A patient with a history of pain, paresthesias, and weakness in both legs is reported. Magnetic resonance imaging (MRI) of the lumbar spine demonstrated subacute subdural hematoma. Brain MRI obtained 1 day later because of progressive headache showed hemorrhagic cortical metastasis and extensive subdural hematoma. It is hypothesized that the lumbar hematoma originated from the intracranial bleeding, which was substantiated by the observation of a thin hemorrhagic collection connecting cranial and lumbar hematomas on MRI. Cranial origin should be included in the differential diagnosis of spontaneous spinal subdural hematomas.
We present the case of a 45-year-old woman presenting with a spontaneous cerebrospinal fluid (CSF) rhinorrhoea. A CSF leak, arising from a posterior ethmoidal left cell, was closed using an underlay procedure with a turbinate composite graft with applied fibrin glue. Twenty-three months later the CSF rhinorrhoea recurred. Recurrence was imputed to morbid obesity (BMI 48) responsible for benign intracranial hypertension. The patient underwent a laparoscopic adjustable gastric banding. CSF rhinorrhoea gradually decreased during the 12 months following surgery, in correlation with the weight loss, until total resolution was achieved. To our knowledge, this is the second reported case of a spontaneous CSF leak treated by bariatric surgery. This observation strengthens the theory that severe obesity can cause benign intracranial hypertension which can lead to CSF leak.
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.
