J Korean Neurosurg Soc 48 : [281][282][283][284] 2010 Spinal epidural hematoma is a rare complication associated with pain control procedures such as facet block, acupuncture, epidural injection, etc. Although it is an uncommon cause of acute myelopathy, and it may require surgical evacuation. We report four patients with epidural hematoma developed after pain control procedures. Two procedures were facet joint blocks and the others were epidural blocks. Pain was the predominant initial symptom in these patients while two patients presented with post-procedural neurological deficits. Surgical evacuation of the hematoma was performed in two patients while in remaining two patients, surgery was initially recommended but not performed since symptoms were progressively improved. Three patients showed near complete recovery except for one patient who recovered with residual deficits. Although, spinal epidural hematoma is a rare condition, it can lead to serious complications like spinal cord compression. Therefore, it is important to be cautious while performing spinal pain control procedure to avoid such complications. Surgical treatment is an effective option to resolve the spinal epidural hematoma.
The most common cause of isolated oculomotor nerve palsy is ischemia of the peripheral nerve caused by a disease, such as diabetes mellitus. Another common cause of isolated oculomotor nerve palsy is compression by an intracranial aneurysm, usually an posterior communicating artery aneurysm. However, it is extremely rare in the pituitary tumor. We report an unusual case of pituitary adenoma presenting with isolated oculomotor nerve palsy in the setting of pituitary apoplexy. We suggest that pituitary apoplexy should be included in the differential diagnosis of a patient with isolated oculomotor nerve palsy and early surgery should be considered for preservation of oculomotor nerve function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
