OBJECTIVE: Very few reports have previously described spondylodiscitis as a potential complication of endovascular aortic aneurysm repair (EVAR). We present to our knowledge the first case series of spondylodiscitis following EVAR based on our institution's experience over an 11-year period. Particular attention is paid to the key imaging features and challenges encountered when performing spinal imaging in this complex patient group. MATERIALS AND METHODS: Of 1,847 patients who underwent EVAR at our institution between January 2006 and January 2017, a total of 9 patients were identified with imaging features of spondylodiscitis (0...

BACKGROUND: Fusariosis is an opportunistic fungal infection that affects mostly leukemic and hematopoietic stem cell transplant patients. Locally invasive and disseminated infection may occur. Treatment is challenging, and besides evaluation of immune status, one also needs to take into account organ involvement to predict the duration and prognosis. OBJECTIVE: The aim of this study was to present the findings and clinical follow-up from a series of cases of Fusarium spp...

Primary bronchus-associated lymphoid tissue (BALT) lymphoma comprises 5% of non-Hodgkin's lymphoma (NHL) and usually has an indolent course. Synchronous primary lung cancers with BALT lymphoma are seldom seen in patients with adenocarcinoma of the lung. Synchronous squamous cell carcinoma (SCC) and BALT lymphoma is an extremely rare occurrence. We report an unusual case of stage 4 BALT lymphoma requiring treatment that revealed an underlying ipsilateral mass causing a diagnostic dilemma. An 84-year-old female with a history of systemic lupus erythematosus, deep vein thrombosis, and thrombotic microangiopathy presented to the hospital with cough and dyspnea on exertion...

This report describes an estrogen receptor-positive breast cancer patient, who relapsed at two and a half years after the completion of adjuvant chemotherapy while being on the aromatase inhibition. Based on the clinical evidence for potential sensitivity of the tumor to hormone ablation, everolimus was added to continuing exemestane treatment. Oral chemotherapy was administered at further disease progression, however, it lasted only for 10 days due to rapidly deteriorating condition of the patient. BRCA test was performed just before the failure of endocrine therapy and revealed a gross deletion within BRCA2 gene...

Non-small cell lung cancer (NSCLC) is a high risk cancer and is usually scanned by PET-CT for testing, predicting and then give the treatment methods. However, in the actual hospital system, at least 640 images must be generated for each patient through PET-CT scanning. Especially in developing countries, a huge number of patients in NSCLC are attended by doctors. Artificial system can predict and make decision rapidly. According to explore and research artificial medical system, the selection of artificial observations also can result in low work efficiency for doctors...

Primary bone marrow lymphoma (PBML) is hard to diagnose in children, due to the difficult identification of malignant cells in bone marrow. The first case, a 5-year-old boy, showed knee swelling with an intermittent fever. The second case, a 12-year-old girl, showed fever of unknown origin without lymphadenopathy or hepatosplenomegaly. In both cases, the diagnosis was not confirmed despite the repeated bone marrow aspirations. Finally, bone marrow aspiration and biopsy at the positive site by positron emission tomography (PET)-CT contributed to definitive diagnosis of PBML...

BACKGROUND: Prognosis in oesophageal cancer (OC) is poor. The 5-year overall survival (OS) rate is approximately 15%. Personalised medicine is hoped to increase the 5- and 10-year OS rates. Quantitative analysis of PET is gaining substantial interest in prognostic research but requires the accurate definition of the metabolic tumour volume. This study compares prognostic models developed in the same patient cohort using individual PET segmentation algorithms and assesses the impact on patient risk stratification...

Brucellosis is a common, worldwide zoonosis. Clinical presentation is protean and often goes unrecognized. Hepatic brucelloma is a rare local complication of chronic brucellosis. We report a case in which magnetic resonance imaging and positron emission tomography imaging prompted suspicion of a hepatic malignancy. Diagnosis was ultimately made by serology and polymerase chain reaction of resected liver tissue.

Vertebral hemangioma is a benign condition, but sometimes, it might represent as diagnostic dilemma especially in elderly patient mimicking serious pathology like metastasis. We report a case of a 66-year-old man with prostate cancer. 18F-sodium fluoride positron emission tomography-computed tomography (18 F-NaF PET-CT) demonstrates increased radiotracer uptake at body of D4 vertebra. Magnetic resonance imaging shows features of atypical hemangioma; however, metastasis cannot be ruled out. To rule out bone metastasis, gallium-68-prostate-specific membrane antigen PET-CT is performed which shows no abnormal lesion...
