A Case Report: Malignancy Mimicking Mycotic Aneurysm

A 45 year old female with an acquired brain injury who presented to ED with recurrent falls, epigastric pain radiating to the left lower chest and constitutional symptoms was initially commenced on empirical antibiotic treatment for a suspected mycotic aneurysm. Laboratory testing revealed leukocytosis and computer tomography (CT) imaging showed an unusual paraaortic soft tissue mass further increasing the suspicion of mycotic aneurysm. However, due to the unusual appearance on CT and negative blood culture, an endobronchial ultrasound guided transoesophageal biopsy was performed to con irm the diagnosis. Histological indings were consistent with poorly differentiated adenocarcinoma and a diagnosis of malignancy secondary to possible cancer of the pancreas, biliary or gastrointestinal tract was made. The patient was subsequently palliated and passed away peacefully 27 days after admission.
