    Notes: Summary Thirty-two patients with CT-documented primary brainstem haemorrhage were reviewed retrospectively to obtain a clearer overall clinical picture, especially of the severely disabled survivors. They were divided into 3 groups according to outcome: eleven cases (Group 1) died within 1 month following haemorrhage, 11 cases (Group 2) survived but became bedridden, necessitating full living support, and 10 cases (Group 3) showed minimal neurological deficits and resumed normal activities. Owing to CT and improved critical care, the survival rate was 66% for the whole series. Group 2 comprised 34% of all cases. These patients were mostly alert, quadruplegic, and communicated only with great difficulty. The most common initial symptoms and CT finding in each group were as follows;Group 1: unconsciousness, respiratory disturbance, negative light reflex, tachycardia, and haematoma 〉3.0 cm;Group 2: disturbance of consciousness, respiratory disturbance, positive light reflex, normal heart rate, and 2.0〉 haematoma 〈3.5 cm; andGroup 3: alertness or only slight disturbance of consciousness, normal respiration, positive light reflex, normal heart rate, haematoma 〈2.5 cm. Although there is an overlap among them, these findings will be useful to distinguish the three groups from each other. Patients with disturbance of consciousness, respiratory disturbance, positive light reflex, normal heart rate, and 2.0〉 haematoma 〈3.5 cm, have a chance to survive, but in severely disabled condition, if they were treated with vigorous intensive care in the acute stage.

    Notes: Summary The purpose of the present study was to describe the clinical course of patients with Grade-5 ruptured aneurysms (WFNS grading). Among 250 consecutive cases of ruptured aneurysms, 60 Grade-5 patients were reviewed retrospectively, consisting of 24 males and 36 females with an average age of 58 years. Thirty-two patients were directly transferred to our clinic, while the remaining 28 were referred from other clinics. Duration from rupture to arrival at our clinic was within 1 hour in 25 cases and within 2 hours in 43 cases. Systolic blood pressure on admission was 186 mmHg on average. Obvious misdiagnoses by primary physicians were made in 7 cases. Ventricular drainage and clipping/trapping of the aneurysms were performed in 7 and 25 cases, respectively. Forty-nine patients died and the remaining 11 survived. One made a good recovery, 1 was moderately disabled, 8 severely disabled, and 1 in a vegetative state. The prognosis for Grade-5 patients is well known as being extremely poor, which also was the case in our series. Early referral and early surgical intervention have not changed this poor prognosis. Possible improvement of the outcome of this group might be expected by 1) public health and primary physician education on aneurysmal subarachnoid haemorrhage, and 2) control of blood pressure during referral.

    Notes: Summary Spinal cord infarcts are rare. We report serial MRI studies of a patient with a clinically diagnosed spontaneous spinal cord infarct. The usefulness of gadolinium diethylenetriaminepentaacetic acid-dimeglumine (Gd-DTPA) enhancement is also discussed. Serial MRI with Gd-DTPA is useful to diagnose the spinal cord infarction.

    Notes: Abstract Our purpose was to investigate nonhaemorrhagic infarcts with a short T1 in the cerebellum and basal ganglia. We carried out repeat MRI on 12 patients with infarcts in the cerebellum or basal ganglia with a short T1. Cerebellar cortical lesions showed high signal on T1-weighted spin-echo images beginning at 2 weeks, which became prominent from 3 weeks to 2 months, and persisted for as long as 14 months after the ictus. The basal ganglia lesions demonstrated slightly high signal from a week after the ictus, which became more intense thereafter. Signal intensity began to fade gradually after 2 months. High signal could be seen at the periphery until 5 months, and then disappeared, while low or isointense signal, seen in the central portion from day 20, persisted thereafter.

    Notes: Abstract We studied the MRI characteristics of cortical laminar necrosis in ischaemic stroke. We reviewed 13 patients with cortical laminar high signal on T1-weighted images to analyse the chronological changes in signal intensity and contrast enhancement. High-density cortical lesions began to appear on T1-weighted images about 2 weeks after the ictus. At 1–2 months they were prominent. They began to fade from 3 months but could be seen up to 11 months. These cortical lesions showed isointensity or high intensity on T2-weighted images and did not show low intensity at any stage. Contrast enhancement of the laminar lesions was prominent at 1–2 months and became less apparent from 3 months, but could be seen up to 8 months.

    Notes: Abstract To examine the chronological changes characteristic of cortical laminar necrosis caused by brain infarction, 16 patients were repeatedly examined using T1-, T2-weighted spin-echo, T2*-weighted gradient echo, fluid attenuated inversion recovery (FLAIR) images, and contrast enhanced T1-weighted images at 1.0 or 1.5 T. High intensity cortical lesions were visible on the T1-weighted images from 2 weeks after ictus and became prominent at 1 to 3 months, then became less apparent, but occasionally remained at high intensity for 2 years. High intensity cortical lesions on FLAIR images became prominent from 1 month, and then became less prominent from 1 year, but occasionally remained at high intensity for 2 years. Subcortical lesions did not display high intensity on T1-weighted images at any stage. On FLAIR images, subcortical lesions initially showed slightly high intensity and then low intensity from 6 months due to encephalomalacia. Cortical lesions showed prominent contrast enhancement from 2 weeks to 3 months, but subcortical lesions were prominent from 2 weeks only up to 1 month. T2*-weighted images disclosed haemosiderin in 3 of 7 patients, but there was no correlation with cortical short T1 lesions. Cortical laminar necrosis showed characteristic chronological signal changes on T1-weighted images and FLAIR images. Cortical short T1 lesions were found not to be caused by haemorrhagic infarction.
