Abstract:
We report the case of a 72-year-old man with a history of Parkinson's Disease who presented with a history of falls, cognitive impairment and depressed mood. Neurological examination revealed moderate rigidity and bradykinesia. Alterations to his anti-Parkinsonian medication resulted in improvements in his mobility but no change in mental state. He was also noted to have developed multiple raised skin lesions. One of these lesions was biopsied and grew Cryptococcus neoformans. He subsequently had a cerebral MRI scan which showed enhancing lesions, in the left parietal lobe and right superior cerebellar peduncle, consistent with intracranial cryptococcal infection. Images of one of the skin lesions and the cerebral MRI scan are shown.
Insights
This case study highlights a 72-year-old man with Parkinson's Disease who developed Cryptococcus neoformans infection. The infection manifested as skin lesions and intracranial lesions, impacting his cognitive state.
Area of Science:
- Neurology
- Infectious Diseases
- Dermatology
Background:
- Parkinson's Disease (PD) management can be complex, with patients experiencing various non-motor symptoms.
- Co-infections can complicate the clinical presentation and management of neurodegenerative diseases.
Observation:
- A 72-year-old male with a history of Parkinson's Disease presented with falls, cognitive decline, and depressed mood.
- The patient developed multiple raised skin lesions.
- Neurological examination revealed rigidity and bradykinesia, with limited improvement in mental state after medication adjustment.
Findings:
- Biopsy of a skin lesion identified Cryptococcus neoformans.
- Cerebral MRI revealed enhancing lesions in the left parietal lobe and right superior cerebellar peduncle.
- These findings were consistent with intracranial cryptococcal infection.
Implications:
- Cryptococcal infections should be considered in the differential diagnosis of patients with Parkinson's Disease presenting with neurological and dermatological changes.
- Early diagnosis and treatment of Cryptococcus neoformans are crucial for managing co-infections in immunocompromised or neurologically compromised patients.
- This case underscores the importance of a multidisciplinary approach in managing complex neurological conditions with superimposed infections.
