A 32‐year‐old woman had a medical history of a hypoglycemic attack. One year later, she had a second hypoglycemic attack. She could move her limbs after an intravenous glucose injection, but communication difficulty and cerebellar ataxia remained. We found brain MRI abnormalities in the bilateral middle cerebellar peduncles and internal capsule. The patient was diagnosed with insulinoma. High‐intensity MRI fluid‐attenuated inversion recovery at the bilateral middle cerebellar peduncles remained on the 45th day, but it disappeared after 1.7 years from the second attack. Consciousness improved, but cerebellar ataxia remained. The patient was able to walk without a cane following rehabilitation. There are few case reports of MRI abnormalities in the bilateral middle cerebellar peduncles in hypoglycemic encephalopathy. This case showed that infratentorial lesions, such as those in the middle cerebellar peduncles, might be observed on MRI in hypoglycemic encephalopathy that MRI abnormalities might disappear at long‐term follow‐up.

We evaluated the accuracy of patient's body weight estimated by their relatives, focusing on differences in patients' and relatives' gender.Two hundred and thirty patients scheduled for elective surgery were included in this study. The correlation coefficients （r 2 ） and mean difference ±1.96 standard deviation between estimated and measured body weight were 0.81, -2.3±10.2 kg, 0.94, -0.3±5.5 kg, 0.81, -0.5±6.1 kg, and 0.87, -0.8±6.5 kg in male relatives -male patient, female relatives -male patient, male relatives -female patient, female relatives -female patient respectively.These data indicate that patient's weight estimated by their relatives was generally reliable. Body weights estimated by female relatives seem to be more accurate than those by male relatives.
