A 28 year-old Caucasian female, 3.5 months postpartum, presented to the TJUH ED with facial and neck swelling. She was in her usual state of health until approximately 1 month prior to admission when she noted the gradual onset of neck swelling. The neck swelling progressed to her face 4 days prior to admission; swelling in both areas was progressive and increasingly uncomfortable. Two months prior, the patient was treated for sinusitis with a course of antibiotics by an allergist; this treatment was unsuccessful, and she was referred her to an otolaryngologist, who performed a neck ultrasound and lab work. The patient reported that several enlarged lymph nodes were found in her neck. The patient was then sent for a CT of the neck and chest, which showed a mass in her mediastinum. She was planning to follow up with a cardiothoracic surgeon, however she developed symptomatic swelling and intermittent dysphagia.
