Lung herniation is an uncommon clinical entity characterized by protrusion of pulmonary tissue through an area of weakness in the chest wall. We present the case of a 56-year-old man with a history of chronic obstructive pulmonary disease (COPD) and crack-cocaine use who presented to the emergency department due to left-sided lateral chest pain, as well as a two-week history of cough, shortness of breath, and wheezing. Chest imaging revealed a contusion on the left flank and intercostal widening with a left-sided pulmonary herniation between ribs 8 and 9. Cardiothoracic surgery was consulted for assessment of pulmonary herniation and recommended conservative management. His pain was managed with multimodal analgesia and the patient was deemed stable for discharge. At outpatient follow-up two weeks later, his pain was well-controlled. To our knowledge, this is the first reported case of pulmonary herniation in which crack cocaine use is implicated as a contributing cause. The outcome achieved in our case supports the use of conservative management with analgesia as a valid strategy for select patients with lung herniation.

Crowned dens syndrome (CDS) is a clinical entity characterized by neck pain associated with fever, headaches, and neck stiffness, along with radiologic evidence of peri-odontoid process calcification in a characteristic "crown" or "halo" distribution. It is likely an underdiagnosed condition and patients can initially be misdiagnosed, leading to costly evaluation and unnecessary treatment interventions. We present the case of a 76-year-old man who presented to the emergency department (ED) with a 3-day history of progressively worsening neck pain that was associated with headaches, malaise, decreased oral intake, chills, and fever. Initial evaluation was significant for the presence of fever, tachycardia, and elevated inflammatory markers. We report a case of CDS attributed to calcium pyrophosphate deposition and review the pertinent literature about the presentation, diagnostic evaluation, and treatment of this rare clinical entity.
