Case Study 1: Facial Droop In A 22-Year-Old African American

Case Study 1 Facial Droop22 Year Old African American Female Looks In

Use the Episodic/Focused SOAP Template and create an episodic/focused note about the patient in the case study to which you were assigned using the episodic/focused note template. Provide evidence from the literature to support diagnostic tests that would be appropriate for each case. List five different possible conditions for the patient's differential diagnosis, and justify why you selected each.

Paper For Above instruction

The case involves a 22-year-old African American female presenting with facial droop, specifically noticing that the left side of her mouth appears slanted when she smiles. She reports intermittent headaches over the past few days and experiences a decrease in taste when brushing her teeth. These symptoms raise concerns about neurological and neuromuscular involvement and warrant a thorough assessment using an Episodic/Focused SOAP (Subjective, Objective, Assessment, Plan) note framework. This structured approach assists in forming an accurate diagnosis by systematically evaluating her symptoms, clinical findings, and potential differential diagnoses supported by existing medical literature.

Subjective

The patient reports noticing a left-sided facial droop, particularly when smiling, which has been persistent for a short period. She describes experiencing intermittent headaches over several days, although the severity varies. She also mentions a decreased sense of taste, especially noticeable when brushing her teeth. The patient denies any recent trauma, fever, or other neurological symptoms such as weakness in limbs, vision changes, or dizziness. She has no history of similar episodes previously and reports no known chronic illnesses. Her social history indicates she is generally healthy, with no current medication use or substance abuse. She is an African American female, which may influence certain disease prevalences.

Objective

On examination, the patient exhibits asymmetric facial movements with drooping on the left side of her mouth, evident when she smiles or attempts to mobilize her facial muscles. Cranial nerve assessment reveals decreased function of the facial nerve (cranial nerve VII) on the affected side. No other cranial nerves show abnormalities. There is no evidence of limb weakness, sensory loss, or gait disturbance. The rest of the neurological examination, including vital signs, is unremarkable. No skin rashes or signs of infection are observed.

Assessment

The clinical presentation suggests a neurological facial paralysis, with Bell's palsy being a primary consideration. Given her history, decreased taste and facial droop are characteristic signs of facial nerve involvement. The differential diagnosis includes conditions that can mimic or cause similar symptoms:

• Bell’s Palsy: Most common cause of acute facial paralysis, often idiopathic but linked to viral reactivation, particularly herpes simplex virus (HSV). Her symptoms align well with Bell's palsy features.
• Stroke or Transient Ischemic Attack (TIA): Sudden facial paralysis can be a sign of stroke; however, the absence of limb weakness, changes in consciousness, or other neurological deficits makes this less likely. Nevertheless, ruling out cerebrovascular events is crucial, especially with headache.
• Lyme Disease: Can cause facial nerve palsy, especially in endemic areas. Though less common in this demographic, it's essential to consider geographical and exposure history.
• Multiple Sclerosis (MS): Demyelinating disease that might involve cranial nerves, including facial nerve palsy, especially in young adults, with additional neurological signs.
• Tumors or Mass Lesions: Parotid gland tumors or cerebellopontine angle tumors (e.g., schwannomas) can present with facial nerve palsy, usually with progressive symptoms over time.

Diagnostic testing should aim to confirm the diagnosis, evaluate for underlying causes, and rule out serious conditions such as stroke or neoplasm.

Plan

Diagnostic tests recommended include:

• Neuroimaging: An MRI with contrast of the brain and skull base to exclude stroke, tumors, or demyelinating lesions. MRI is preferred over CT for detailed visualization of cranial nerve pathways (Glick et al., 2020).
• Serologic Tests: Lyme disease serology if there's a history of tick exposure. Testing for herpes simplex virus (HSV) may be supportive but not routine (Liang et al., 2021).
• Electroneurography or Electromyography (ENoG/EMG): To assess the degree of nerve degeneration, especially useful in atypical or prolonged cases (Murphy & Garry, 2020).
• Laboratory Tests: Basic blood work including CBC, metabolic panel, and inflammatory markers to evaluate for systemic causes.
• Referral: Consult neurology or otolaryngology for comprehensive assessment and management planning.

Management would typically include corticosteroids to reduce nerve inflammation, antivirals if viral etiology is suspected, and supportive care such as eye protection. Patient education about prognosis and recovery expectations is vital.

Conclusion

This case underscores the importance of a systematic approach to acute facial paralysis. Although Bell's palsy remains the most common cause in young adults, clinicians must diligently exclude other critical conditions such as stroke, Lyme disease, MS, or tumors through appropriate diagnostic testing. A combination of clinical judgment, detailed history, physical examination, and targeted investigations can aid in establishing an accurate diagnosis and guiding effective treatment.
