During surgery, a whitish firm, cartilaginous tumor compressing the S1 nerve root was discovered and excised. A narrative review of the literature was conducted, analyzing case reports and series of lumbar spinal chondromas published between 1900 and October 2025.

Distinguishing between psychosis-related catatonia and a PD off phenomenon presents a significant diagnostic challenge. We describe the case of a 48-year-old male with PD and depression who was admitted to a psychiatric ward following an episode of aggressive behavior and persecutory delusions. During hospitalization, he developed mutism, rigidity, and immobility - initially interpreted as catatonia. A Bush-Francis Catatonia Rating Scale score of 16 was documented, but a lorazepam challenge failed to elicit improvement. These symptoms coincided with the tapering of dopaminergic therapy, particularly pramipexole. Neurological consultation on hospital day 11 identified the presentation as a severe PD off state. Restoration of dopaminergic therapy, focusing on extended-release formulations and optimized timing, resulted in marked clinical improvement within 1 week. Dopamine agonists were avoided due to concern for exacerbating psychosis. This case highlights the importance of distinguishing catatonia from PD off states in patients with overlapping motor and psychiatric symptoms.
