ABSTRACT
Arteriovenous (AV) fistulas are irregular connections between arteries and veins, and thoracic AV fistulas are rarely identified in clinical practice. We report a case of a 56-year-old female with a history of esophageal adenocarcinoma treated with radiation and resection who presented to the hospital due to hemoptysis. She underwent bronchoscopy revealing a tracheobronchial fistula, and esophagogastroduodenoscopy revealing active arterial bleed. Subsequent angiography uncovered an AV fistula between her right T8 intercostal artery and pulmonary vein with a pseudoaneurysm. She underwent coiling of her T8 and T9 intercostal arteries with resolution of her symptoms.
ABSTRACT
We report on a 66-year-old male who presented for evaluation of rapidly expanding lesions on his lower extremities. He first noticed these lesions following a trip to Costa Rica, in which he was bitten by several unidentified bugs. He was initially treated empirically with antibiotics in the outpatient setting with no improvement of his symptoms. His lesions continued to expand and spread locally which prompted further workup with a biopsy of one of his lesions. He was ultimately found to have Leishmaniasis (Viannis) guyanensis confirmed by microscopy and polymerase chain reaction. He was treated with aggressive wound care and amphotericin B due to the risk of progressing to involve his mucosa.
