Diagnosis With Brief Discussion
- Diagnosis
- All trans retinoic acid syndrome
- Radiologic Findings
- Chest PA shows engorged pulmonary artery in both lungs and bilateral pleural effusion is also seen.
HRCT shows airspace consolidation,ground-glass attenuation, and interlobular septal thickening in both lungs. Bilateral pleural effusion is accompanied. Pulmonary artery is engorged in both lungs.
- Brief Review
- ATRA is an effective therapy for acute promyelocytic leukemia(M3). ATRA can differentiate acute promyelocytic leukemia blasts into mature granulocytes reduce the risk of disseminated intravascular coagulation with few cytotoxic effects. ATRA is usually well tolerated, but major side effects can be observed, the ATRA syndrome being the most important of them.
ATRA syndrome occurs in up to 25% of the patients reated with ATRA. ATRA syndrome characterized by dypnea, unexplained fever, weight gain, fluid retention, multiple sites of hemorrhage, organ failure, and thrombotic events (1,2). Chest radiographic features of the ATRA syndrome include increased cardiothoracic ratio, increased vascular pedicle width, ground-glass opacity, peribronchial cuffing, septal lines, and pleural effusion (3). Some patients with ATRA syndrome have to receive mechanical ventilation because of severe hypoxemia (1, 4). However, once a diagnosis of ATRA syndrome has been made, a prompt recovery can be achieved by withdrawing ATRA and treating the patient with prednisolone (1, 5).
