Thoracic multidetector computed tomography-MDCT-was simultaneously performed during emergency abdominal CT in a patient presenting with abdominal pain and acute cardiogenic edema related to sick sinus syndrome and mitral prolapse with regurgitation. A constellation of severe but completely reversible interstitial and mediastinal features was found comprising pleural effusions, diffuse alveolar ground glass, thickening of the bronchial walls and septal lines, hazy infiltration of the mediastinal fat, and enlarged lymphatic nodes. Multiple atypical hypodense nodular "pearls" were also found. These oval shape or fusiform pearls were distributed along the thickened septal lines and disappeared completely after treatment. The hypothesis of transient lymphatic ectasia or lakes is proposed for these never previously described abnormalities.

We present two cases with late graft leakage of unknown aetiology after open total aortic arch repair (TAR). Case 1: a 73-year-old woman underwent TAR for arch aneurysm with 24-mm four-branch graft. She had a previous history of pacemaker implantation for sick sinus syndrome and warfarin therapy for atrial fibrillation. Follow-up computed tomography (CT) revealed increased low-density area around the graft 4 years after surgery and blood leakage was shown in delayed-phase CT. Thoracic endovascular aortic repair (TEVAR) was performed to cover the haematic leakage, and shrinkage of the lesion was achieved 1 month after TEVAR. Case 2: a 72-year-old man with diabetes mellitus, hypertension and hyperlipidaemia was admitted to our institute for treatment of aortic arch aneurysm. TAR was successfully performed; however, leakage from the prosthetic graft was noticed by expert radiologists in follow-up delayed-phase CT scan 6 years after surgery. The leakage was resolved 1 month after TEVAR. Although the cause of late leakage was not determined, the slowly expanding haematoma proved to be treatable by additional TEVAR.
