BACKGROUND Babesiosis is an emerging, tick-borne zoonosis caused by intraerythrocytic protozoa of the genus Babesia. Babesia microti is the main pathogen causing human disease and is endemic in the northeastern and upper midwestern parts of the USA. Severity of infection ranges from mild, self-limited, febrile viral-like illness accompanied by nonspecific symptoms to life-threatening infection complicated by severe hemolytic anemia, disseminated intravascular coagulation (DIC), acute respiratory distress syndrome (ARDS), and renal or/and hepatic failure.

Materials And Methods: Eleven healthy volunteers were imaged using TRICKS MR angiography at 3.
Objective: Although there is a well-recognized association between thymic hyperplasia and benign thyroid disorders, the prevalence of thymic hyperplasia in patients with malignant thyroid diseases has not been previously reported. We performed this study to determine the prevalence and morphologic features of thymic hyperplasia on CT scans of thyroid cancer patients.
Conclusions: Thymic hyperplasia is commonly observed on CT scans of thyroid cancer patients and almost always demonstrates a characteristic pyramidal configuration.
Objective: The mechanism by which nonarteritic anterior ischemic optic neuropathy (NAION) causes an infarct in the optic nerve is controversial. We studied the three-dimensional anatomic configuration of a NAION infarct to better elucidate its pathophysiology.
Design: Case report with clinicopathologic correlation.
