. A stroke was suspected and she underwent a transoesophageal echocardiogram which was complicated by dysphagia. Oesophageal manometry and CT revealed oesophagogastric junction outflow obstruction due to extrinsic compression by a giant left atrium. Discussion Dysphagia due to a giant left atrium is rare. Various diagnostic criteria exist and the prevalence thus depends on which criterium is used. It is mostly encountered in rheumatic mitral disease, although there are reports of non-rheumatic etiology. When the left atrium assumes giant proportions it can compress adjacent intrathoracic structures. Compression of the oesophagus can lead to dysphagia, as in our case. A transoesophageal echocardiogram in these cases is relatively contraindicated and should only be performed if there is considerable reason to believe that it may change patient management.

Treatment of Malignant Bile Duct Obstruction: What the Interventional Radiologist Needs to Know

Management of malignant bile duct obstruction is both a clinically important and technically challenging aspect of caring for patients with advanced malignancy. Bile duct obstruction can be caused by extrinsic compression, intrinsic tumor/stone/debris, or by biliary ischemia, inflammation, and sclerosis. Common indications for biliary intervention include lowering the serum bilirubin level for chemotherapy, ameliorating pruritus, treating cholangitis or bile leak, and providing access for bile duct biopsy or other adjuvant therapies. In some institutions, biliary drainage may also be considered prior to hepatic or pancreatic resection. Prior to undertaking biliary intervention, it is essential to have high-quality cross-sectional imaging to determine the level of obstruction, the presence of filling defects or atrophy, and status of the portal vein. High bile duct obstruction, which we consider to be obstruction above, at, or just below the confluence (Bismuth classifications IV, III, II, and some I), is optimally managed percutaneously rather than endoscopically because interventional radiologists can target specific ducts for drainage and can typically avoid introducing enteric contents into isolated undrained bile ducts. Options for biliary drainage include external or internal/external catheters and stents. In the setting of high obstruction, placement of a catheter or stent above the ampulla, preserving the function of the sphincter of Oddi, may lower the risk of future cholangitis by preventing enteric contamination of the biliary tree. Placement of a primary suprapapillary stent without a catheter, when possible, is the procedure most likely to keep the biliary tree sterile.

Hybrid, Endovascular, or Open Approach -- the Paget Schroetter Syndrome Dilemma

Background Paget-Schroetter Syndrome (PSS) is an uncommon disorder involving thrombosis of the subclavian vein, often caused by repetitive overuse or compression by the surrounding anatomical structures. Optimal management of PSS is a subject of debate, but current trends suggest that a hybrid approach employing endovascular intervention and open decompression may yield the best clinical results. This original article examines the roles played by endovascular thrombolysis, surgical decompression, and postoperative secondary intervention in the management of PSS. Methods Current literature on the management of PSS was reviewed and evaluated to ascertain what strategy of intervention would be optimal. In addition, clinical data from the University Hospital of Wales on the clinical outcomes in PSS patients undergoing different surgical approaches for anatomical decompression are included. Results Evaluation of data from the included series and available literature seems to indicate that endovascular thrombolytic devices such as the AngioJet or mechanical thrombectomy offer superior results than traditional catheter-directed thrombolysis. In addition, adjunctive procedures such as superior vena cava filters and venous angioplasty or bypass may augment maintenance of the subclavian vein lumen. Nonetheless, the subclavian vein must still be relieved of pressure from surrounding structures for treatment to be successful. Conclusions A hybrid approach to the management of PSS, encompassing endovascular and surgical interventions could possibly offer optimal clinical outcomes as both intrinsic lesions and extrinsic compression of the subclavian vein are resolved. This article recommends prospective research to determine the ideal endovascular treatment, and best surgical approach for decompression.
