Overview:
Mediastinal (chest) cysts and tumors are relatively common in infants and children, often necessitating removal, especially if symptomatic. The range of encountered cysts comprises bronchogenic, thymic, enterogenous, neurenteric, dermoid, cystic hygroma, and pericardial cysts, with surgical intervention often needed for those causing symptoms.
Symptoms may include:
Many mediastinal cysts in children are asymptomatic and discovered incidentally during imaging studies for unrelated reasons. However, if the cysts become large, they can cause symptoms by compressing adjacent structures such as:
- respiratory distress
- cough
- chest pain
- difficulty swallowing
- wheezing
- in some cases, infection of the cyst can lead to fever and additional symptoms depending on the cyst's location
Infections might present with redness, warmth, and tenderness, while congenital anomalies could be noticed as asymmetry or absence of breast tissue.
Treatment/procedure options:
The treatment approach for mediastinal cysts depends on the type of cyst, its size, the presence of symptoms, and any potential complications. Surgical removal is often recommended for symptomatic cysts, cysts that are at risk of causing complications, or when malignancy cannot be definitively excluded through imaging and diagnostic tests. The surgery aims to completely remove the cyst while minimizing the risk to surrounding structures in the mediastinum. The surgical approach can vary from open surgery (thoracotomy) to minimally invasive techniques (video-assisted thoracoscopic surgery, VATS), depending on the cyst's location, size, and the surgeon's expertise. Minimally invasive techniques are preferred when feasible, as they generally offer shorter recovery times, less pain, and smaller scars than open surgery. For asymptomatic cysts that are unlikely to cause complications, a conservative approach with regular monitoring may be chosen to observe for any changes in size or the development of symptoms that would warrant surgical intervention.
