Far-out syndrome (FOS) is caused by L5 nerve root entrapment at the L5-S1 extraforaminal area surrounded by the sacral alar and the transverse process. Here, we report a case with right L5 radiculopathy caused by L4-5 lumbar canal stenosis (LCS) and FOS. A 57-year-old man suffered from progressing right sciatica and leg pain in the L5 nerve root distribution. ⋯ Visual analogue scales of pain and numbness were 8.7 and 8.7 respectively at first examination. These scores decreased to 5.5 and 3.7 two months after the first operation for LCS, and to 0 and 0 one month after the second operation for FOS. We recommend that more attention be paid to FOS when patients with L5 radiculopathy are diagnosed.

Hypoglycemic hemiparesis is rare and can be misdiagnosed as cerebral infarction or transient ischemic attack. Early diagnosis of these two disorders is critical because, if not treated with prompt glucose administration, hypoglycemia may lead to a fatal clinical course. We reported two cases of hypoglycemic hemiparesis with a reversible splenial lesion on MRI. ⋯ We emphasize that checking plasma glucose level is necessary even in cases with hemiparesis. Furthermore, we should be aware that not every hyperintensity lesion on DWI is due to ischemia. There are times when it could be due to hypoglycemia.

Case Reports
[Retrieval of migrated microcatheter with retrieval forceps during cerebral aneurysm embolization: a case report].
Endovascular embolization for a cerebrovascular lesion has been increasingly performed. We experienced disruption of the microcatheter during a cerebral aneurysm embolization and removed the catheter fragment with retrieval forceps. A 56-year-old woman was brought to our hospital because of consciousness disturbance. ⋯ Microscopical observation of the catheter end revealed relatively sharp disruption and extension of the stainless steel blade. Microcatheter disruption and migration is a rare but significant complication of endovascular embolization. Percutaneous technique with retrieval forceps for the extraction of intravascular foreign objects was useful.
