Abstract Background Diagnosis of aortic graft infection is challenging, and delayed diagnosis is associated with poor prognosis. Positron emission tomography/computed tomography (PET/CT) has improved diagnostic accuracy. Case summary A patient with a history of congenital heart disease was admitted due to fever. He had a history of four cardiac surgeries, including the Bentall procedure for endocarditis. Blood cultures were negative. A semi-mobile mass was detected in the distal portion of the aortic tube graft in echocardiography. PET/CT scan was used to confirm tube graft infection and to support proceeding to cardiac surgery. Discussion Using multimodality imaging, including PET/CT scan in combination with echocardiography, can improve diagnostic accuracy for the detection of aortic tube graft infection, infection of prosthetic valves, or intra-cardiac devices, especially in high-risk surgical cases.

Cerebral palsy (CP) is one of the non-progressive neurological diseases caused by damage to the brain tissue at birth, which leads to physical, cognitive and perceptive symptoms. Even after lifelong medical and therapeutic management there are residual deficits which affect the quality of life of the patients and their families. We examined a maximally rehabilitated, 20 year old male suffering from CP and Mental Retardation (MR). He had diplegic gait and Intelligence Quotient (IQ) score of 44 with affected fine motor activities, balance, speech and higher functions. Positron Emission Tomography—Computer Tomography (PET-CT) scan identified frontal, temporal, parietal, occipital, left cerebellar lobes, amygdala, hippocampus, and parahippocampus as the affected areas. He was treated with cellular therapy of Autologous Bone Marrow Derived Mono-Nuclear Cells (MNCs) transplantation followed by multidisciplinary rehabilitation. Six months following therapy, PET-CT scan showed significant increase in metabolic activity in all four lobes, mesial temporal structures and left cerebellar hemisphere, also supported by clinical improvement in IQ, social behavior, speech, balance and daily functioning. These findings provide preliminary evidence to support the efficacy of cellular therapy for the treatment of CP with MR. PET-CT scan can also be viewed as an impressive tool to monitor the effects of cellular therapy.

AimTo assess the usefulness of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET/CT) and the predictive factors for the diagnosis of sarcoidosis in patients with uveitis who have normal thoracic tomography.MethodsWe retrospectively reviewed 67 consecutive patients with uveitis of unknown aetiology or a suspected sarcoidosis. All patients with normal thoracic tomography underwent an 18F-FDG PET/CT, which was blindly reinterpreted. We then assessed the proportion of positive 18F-FDG PET/CT and the impact on the final aetiology, using Abad’s criteria for the diagnosis of intraocular sarcoidosis.Results19 of the 67 patients (28.4%) had mediastinal hypermetabolic foci on their 18F-FDG PET/CT consistent with sarcoidosis. It identified a biopsy site in two cases, which were consistent with sarcoidosis. At the end of the study, six patients (10%) had a proven sarcoidosis, six patients (9%) were considered as having a presumed sarcoidosis and 18 patients (26.9%) as having indeterminate sarcoidosis. 18F-FDG PET/CT enabled the diagnosis of presumed sarcoidosis in these six patients. An older age at diagnosis (p=0.004) and the presence of synechiae (p=0.02) were significantly related to an abnormal 18F-FDG PET/CT, with a trend for an elevated ACE (p=0.0993). We established a nomogram to estimate the probability of having positive findings on the 18F-FDG PET/CT according to different predictive factors.Conclusion18F-FDG PET/CT enabled the diagnosis of intraocular sarcoidosis even in patients with a normal CT scan. Older age at diagnosis, presence of synechiae and elevated ACE are associated with positive findings on 18F-FDG PET/CT consistent with sarcoidosis.
