Background:
Pneumorrhachis (PR) describes the clinical finding of air within the spinal canal and rarely has been associated with spontaneous pneumomediastinum. There is little medical literature addressing the evaluation and management of these patients in the emergency department.
Case Report:
We present a series of patients with PR secondary to a spontaneous pneumomediastinum and briefly review the available literature on the topic to discuss reasonable management strategies for patients presenting with this rare finding. In both cases, the patients had excellent outcomes with expectant management despite the worrisome finding of air in the spinal canal. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians must be able to promptly recognize and appropriately assess even uncommon pathology. As with other rare conditions, there are no published guidelines for the ED management of PR, necessitating the use of case presentations to educate providers as to the complications and plan of care of this diagnosis.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
