Case ReportsUnexpected primary osseous lymphoma as the cause of lactic acidosis in a patient suffering from pancreatitis.
A 45-year-old man was admitted due to acute pancreatitis. A severe lactic acidosis was found. ⋯ The images showed widespread abnormal FDG activity in the bone marrows throughout the body, suggestive of hematologic malignancy, which was confirmed as primary osseous non-Hodgkin lymphoma following a histopathological examination of the bone marrow. Chemotherapy against lymphoma was initiated and status of the lactic acidosis was rapidly corrected.

Case ReportsHepatitis C-related primary effusion lymphoma of the pleura and peritoneum, imaged with F-18 FDG PET/CT.
Primary Effusion Lymphoma (PEL) is a rare form of Non-Hodgkin lymphoma that involves serous body cavities (pleural, pericardial, or peritoneal) with lymphomatous effusions in the absence of lymphadenopathy or organomegaly. Although it was seen mostly in HIV-positive patients, it has recently been reported in HIV-negative patients with chronic Hepatitis B or C infections. PEL is associated with human herpes virus type-8 infection, often presents with rapidly progressive effusions and generally has a poor prognosis. ⋯ An F-18 FDG PET/CT showed marked ascites and pleural effusions with increased F-18 FDG uptake in the pleura and peritoneum on the left side. Analysis of the cells in the peritoneal fluid revealed a human herpes virus 8-positive PEL of the peritoneum. As a result the patient was no longer considered a liver transplant candidate and died 2 weeks after the diagnosis.

Health information technology and the electronic medical record.
Health Information Technology and the Electronic Medical Record are becoming increasingly important in virtually all aspects of medicine. This includes computer-assisted decision support, the integration of all aspects of the health record, ability to access patient information no matter where a patient seeks care, cost control, and health care research and quality improvement. It also has ramifications for the education of health care professionals and general community members. This article briefly examines some of the most important aspects of this development.

Case ReportsMidline cyst of the prostate mimicking malignancy on FDG PET/CT.
A 58-years-old man underwent F-18 FDG PET/CT for health screening. F-18 FDG PET/CT revealed a focal, round, and 1.5 cm-sized hypermetabolic lesion at midline of the prostate. The lesion was suspected as a urinary activity or malignancy. ⋯ On the attenuation-uncorrected image, the prostatic lesion was still evident. The lesion was considered as a midline cyst of prostate, communicating with urethra. It is suggested that radioactive urine remained in midline cyst resulting in the focal hypermetabolic lesion.

Case ReportsF-18 FDG PET/CT in an adult case of group B streptococcal sacroiliitis.
An adult patient presented with acute severe pelvic and low-back pain. Evaluations with CT and MRI were negative/inconclusive. F-18 FDG PET/CT localized the site of pathology in right sacroiliac-joint by demonstrating hypermetabolic activities conformal with the joint's outline, signifying infectious/inflammatory sacroiliitis. ⋯ Antibiotic treatment was started within 24 hours from onset of symptoms, and there was almost immediate partial pain relief. GBS sacroiliitis is a rare form of septic sacroiliitis requiring prompt diagnosis and urgent treatment. This is the first report of F-18 FDG PET/CT for diagnosing GBS sacroiliitis in adults with no predisposing factors.
