Diagnostic Challenges of Lyme Neuroborreliosis in Inpatient Neurology: A Case Series.

Lyme disease is a multisystem disorder transmitted through the Ixodes tick and is most commonly diagnosed in northeastern and mid-Atlantic states, Wisconsin, and Minnesota, though its disease borders are expanding in the setting of climate change. Approximately 10%-15% of untreated Lyme disease cases will develop neurologic manifestations of Lyme neuroborreliosis (LNB). Due to varying presentations, LNB presents diagnostic challenges and is associated with a delay to treatment.

Ischemic cerebrovascular complications with initial presentation of genetic atypical hemolytic uremic syndrome.

Background: Atypical hemolytic uremic syndrome (aHUS) is a rare disease, with scarce reports of neurologic manifestations in the acute setting. Ischemic cortical infarcts concurrently with aHUS presentation have not been described in adult patients.

Case Description: A 46-year-old male presented with acutely declining mental status and progressive weakness, in the setting of longstanding hypertension and known type B aortic dissection.
