An Unusual and Rare Presentation of Diffuse Tophaceous Gout.

Gout is a chronic disease characterized by recurrent attacks on joints from monosodium urate crystal deposition causing inflammation and severe pain. Patients at increased risk of developing gout include those with obesity, high consumption of alcohol or high-purine foods, genetic causes, and medication side effects. Typically, there are three stages of disease progression: acute, inter-critical, and chronic. Monoarticular joint disease is common however polyarticular gouty arthritis can result after years of acute flares. The chronic nature of the disease forms tophi, which are generally painless solid urate crystal collections. We present an unusual case of a 33-year-old male whose initial presentation was severe tophaceous gout affecting multiple joints, including bilateral elbows, knees, as well as hand and foot joints. His presentation was unique in that the tophi were not firm as expected, but were erythematous, tender, and fluctuant resembling an abscess. Laboratory and imaging studies confirmed the diagnosis of tophaceous gout and the patient's symptoms improved after starting systemic steroid therapy and colchicine. A multidisciplinary effort involving the medicine team and infectious disease, podiatry, and rheumatology consultants was essential in reaching the diagnosis. This case highlights the importance of keeping a broad differential diagnosis in a patient with polyarticular lesions and considering gout even with an atypical presentation such as in our patient.

Incidental Finding of an Exceptionally Large Left Atrial Myxoma Presenting as an Acute Cardioembolic Stroke.

Left atrial myxomas are rare tumors that arise in the left atrium of the heart. As they become larger, they tend to grow into the atrial lumen and disrupt cardiac hemodynamics. Commonly reported symptoms include dyspnea, orthopnea, cough, peripheral edema, and fatigue. On physical examination, a characteristic "tumor plop" may be heard in some patients early in diastole. Left atrial myxomas may cause emboli to be released into the systemic circulation, which can lead to acute cardiovascular events, including strokes. We present the case of a 43-year-old female with sudden-onset slurred speech, left facial droop, and left-sided hemiplegia. CT angiography of the brain revealed a right middle cerebral artery infarct, and the patient underwent emergent mechanical thrombectomy. Upon workup for secondary causes of stroke, echocardiogram revealed an incidental 8 cm left atrial myxoma. After stabilization in the ICU, the patient was taken to surgery and the tumor was successfully removed. Over the course of admission, the patient's left-sided hemiplegia gradually improved, and she was eventually transferred to inpatient rehabilitation care. A multidisciplinary effort involving medicine teams, neurology, cardiology, cardiothoracic surgery, neuro-interventional radiology, pain management, and endocrinology was essential in reaching the diagnosis. This case highlights the importance of considering a primary cardiac tumor such as a left atrial myxoma in the differential diagnosis when evaluating for secondary causes of acute ischemic stroke.
