Silent Strangulation: When a Neck Trauma Unveils a Hidden Danger

Mediastinitis is a severe inflammation of the mediastinum, the space in the chest that contains the heart, major blood vessels, trachea, and esophagus. It's life-threatening because the infection can quickly spread to vital organs. Infections can stem from esophageal perforations, complications from cardiothoracic surgery, or, as shown in this case, from infections spreading from adjacent tissues or a compromised airway. The rapid progression of mediastinitis can lead to septic shock, organ failure, and death if not promptly treated.

The initial symptoms were an earache, difficulty swallowing (dysphagia), and a sore throat, along with findings such as right tonsillar hypertrophy and a hyperemic right tympanum. The patient was initially diagnosed with tonsillitis. These symptoms, while common to less serious conditions, masked the underlying neck trauma that was the root cause of the subsequent mediastinitis. The subtle presentation of the injury, without a clear history of trauma, made the diagnosis challenging.

A manual strangulation attempt can fracture the thyroid cartilage. This fracture, even if seemingly minor, can compromise the airway and allow bacteria to enter the surrounding tissues. This breach in the body's defenses can lead to infection, which, if left untreated, can spread to the mediastinum, causing mediastinitis. The infection can then disseminate throughout the chest cavity. This cascade of events highlights the importance of recognizing that what appears to be a superficial injury can have profound and deadly consequences.

The initial diagnostic challenges included misleading symptoms, which pointed toward a common infection. The initial investigations, including blood work and a physical examination, did not immediately reveal the underlying neck trauma. Later, the patient's condition worsened with the appearance of new symptoms. The chest CT scan was crucial, revealing air in the posterior mediastinum and a fluid collection. An esophagogastroduodenoscopy was performed to rule out esophageal perforation, and it was followed by a chest tube insertion. A subsequent CT scan revealed a loculated fluid collection with thickened, hypervascularized edges. Despite these interventions, the patient's condition continued to deteriorate. The complete picture of the mediastinitis evolved gradually as the severity of the inflammation increased.

A thorough medical history is crucial because it can reveal a history of a trauma which may not be initially obvious, such as a manual strangulation attempt. Without this context, subtle symptoms like difficulty swallowing or neck pain might be misinterpreted. Overlooking these signs can lead to delayed diagnosis and treatment, as was the case here. This delay allows the infection to spread and worsen, potentially leading to life-threatening complications like mediastinitis, septic shock, and even death. A comprehensive history allows doctors to investigate the underlying cause of symptoms, potentially saving lives and ensuring that cases of foul play are properly addressed.
