We previously observed spotty hyperintense lesions in the region of the perforating arteries on peri-ictal diffusion-weighted imaging (DWI); however, no report has formally described these findings. The aim of this study was to investigate focal intensities on peri-ictal DWI, and to evaluate the clinical significance of these lesions.Background/Aim: We conducted a retrospective review of 677 consecutive patients with seizure who completed peri-ictal DWI within 24 h after seizure onset. Patients were grouped according to the presence or absence of diffusion hyperintense lesions (DHLs) in the region of the perforating arteries. We compared clinical and imaging characteristics between these 2 groups.Methods: Among 677 patients, 23 patients (3.4%) had DHLs. Analyses of apparent diffusion coefficient values and fluid attenuated inversion recovery images suggested that DHLs were acute or subacute ischemic lesions that had appeared prior to seizure onset. Patients with DHLs were more likely to be older in age, have atrial fibrillation, and coronary artery disease, and have more severe deep white matter hyperintensity or leukoaraiosis compared to patients without DHLs.Results: DHLs detected on peri-ictal DWI may represent incidental acute cerebral microinfarcts in the aging brain, especially in patients with small vessel disease.

Since its introduction, MR imaging has been easy to perform on all children with lumbosacral cutaneous stigmata, and has enabled the phenomenal refinement of spinal pathology. We investigated the overall outcomes of children with spinal lipomas at the Osaka Medical Center and Research Institute for Maternal and Child Health in Osaka, Japan. Between 1991 and 2003, 76 children with a tethered cord underwent a total of 90 surgical procedures at our institutes. Of this cohort, 67 cases had spinal lipomas. The mean age of patients at first operation for asymptomatic lipoma was 22.4 months (range: 1 month to 16 years, trim mean: 10.1 months, mode: 5 months), except 4 cases. The mean total follow-up for the cohort since the first surgical procedure was 7.2 years (trim mean: 7.9 years). Since the introduction of MR imaging, the reoperation rate for symptoms or signs in our series was 16.4% (11 cases). Regarding the 13 subsequent reoperations (2 patients had 2 operations), 3 patients were reoperated on due to multiplication of the lipomas after untethering, 3 due to urologic symptoms and 5 due to orthopedic signs. There were 2 cases who also had to undergo reoperation early due to CSF leakage. Filum and conus lipomas have similar tethering pathologies, but differ in the outcome following surgery. Filum lipomas are benign, and therefore surgery is safe and effective. Conus lipomas are more difficult to manage. Copyright © 2005 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Ten children with a tethered cord and also an anorectal malformation are reported in this document. The anorectal malformations comprised 5 vesicointestinal fissures, 2 cloacal exstrophies, 2 rectovesical fistulas and 1 rectobulbar fistula. All of the patients underwent colostomy in advance of surgery for untethering of the spinal cord. Although their neurologic deficits had previously been considered static, they were subjected to radiographic examination of the caudal spine and found to have a tethered cord. These 10 children were among 55 children with a tethered cord surgically treated at the Division of Neurosurgery of the Osaka Medical Center and Research Institute for Maternal and Child Health during the last 11 years. Data were obtained for these 10 children (6 boys and 4 girls, mean age 1.7 years) who underwent surgical untethering. Several hypotheses are offered to explain this association. Anorectal malformations are related to underlying spinal cord anomalies, which may be amenable to neurosurgical correction. Eight of our patients had no skin stigma of the lumbosacral region, in contrast to an ordinary tethered cord. Spinal cord imaging is necessary to closely scrutinize these children.Copyright © 2003 S.

14. Transient Total Mesencephalic Locked-in Syndrome After Bilateral Ptosis Due To Basilar Artery Thrombosis.

- Abstract
Locked-in syndrome (LIS) usually occurs as a result of pontine lesions and has been classified into various categories on the basis of neurologic conditions, of which transient total mesencephalic LIS is extremely rare. A 53-year-old man presented with bilateral ptosis followed by a total locked-in state. In the clinical course, the patient successfully recovered with only left slight hemiparesis and skew deviation remaining. Magnetic resonance imaging revealed multiple ischemic lesions caused by thrombosis at the top of basilar artery, including the bilateral cerebral peduncles, tegmentum of the midbrain, and the right cerebellar hemisphere. Antecedent bilateral ptosis before the locked-in state may be related to ischemia in the central caudal nucleus of the oculomotor nuclei. We should pay attention to this easily missed condition during the treatment of ischemic stroke involving the basilar artery. [Copyright &y& Elsevier]

Background Atraumatic acute subdural hematoma (ASDH) associated with moyamoya disease (MMD) is rare, and only a few studies have reported the bleeding origin. We present a case of atraumatic ASDH attributable to a transdural anastomosis that developed owing to the compensatory mechanisms involved in the pathogenesis of advanced MMD. This is the first case of life-threatening atraumatic ASDH associated with MMD in which the rupture point was clearly visualized using a 3-dimensional rotational reconstructed image. Case Description A 37-year-old woman presented with sudden-onset, serious, atraumatic ASDH requiring emergency decompressive craniectomy. The cerebral angiograms revealed that she had advanced MMD with transdural anastomosis that was classified as Suzuki stage V with a 5-mm saccular aneurysm in the middle meningeal artery on the affected side, which was suggested as the bleeding origin. Follow-up angiograms demonstrated that the aneurysm spontaneously disappeared and was inferred to be a pseudoaneurysm. We performed a left extraintracranial bypass to prevent recurrent hemorrhage. With intensive rehabilitation, the patient accordingly achieved stroke-free survival with a modified Rankin Scale score of 3 for 1 year. Conclusions Atraumatic ASDH associated with MMD is a rare type of hemorrhagic MMD, and a 3-dimensional-rotational reconstructed image was useful to confirm the origin of the bleeding. The transdural anastomosis development most likely correlates with the occurrence of any type of hemorrhagic MMD. We should consider that the transdural anastomosis collapse can cause a life-threatening atraumatic ASDH and should plan a surgical strategy carefully so as not to destroy collateral supply through the transdural anastomosis in such cases. Highlights • Atraumatic acute subdural hematoma (ASDH) associated with moyamoya disease rarely occurs. • This is the first case of success in visualizing the bleeding point. • The development of TDA correlates with the occurrence of hemorrhagic moyamoya disease. • We should keep in mind that TDA collapse can cause a life-threatening atraumatic ASDH.
