Clinical Spectrum of Mediastinal Cysts: Symptomatology and Diagnosis

In any case, local disruption of thymic tissue can induce the formation or growth of cysts. In the current series, they mainly encompassed thymic cysts of congenital origin, and we excluded the cystic masses of neoplastic origin such as cystic thymomas or degeneration after surgery. Of note, Suster and Rosai reported 18 cases of multiocular thymic cysts, in addition to uniocular cysts.

Clinical Spectrum of Mediastinal Cysts: Pleural cysts

In this sense, bronchogenic cysts and esophageal cysts (duplications) share a similar developmental background, namely foregut budding errors, rather than being separate disease entities., A distinction is made between bronchogenic and esophageal cysts when cartilage is present, which suggests the cyst is bronchogenic in origin. However, Nobuhara et al advocated naming both types as “foregut cysts” because of their common embryological origin, anatomic proximity and…

Clinical Spectrum of Mediastinal Cysts: Bronchogenic cysts

Bronchogenic cysts were more common than esophageal cysts. The prevalence of bronchogenic cysts was reported to be 1:42,00 and 1:68,000 of admissions to two hospitals; however, it is difficult to appreciate the prevalence of the cysts exactly, since some aged patients have lesions that remain forever silent. Bronchogenic and esophageal cysts originate from the ventral primitive foregut as an anomalous budding of the laryngotracheal groove…

Clinical Spectrum of Mediastinal Cysts: Discussion

Three patients with bronchogenic cysts were converted to standard thoracotomy because of severe adhesions around the cysts, particularly into the esophageal muscle layers. Three patients with pericardial cysts had a communication with the pericardial cavity, which were found during surgery, thoracoscopic fenestration was performed. One female patient with a thymic cyst had a concurrent neurogenic tumor in the posterior mediastinum; therefore, the thymic tumor was…

Clinical Spectrum of Mediastinal Cysts: Surgical Treatment

Overall, 38 patients (36.2%) with mediastinal cysts were symptomatic: 39.2% of bronchogenic/esophageal foregut cysts, 40% of thymic cysts, and 15.8% of pericardial/pleural cysts. These symptoms usually appeared in progressive fashion in most patients. Overall common symptoms were retrosternal chest pain (14.3%), followed by dyspnea (7.6%), cough (6.7%), fever (5.7%), and hoarseness (4.8%). Of particular interest, 4 of 30 patients with benign thymic cysts presented with…

Clinical Spectrum of Mediastinal Cysts: Symptoms

Small subcarinal or hilar bronchogenic cysts, and small thymic cysts were found as homogenous water density masses on chest CT. Barium swallow studies and/or esophagoscopy were performed mainly for patients for suspected esophageal and bronchogenic cysts. CT was performed in patients after 1980, which revealed round, well-circumscribed masses of water density or a little higher. In the early series when CT was not available, induced…

Clinical Spectrum of Mediastinal Cysts: Results

Between 1951 and 2000, 806 patients (451 male and 355 female) were referred to our institution for treatment of mediastinal tumors. There were 105 mediastinal cysts (50 male and 55 female patients), comprising 13.0% of total mediastinal tumors. There were 10 pediatric patients < 15 years of age and 95 adult patients (age range, 6 months to 74 years; average age, 37.3 years). The prevalence…

Clinical Spectrum of Mediastinal Cysts

Cysts of the mediastinum, which are benign masses, constitute a small but important diagnostic group, representing 12 to 18% of all primary mediastinal tumors; however, the individual physician has little chance to know the clinical characteristics and total disease entities because of their relative rarity.
