Usefulness of 18F-FDG PET/CT for evaluating response of ocular adnexal lymphoma to treatment.

The purpose of this study was to investigate the efficacy of F-fluoro-deoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for evaluating the ocular adnexal lymphoma treatment responses.We retrospectively reviewed data for 9 histologically confirmed cases of malignant lymphoma. All patients had at least one ocular adnexal tumor site and underwent FDG PET/CT before and after treatment.

18F-FDG PET/CT imaging of atypical subacute thyroiditis in thyrotoxicosis: A case report.

Background: In addition to its established role in oncologic imaging, F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) is useful for the assessment of inflammatory activity. However, subacute thyroiditis (SAT) in thyrotoxicosis is rarely detected during these scans.

Case: A 66-year-old man with SAT in thyrotoxicosis demonstrated symptoms of transient fatigue, headache, and fever, without typical neck pain.

Residual FDG uptake of primary thyroid lymphoma after treatment may overestimate residual lymphoma.

Objective: To assess F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) images in primary thyroid lymphoma (PTL) patients before and after treatment.

Methods: We conducted a retrospective review of data for ten patients (four men, six women) of mean age 65 (range 48-88) years, with histopathologically confirmed malignant thyroid lymphoma who underwent pre-treatment and post-treatment F-FDG PET between January 2005 and December 2014. Thyroid uptake was assessed by the 5-point scale score based on maximum intensity projection images.

(18)F-FDG uptake of the spinal cord was decreased after conventional dose radiotherapy in esophageal cancer patients.

Objective: We retrospectively investigated changes of (18)F-fluorodeocyglucose ((18)F-FDG) uptake in the spinal cord, inside and outside the radiation fields, in patients with esophageal cancer before and after conventional dose radiotherapy.

Methods: A total of 17 consecutive patients with esophageal cancer (16 males, one female; age 50-83 years, mean 67.0 years), who underwent conventional dose radiotherapy and (18)F-FDG PET/CT before and 5.

A familial case of mitochondrial disease resembling Alport syndrome.

A 38-year-old man with mild sensorineural hearing loss, diabetes mellitus, proteinuria, and slight renal dysfunction was admitted to our hospital for a renal biopsy to determine the cause of kidney disease. His elder sister and mother also had sensorineural hearing loss and renal failure, suggesting the existence of a common genetic disease in this family. Although the clinical features of the patient were similar to features of Alport syndrome, renal biopsy revealed no sign of Alport syndrome.
