Thrombus (Red-OCT)

Intraluminal mass, often with a layered, lobulated or pedunculated appearance. Relatively echolucent or variable gray-scale with speckling or scintillation. Blood flow in microchannels may also be apparent within some thrombi(asterisk). No one feature is pathognomonic for thrombus and IVUS should be considered presumptive. The corresponding case is available in OCT (red thrombus).
