Clinical narrative: 12 yo male presenting with bilateral lower extremity paresthesias and confusion.  Admitted to the hospital.  Pending discharge to rehab facility.  ED Note 5/19/21 Patient is a 12-year-old male with hypogammaglobulinemia, asthma, IBS who presents with weakness in his lower extremities.   6 days ago, patient had seafood and later that night vomited once, nonbloody, nonbilious. 4 days ago, he received the first dose of the Pfizer SARS-CoV2 vaccination. That day, he also felt some burning over the anterior parts of his bilateral ankles. Over the past 3 days, he has been sleeping a lot and had a headache. He has not had a fever or other muscle aches, no subsequent N/V, abdominal pain. Last night, he reported ankle pain to his mom. Today at school, he was playing kickball when he had the sensation that his ankles were not working/gave out and he fell to the ground. He had difficulty getting up and required a wheelchair. He did not lose consciousness, denied CP, palpitations, SOB, headache, vision change during or before that episode. He was not incontinent of urine/stool and had no abnormal movements noted at the time. Since then he has noted twitching in his thighs, calves and toes. He reports weakness throughout both lower extremities and has difficulty with intentional movements at the toes/ankles/knees, weakness in hips. He reports a burning sensation over the anterior ankles/dorsum of foot b/l. Denies fevers, chills, cough, SOB, CP, palpitations, abdominal pain, N/V/C. He endorses diarrhea 3x daily which is his baseline. He has panic attacks 3x daily w palpitations/SOB that self resolve. He has been on keflex for an ingrown toe nail for the last week.  MRI performed with normal brain and spine.  However, on repeat exam patient has diminished sensation in the bilateral feet and diminished ability to dorsiflex or plantarflex both ankles with very limited toe range of motion.  Still with preserved reflexes in the patella and Achilles.  Discussed at length with neurology and the family.  Differential diagnosis at this point of functional neurological disorder versus Guillaine Barré syndrome.   Neurology note 5/21/21 Patient is a 12yo M with hypogammaglobinemia, IBS, and poorly controlled anxiety, presenting with 4 days of lower extremity paresthesias and 1 day of hyperacute onset of lower extremity weakness and perhaps some mild confusion.   History notable for covid vaccine three days prior to presentation and anixety surrounding covid and return to school. His general examination is notable for anxious affect with difficult to localize neurologic exam. Exam shows possible bilateral lower extremity weakness of TA and hamstring>quad/IP that is very challenging to grade due to poor effort and giveway, and decreased sensation in a bilateral stocking/glove distribution to all sensory modalities.  MRI w/wo contrast brain and spinal cord normal on admission. LP perfromed in ED also normal. Given negative workup and history of anxiety with recent psychosocial stressors, most likely sudden onset weakness is secondary to a functional neurologic disorder.  Plan for discharge to rehab pending PT evaluation.
