We describe a patient who presented with an acute paresis of her distal right hand suggesting a peripheral median nerve lesion. However, on clinical examination a peripheral origin could not be verified, prompting further investigation. Diffusion-weighted magnetic resonance imaging revealed an acute ischaemic lesion in the hand knob area of the motor cortex. Isolated hand palsy in association with cerebral infarction has been reported occasionally. However, previously reported cases presented predominantly as ulnar or radial palsy. In this case report, we present a rather rare finding of an acute cerebral infarction mimicking median never palsy.

We are describing a case of a 14-year-old girl who developed acute cerebral infarction which was documented on diffusion-weighted magnetic resonance imaging (DWI). On detailed evaluation, diagnosis of cerebral proliferative angiopathy (CPA) was made. Incidentally, she had capillary malformation on the forehead contralateral to cerebral vascular malformation. To our knowledge, this is the first case of CPA in the literature where DWI abnormality was due to acute cerebral infarction.

This paper examines a case of extraskeletal chondroma in the hand of an 82-year-old female, first noticed about two years ago. Magnetic resonance imaging showed a mass in the carpal tunnel which extended from the wrist to the palm. The tumor was located between the thenar area and the hypothenar area at the palm level. There was no continuity to the carpal bone or radius bone. The entire size of the tumor was 120 mm × 45 mm × 42 mm. Although extraskeletal chondroma is sometimes seen, a large one in the hand is extremely rare. Since the tumor was too large to excise totally because median nerve entrapped it, it was divided into two parts and excised. After the operation, there was no neurological deficit or pain in the median nerve lesion.

Introduction: Due to improvements of catheter design and approach, catheterization-related cerebral infarctions are expected to decrease, whereas this may be counterbalanced by increased risk profile of patients who undergo catheterization. Aims: The aim of this study is to examine the prevalence and risk factors of symptomatic and asymptomatic catheterization-related cerebral infarctions in the contemporary era, using diffusion-weighted magnetic resonance imaging (MRI). Methods and Results: We retrospectively analyzed 84 patients who underwent 1237 diagnostic and interventional catheterization procedures conducted within 2010 and 2011 in our hospital and who obtained the MRI within 14 days after catheterization. Among these, 10 patients developed a neurological event underwent MRI for suspected cerebral infarction (group A), whereas 74 patients were asymptomatic and underwent MRI for various reasons (group B); 52% of patients for the assessment before coronary bypass or surgery of aortic valve, 19% for the systemic vascular assessment for atherosclerotic diseases, and 28% for other reasons. The MRI revealed a fresh cerebral infarction in 5 patients in group A and 22 patients (29.7%) in group B. In patients with infarct lesions, more number of catheters were used (p=0.01), the intravascular procedure was longer (mean ± SEM, 17.1 ± 1.7 minutes vs. 22.7 ± 2.4 minutes, p=0.06), and the mean age tended to be higher (mean ± SEM, 74.1 ± 1.67 vs. 70.4 ± 1.1, p=0.07). The features of infarction were as follows: 62.9% of patients had multiple lesions and relatively small lesions in asymptomatic patients compared to those in symptomatic patients. Conclusions: Symptomatic cerebral infarction occurred after 5 of 1237 (0.4%) procedures. However, the rate of asymptomatic catheterization-related cerebral infarctions detected using diffusion-weighted MRI remains high in high-risk patients or candidates for cardiac surgery, when the rate is compared to that reported by previous studies conducted around 10 years ago. More number of catheters used and longer procedure time were associated with cerebral infarction in present study and careful procedural planning is warranted.
