Imaging findings
The patient, known to have sarcoidosis, demonstrated a unique constellation of coalescent granulomatous nodules forming a pseudo-atoll or reverse galaxy-like sign. Myocardial enhancement on MRI in a non-vascular distribution further suggested cardiac involvement of sarcoidosis.
Key takeaways
Sarcoidosis can manifest as coalescent nodular opacities that form patterns such as the reverse galaxy sign. Cardiac involvement is an important manifestation to consider in sarcoid patients, particularly those with arrhythmias or conduction disturbances.
