56 year old male with history of coronary artery disease. Axial CT through the heart shows apical curvilinear fat (yellow arrowheads, ( a and b) associated with apical myocardial dystrophic calcification (green arrowheads c and d) both indicating prior apical MI. In addition there mitral annular calcification (red arrowhead, b) and multifocal fatty deposits in the RV (white arrowheads, a and b) usually depicting age related degenerative changes,

Unusual cases
Pericardial Lipoma
CXR shows widening of the left main bronchus and a vague lucency at the apex of the heart, CT shows lipoma posterior to the LA
Lipoma at the SVC RA junction
This image of a coronally acquired T1 weighted MRI image of the heart shows a high intensity mass surrounding the SVC and the entrance right atrium (RA) with narrowing of the SVC. There were no symptoms of SVC syndrome in this patient with known COPD. Note that the mass has the intensity of subcutaneous fat. An atrial lipoma is the most likely diagnosis.

This series of axial T1 weighted MRI images of the heart show a high intensity mass surrounding the SVC (blue arrowhead) and the entrance to the right atrium (RA). There were no symptoms of SVC syndrome in this patient with known COPD. Note that the mass has the intensity of subcutaneous fat. An atrial lipoma is the most likely diagnosis.

FAT NECROSIS-Target shaped
79-year male with asymptomatic finding on axial CT of a focal sclerotic ring surround the epicardial fat on the right side of the heart (yellow arrowhead). This most likely reflects chronic epicardial fat necrosis

79-year male with asymptomatic finding on coronally reformatted CT of a focal sclerotic ring surround the epicardial fat on the right side of the heart (yellow arrowhead). This most likely reflects chronic epicardial fat necrosis

79-year male with asymptomatic finding on sagittally reformatted CT of a focal sclerotic ring surround the epicardial fat on the right side of the heart (yellow arrowhead). This most likely reflects chronic epicardial fat necrosis

Lipoma of the LV
37 year old male with no history of CAD with a fat containing nodule at the LV apex most likely representing a lipoma of the myocardium

AMYLOIDOSIS TRACHEA BRONCHI BRONCHIOLES
56-year-old female with stable tracheobronchial amyloidosis.
The CXR shows in the AP projection shows a small tubular density which on CT reflect as a small bronchus which is thickened and contains calcification. The lateral exam shows bronchial wall thickening
The CT shows multicentric thickening of the trachea and bronchi.
The bronchi to the left lower lobe and a middle lobe bronchus are thickened and contain calcium
There is nodular fat accumulation along the lateral wall and apex of the LV and within the RV. There is also linear fat accumulation in the mid septal region and prominent pericardial fat around the anterior wall of the RV
