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.

Introduction. Inflammatory myopathies are a rare group of diseases characterized by proximal weakness. Incidence ranges from 7.98/million/year and prevalence at 14/100,000. The utility of [18F] fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) scan is increasing for the complementary diagnosis of myopathies. Case Report. An 84-year-old male was admitted with a history of difficulty rising from a chair and a fall. Laboratory results showed increased creatine kinase levels of more than 50 times the normal reference values. Electromyography (EMG) showed myopathic changes, and FDG-PET/CT scan showed increased FDG uptake in bilateral quadriceps. A biopsy was performed revealing lymphocytic predominant infiltrates and myonecrosis. Prednisone and intravenous immunoglobulin (IVIG) were administered with strength improvement. The patient was discharged for further follow-up. Discussion. FDG-PET/CT in inflammatory diseases has proven useful as muscle fibers have increased FDG uptake. In some cases, FDG-PET/CT is also useful in determining associated neoplastic diseases.

322 Background: The role of fusion positron emission tomography/computed tomography scans (PET/CT) in staging of patients with pancreatic neoplasms (PN) is poorly defined. Currently PET/CT is not recommended as part of staging workup in patients with potentially resectable PN. Methods: Using a comprehensive cancer PET registry we identified 107 patients with PN who were potentially resectable based on the initial preoperative staging CT scans and endoscopic ultrasound (EUS), from January 2006 - December 2010. Subsequently all these patients had PET/CT performed prior to surgery. Patients with borderline resectable or locally advanced disease were excluded from the analysis. Statistical analyses were performed included sensitivity, specificity, positive predictive value, and negative predictive value. Statistical analyses were performed with STATA IC (Stata Statistical Software, Release 10.0; Strata Corp., College Station, TX). Results: PET/CT altered management and prevented futile surgery in 6.5 % patients by identifying metastases not detected by other modalities. One patient was found to have metastasis to the supraclavicular lymph node, five had occult hepatic lesions and another had peri-esophageal lymph nodes. All sites were biopsied and metastases confirmed by pathology. The sensitivity and specificity of PET/CT scan in detecting metastatic disease in this patient population was 42.1% and 83.3% respectively. Our study indicated a positive predictive value of PET/CT to be 40% and negative predictive value 84.5%, with a false positive rate of 16.6%. Conclusions: PET/CT was instrumental in preventing futile laprotomy in 6.5 % patients. Larger studies utilizing PET/CT in the initial preoperative staging workup are warranted.

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.
