Posttraumatic pericardial cyst

Abstract

REsUMEnLos quistes pericárdicos son lesiones poco frecuentes que se presentan como hallazgo casual en estudios radiológicos realizados por otros motivos.La mayoría son asintomáticos (>50%) pero su localización y relación con estructuras vecinas determinan las manifestaciones clínicas (tos persistente, disnea, dolor torácico...) Presentamos el caso de un paciente con dolor torácico opresivo a las dos semanas de un traumatismo torácico con una imagen sospechosa en la placa de tórax.Palabras clave. Pericardio. Fibrilación auricular. Quiste. aBstRactPericardial cysts are uncommon lesions usually found incidentally upon the radiologic investigation of some other condition.

Current concepts of diagnosis and management of pericardial cysts

“…Inflammatory: Rheumatic pericarditis, Bacterial infection particularly tuberculosis, Echinococcosis6, 34, 35, 363. Traumatic 11 4. Post cardiac surgery6, 375.…”

“…Patients with pericardial cysts are mostly asymptomatic (50–75% cases) 5, 6, 7, 8, 9, 10, 11 and the diagnosis is usually an incidental finding in chest X-ray. Symptoms usually appear when the cyst compresses on a nearby structure, or undergoes complications39, 40, 41, 42 (vide Table 5) .…”

“…In 70% of the cases, these cysts are located in right cardiophrenic angle, in 22% cases in the left cardiophrenic angle and in 8% cases are located in the posterior or the anterior-superior part of the mediastinum 7 . Most of the cases (50–75%) are asymptomatic and are diagnosed incidentally during radiological investigations ordered as routine investigation for other causes of illness 6, 7, 8, 9, 10, 11. Symptoms may appear due to compression of the nearby structures, such as heart, great vessels, oesophagus and the tracheobronchial tree 11 .…”

Symptoms may appear due to compression of the nearby structures, such as heart, great vessels, oesophagus and the tracheobronchial tree 11 . Pericardial cysts are described in the medical literature under various terminologies like: le kyste pleuropericardique (Jeaubert de Beaujeu et al, 1945; Roche et al, 1954), pleural cyst, pericardial cyst, pericardial coelomic cyst (Lambert et al, 1940), springwater cyst (Greenfield et al, 1943), mesothelial cyst (Churchill and Mallory, 1937), and thin-walled cyst 12 …”

A Rare Case of Incidental Pericardial Cyst

“…In 70% of cases, the cyst is found in the right cardiophrenic angle, 22% in the left, and 8% in the posterior or anterosuperior part of the mediastinum. 3 These cysts are usually harmless unless; they become so big as to compress structures such as the heart oesophagus, great vessels, and tracheal tree; 4 or rupture into pericardial sac causing tamponade; 5 or can cause pericarditis by infection of the cyst; 6 or sudden cardiac death.…”
