Hippocampal T2 hyperintensities on 7Tesla MRI

Hippocampal T2 hyperintensities on 7 Tesla MRI☆

Hippocampal focal T2 hyperintensities (HT2Hs), also referred to as hippocampal sulcal cavities, are a common finding on Magnetic Resonance (MR) images. There is uncertainty about their etiology and clinical significance. In this study we aimed to describe these HT2Hs in more detail using high resolution 7 Tesla MR imaging, addressing 1) the MR signal characteristics of HT2Hs, 2) their occurrenc...

Late progression of neurological symptoms and MRI T2 hyperintensities in Parry-Romberg syndrome.

We describe a case of a 50-year-old woman who developed drug-resistant status epilepticus with complex partial and secondary generalised seizures. She had suffered from Parry-Romberg syndrome (PRS) for more than 40 years. Right-sided progressive hemifacial atrophy (PHA) had begun at the age of 7 (figure 1A), followed by epilepsy at the age of 14 years. In the past 2–3 years before the latest ad...

Myocardial Edema on T2-Weighted MRI

Importance of Evaluation of Ischemia/ Reperfusion Injury by Magnetic Resonance Imaging Although the advances in revascularization therapy have drastically decreased the mortality after ST-segment–elevation myocardial infarction (STEMI), the number of patients who develop heart failure after the reperfusion therapy continues to increase. More than 30% of the patients who survive STEMI develop he...

Do white matter hyperintensities on MRI matter clinically?

Cerebellar T2 hyperintensities in a patient with tremor.

A 58-year-old man noticed mild hand tremor for 2 years. As the tremor increased, he was referred to brain CT and consequently to MRI showing cerebellar and cerebral hyperintense areas on T2weighted images (figure). Neurologic examination was normal except for mild postural and intentional tremor, more pronounced on the left hand. Because of the typical,1,2 though not specific,3 radiologic featu...
