Vanishing lung syndrome (VLS) is a rare condition characterized by giant emphysematous bullae. It is frequently misdiagnosed as pneumothorax. We describe a case of a 30-year-old male who presented with shortness of breath, reduced effort tolerance, and pleuritic chest pain for three months. He was initially diagnosed with bilateral pneumothorax based on clinical examination and chest radiograph findings. However, further imaging with a high resolution computed tomography (HRCT) of the thorax confirmed bilateral giant emphysematous bullae. Our patient subsequently underwent video-assisted thoracoscopic surgery (VATS) and bullectomy. In this report, we discuss the clinical presentations, radiological features, and the management of VLS. We also highlight the differentiating features of VLS from a pneumothorax.

Arteriovenous fistula (AVF) is an abnormal direct communication between an artery and the venous drainage without a capillary component. Although renal AVF is rare, detecting the disease is important to assist in management and, thus, help reverse the sequelae of the disease such as hypertension and heart failure. The clinical presentation and radiological features are important parameters that can help in the diagnosis and decision of treatment. We would like to share our successful approach to a 52-year-old female with idiopathic high-flow left renal AVF with concomitant renal artery aneurysm using a single Amplatzer vascular plug in the limit of our setting.

Dural arteriovenous fistulas (DAVFs) are abnormal connections between branches of the intracranial arteries and dural veins or sinuses. Advancements in the technique of endovascular embolization has made it the treatment of choice for DAVFs. The goal of treatment is to completely occlude the fistula orifice while maintaining the normal cerebral venous drainage. Depending on the site of the DAVF, endovascular treatment has its own challenges to the performing physician. In this case report, we will discuss complex anterior cranial fossa DAVFs, treatment approaches, and complications of the treatment.

Subclavian steal syndrome (SSS) is a manifestation of vertebrobasilar artery insufficiency due to stenosis of the proximal subclavian artery. It is a common vascular disorder; however, most patients are asymptomatic, and the disorder is commonly found incidentally during imaging. Nevertheless, some patients may present with arm ischemia or signs and symptoms of vertebrobasilar insufficiency, such as vertigo, dizziness, diplopia, ataxia, dysarthria, and syncopal episodes. We present a case of a male patient who presented with sudden onset dizziness, syncopal episodes, and blood pressure discrepancy between his arms. Diagnosis was a challenge, and the patient underwent several investigations, including basic bloodwork, electrocardiography (ECG), echocardiography, brain computed tomography (CT), and coronary CT angiography (CTA). Narrowing in the proximal left subclavian artery was found during coronary CTA, which confirmed the diagnosis of SSS.
