A 70 year-old female presents to your office accompanied by her father, who provides most of the history.
The father states that for the past 5 years, the patient has been distressed from seeing visions of flirtatious violet peregrine falcons, developed a tremor, has had periods when she is lethargic and drowsy, and others when she is more alert, has complained of stiffness, has fallen several times, and has been having progressively worsening memory problems.
Which of the following pathology findings is MOST characteristic of this patient's disease?
A) Amyloid plaques B) Basophilic nuclear inclusions C) Eosinophilic cytoplasmic inclusions D) Punctate hemorrhages in periaqueductal grey and in the grey matter surrounding the 3rd and 4th ventricles E) Eosinophilic nuclear inclusions

ANSWERS AND EXPLANATIONS
A) amyloid plaques
This answer is incorrect.
This patient's history is consistent with dementia with Lewy bodies (DLB). Patients with DLB develop Parkinsonian symptoms and dementia symptoms at approximately the same time. Other key clinical features include recurrent visual hallucinations and fluctuations in mental status. Amyloid plaques are seen in DLB, but widespread Lewy bodies are a more defining feature. (

B) basophilic nuclear inclusions
This answer is incorrect.
This patient's history is consistent with dementia with Lewy bodies (DLB). Patients with DLB develop Parkinsonian symptoms and dementia symptoms at approximately the same time. Other key clinical features include recurrent visual hallucinations and fluctuations in mental status. Lewy bodies are eosinophilic cytoplasmic inclusions. (

C) eosinophilic cytoplasmic inclusions
This answer is correct.
This patient's history is consistent with dementia with Lewy bodies (DLB). Patients with DLB develop Parkinsonian symptoms and dementia symptoms at approximately the same time. Other key clinical features include recurrent visual hallucinations and fluctuations in mental status. Lewy bodies are eosinophilic cytoplasmic inclusions which contain alpha-synuclein. (

D) punctate hemorrhages in periaqueductal grey and in the grey matter surrounding the 3rd and 4th ventricles
This answer is incorrect.
This patient's history is consistent with dementia with Lewy bodies (DLB). Patients with DLB develop Parkinsonian symptoms and dementia symptoms at approximately the same time. Other key clinical features include recurrent visual hallucinations and fluctuations in mental status. Punctate hemorrhages in periaqueductal grey and in the grey matter surrounding the 3rd and 4th ventricles are seen in Wenicke encephalopathy. (
