Evaluation of the Pericardium with CT and MR.

Czum JM, Silas AM, Althoen MC - ISRN Cardiol (2014)

Bottom Line: The pericardium plays an important role in optimizing cardiac motion and chamber pressures and serves as a barrier to pathology.In addition to pericardial anatomy and function, this review article covers a variety of pericardial conditions, with mention of potential pitfalls encountered during interpretation of diagnostic imaging.Normal and abnormal appearance of pericardium on CT and MR imaging is emphasized, including dynamic imaging correlates of pericardial pathophysiology.

ABSTRACT
The pericardium plays an important role in optimizing cardiac motion and chamber pressures and serves as a barrier to pathology. In addition to pericardial anatomy and function, this review article covers a variety of pericardial conditions, with mention of potential pitfalls encountered during interpretation of diagnostic imaging. Normal and abnormal appearance of pericardium on CT and MR imaging is emphasized, including dynamic imaging correlates of pericardial pathophysiology.

A 59-year-old diabetic male presents to the emergency department complaining of worsening dyspnea 5 weeks after sustaining a fractured sternum in a motor vehicle collision. Initial noncontrast CT (a) demonstrates a gas-containing collection at the site of the sternal fracture and a bone fragment projecting posteriorly (arrow). CECT ((b) sagittal and (c) axial) shows pericardial hyperenhancement and effusion. Mediastinal gas is present (arrowheads). Separate aspirations of the sternal collection and pericardial fluid both yielded pus which grew methicillin-sensitive Staph. aureus. Broad-spectrum antibiotic therapy was begun and a pericardial window was placed.

Broad-spectrum antibiotic therapy was begun and a pericardial window was placed.

Mentions: The most common pericardial infection is viral, but bacterial, fungal, and atypical infections may occur, particularly in the setting of penetrating trauma, the postpericardiotomy period, immunosuppression, and sepsis. Tuberculous and fungal organisms cause chronic infections in immunosuppressed patients, usually leading to constrictive disease [21]. The most common bacterial pathogens are Staphylococcus, Streptococcus, Haemophilus, Propionibacterium, and Mycoplasma (Figure 7) [31]. Anaerobes may involve the pericardium by fistulization from the GI tract.
