“…The anterior and apical pericardium are clearly depicted on chest MRI, but is difficult to view the posterior pericardium. 10 In the present case, because T1-weighted short-axis images (Fig 4) showed a hyperintense zone that suggested epicardial fat between the left ventricle and the protruding LAA, whereas the T1-weighted coronal images did not, we made a diagnosis of congenital partial absence of the pericardium. However, even the anterior pericardium was not clearly visualized, emphasizing that it can be difficult to delineate the pericardium in patients with less visceral fat, such as children.…”

“…Thus, chest MRI is generally thought to be useful for the diagnosis of left atrial aneurysm and for the differential diagnosis of pericardial diseases. 4,10,11 In the present patient, plain chest radiographs revealed protrusion of the third arch, and transthoracic echocardiography, as well as chest CT, disclosed a mass, but no definite diagnosis was obtained. The mass was identified as protruding dilated LAA by transthoracic color Doppler echocardiography.…”

“…Therefore, accurate and consistent images are acquired and this modality is reported to be particularly effective for the diagnosis of left atrial aneurysm and for the detection of thrombi, 4,9 because it provides clear visualization of the structures around the atrium that are difficult to assess by transthoracic echocardiography. MRI has better soft tissue resolution than CT, so it can easily show the epicardial fat as a hyperintense zone on T1-weighted images, 10 and can also directly detect the pericardium within the fat layer. Thus, chest MRI is generally thought to be useful for the diagnosis of left atrial aneurysm and for the differential diagnosis of pericardial diseases.…”

“…The features on chest X-ray of absence of the left pericardium have been described as leftward displacement of the heart, prominent pulmonary artery and interposed lung tissue, causing a radiolucent zone between the main pulmonary artery and the aorta. [2][3][4][5]11,14 Similarly, echocardiographic features reflecting the leftward displacement of the heart, as in this case, have been described. [6][7][8] These features disappeared in the right lateral position because of the right-sided pericardial support.…”

“…2,3,5,9,10,15 MRI is useful for diagnosing absence of the pericardium because it more clearly delineates the anatomical relationships than the other modalities with its high soft tissue contrast and multiplanar capability. 5,9,11,14,15 The absence of pericardium itself can be definitively delineated with MRI which confirm the diagnosis of this entity. 14,15 In the present case, chest X-ray and echocardiographic features indicated a complete absence of the left pericardium and, based on the previous reports, did not suggest a partial absence of the left pericardium; however, MRI demonstrated the partial pericardium along the left atrial posterior wall and LV lateral wall, and taking all the imaging results into consideration, the patient was presumed to have partial absence of the left pericardium.…”

solated congenital absence of the pericardium is a rare malformation and can vary from partial to complete absence, occurring more often on the left than the right side. 1 The features of complete absence of the left pericardium on chest X-ray and echocardiography, which are mainly related to the displacement of the whole heart, have been described by many investigators. [2][3][4][5][6][7][8] In partial absence of the pericardium, the characteristic features are quite different from those of complete absence of the pericardium because partial absence is occasionally complicated with herniation of a cardiac structure. [9][10][11] We present a case of partial absence of the left pericardium that was diagnosed by delineating the pericardium with magnetic resonance imaging (MRI), although the chest X-ray and echocardiographic features indicated a complete absence. Case ReportA 44-year-old man was referred for the evaluation of atypical chest pain. The pain eased spontaneously after several minutes, but was triggered in the left lateral position and he felt no distress. His apical impulse was prominent and displaced leftward to the anterior axillary line in the fifth intercostal space and a grade I/VI systolic murmur was present in the pulmonary valve area. Electrocardiography revealed right-axis deviation (QRS axis: 106°) and Circulation Journal Vol.68, April 2004incomplete right-bundle branch block. The chest X-ray in the standing posteroanterior view demonstrated leftward displacement of the heart without tracheal deviation. The chest X-rays in the right and the left lateral positions showed unusual cardiac mobility in the leftward direction (Fig 1). In transthoracic echocardiography, the apical window was displaced laterally in the usual left lateral position. Each echocardiogram recorded at expiration is shown (Fig 2). The 2-dimensional echocardiogram in the Magnetic Resonance Imaging Differentiated Partial From Complete Absence of the Left Pericardium in a Case of Leftward Displacement of the HeartTetsuhiro Yamano, MD; Takahisa Sawada, MD; Kenzo Sakamoto, MD; Takeshi Nakamura, MD; Akihiro Azuma, MD; Masao Nakagawa, MDA 44-year-old man was referred to hospital for the evaluation of atypical chest pain. His chest X-ray showed leftward displacement of the heart. During echocardiography, the apical window displaced laterally in the usual left lateral position and characteristic motions of the interventricular septum and left ventricular posterior wall were recognized with postural alterations. We presumed a complete absence of the left pericardium. Magnetic resonance imaging (MRI), however, demonstrated a partial left-sided pericardium. The diagnosis was corrected to partial absence of the left pericardium and we have carefully followed up this case without surgical prophylactic intervention. It is very important to differentiate partial from complete absence of the pericardium, because only in patients with partial absence of the pericardium is there a risk of fatal myocardial strangulation. The features of the c...
