Fourth branchial cleft anomalies are an exceptionally rare cause of recurrent neck mass in pediatric and adult patients. In this report, we present a case of an infected fourth branchial cleft cyst in a 20-year-old woman that presented with recurrent throat pain and deep neck abscesses. After undergoing repeated incision and drainage procedures, the patient underwent definitive management with direct laryngoscopy, ablation of the left pyriform sinus tract, left hemithyroidectomy, and excision of the branchial anomaly without evidence of recurrence. In addition to diagnosis and management, this case report highlights the unique anatomical relationship between fourth branchial anomalies and the pyriform fossa as well as the superior and recurrent laryngeal nerves.

Traumatic hip dislocations require prompt diagnosis and treatment to prevent avascular necrosis of the femoral head. This injury is further complicated when there is an ipsilateral femur fracture. Here, we present what is likely the first reported case of a patient with traumatic hip dislocation and ipsilateral femur fracture with transrectal displacement of the femoral head. The patient presented to a level one trauma center in 2006 as a transfer from another facility after being thrown from a pickup truck. Upon initial evaluation, a foreign body was palpated in the rectum. Computed tomography (CT) imaging showed that the right femoral head was lodged within the pelvis. In the operating room, an exploratory laparotomy was performed, and anoscopy confirmed the placement of the femoral head within the rectal lumen. The femoral head was extracted from the rectum transanally. The operation was abbreviated, as the patient became hemodynamically unstable, and he was taken to the intensive care unit. He returned to the operating room the following day for a repeat washout and proximal diversion. Despite numerous orthopedic procedures and operative washouts, he ultimately underwent a right hip disarticulation. Physicians should be aware that intracorporeal femoral head displacement is possible in select patients who have experienced a high-energy trauma mechanism. This is a complicated, highly morbid injury that poses various management challenges to orthopedic and acute care surgeons.
