RESUMO
Dermatomyositis (DM) and polymyositis (PM) are both immune-mediated inflammatory myopathies known to occur in paraneoplastic syndromes associated with a new diagnosis of malignancy, most commonly breast, ovarian, lung, pancreatic, stomach, colorectal, and Non-Hodgkin's lymphoma1 in DM and breast, lung, bladder cancer, and Non-Hodgkin's lymphoma in PM. 2,3,4 While inflammatory markers such as creatine kinase (CK) may be elevated with either DM or PM, marked elevation is rare. Herein, we report a case of newly diagnosed pancreatic cancer presenting with inflammatory myopathy and marked CK elevation. We review the frequency of PM as a paraneoplastic syndrome, the association with marked CK elevation, and the association with pancreatic cancer.
RESUMO
INTRODUCTION: Aspergillus species are ubiquitous fungi that may cause invasive infection, particularly in immunocompromised patients. Invasive aspergillosis most commonly affects the lungs but can also disseminate to the central nervous system (CNS). Manifestations of CNS aspergillosis include abscesses and, rarely, mycotic aneurysm leading to subarachnoid hemorrhage (SAH). CASE PRESENTATION: A 48-year-old man undergoing treatment for squamous cell cancer of the larynx with chemotherapy and steroids presented with dysarthria and weakness. He was found to have both lung and CNS infection secondary to Aspergillus species. While receiving intravenous antifungal treatment after biopsy-proven Aspergillus infection, he developed a fatal SAH caused by a mycotic aneurysm. DISCUSSION: Intracranial mycotic aneurysms are uncommon. However, mycotic aneurysm leading to a fatal SAH is a well-documented sequela of CNS aspergillosis. Mortality rates for CNS aspergillosis are extremely high. CONCLUSION: In immunosuppressed patients with neutropenia or using chronic steroids who have concurrent pulmonary and CNS infection, there should be a low threshold to treat empirically for fungal infections prior to confirmation of diagnosis.
