93 year old woman; fell on back of head which resulted in large (golf ball size bump, which bruised quickly; minimal blood from small laceration). Normal basic neuro exam. Began complaining of tingling in hands and legs. Evaluated in ER, including XRay and CT Scan -- all WNL. Significant headache. Sent home. Awoke with knot on back of head much smaller, much less headache -- just feels woozy. Normal eating and sleeping; continues to use walker for balance. Now at 48 hours, she has started developing left black eye. Could they
have missed a basilar skull fracture in the XRay/CT? Is it important to be rechecked?
