Case History: 40-year-old male with fracture undergoes pre-anesthetic fitness evaluation for intra-medullary nailing at the fracture site.
Case History: 40-year-old male with fracture in distal end of tibia undergoes pre-anesthetic fitness evaluation for intra-medullary nailing at the fracture site.
Figure 1A and 1B. A sharply marginated homogenous oval-to-rounded opacity is noted in the right cardiophrenic angle. It is not silhouetting the cardiac or diaphragmatic borders. The lesion is making an obtuse angle within the lung parenchyma and vascular markings of the lung can be seen through the lesion â suggestive of a mediastinal lesion. No air fluid level or calcification seen. No evidence of riberosions. On the lateral radiograph of chest the lesion is noted in retrosternal space.
Figure 2. An anechoic cystic (c) lesion adjacent to the right side of the heart. It was seen superior to the liver. There were no septations or solid components within the lesion.
Figure 3. A fluid density structure is noted adjacent to the right side of the heart. The CT HU value of the lesion was between 2 and 10 HU. The ribs appeared normal. No other significant findings were noted.
Chest radiograph showed opacity in the right costophrenic angle. Diagnosis of benign pleuro-pericardial cyst.
Pericardial cysts result from failure of fusion of one of the mesenchymal lacunae that form the pericardial sac.
No studies have been performed to confirm the superiority of contrast CT over MRI or echocardiography for diagnosis and follow-up.
