Extradural hematoma (EDH) is usually a post-traumatic sequel but a few cases of spontaneous EDH have been reported. Here we report a woman who presented with spontaneous acute EDH but was later found to have dural metastasis from lung carcinoma. Causal factors have been present in all reported cases, as well as in this case. We propose the term non-traumatic EDH.
Primary pyogenic abscess in the conus medullaris in a healthy adult has never been reported. An urgent MRI scan with contrast and prompt surgical evacuation may lead to good neurological recovery.
We report the first case of ectopic prostate tissue in a lipoma of the spine. Ectopic prostate tissue is well documented at a number of sites within the human body. Ectopic prostate tissue has previously been reported in the spine but usually in the context of spinal teratomas. This case is unique in that this is the first description of the presence of benign prostatic tissue in a lipoma of the conus medullaris. This is a highly unusual finding and probably reflects divergent differentiation or a malformative process.
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.
