Brain abscess
Pyogenic brain abscess is a focal collection of pus within the brain. It is initiated when bacteria gain entry into cerebral tissues with trauma, contiguous spread from a suppurative focus (in middle ear, oropharynx, & paranasal sinuses), or hematogenous dissemination from a distant infection.
Subdural empyema
pus collection in subural space. The pathogenesis of subdural empyema is similar to brain abscess.
Epidural Abscess
Osteomyelitis ( Post operative, Post Traumatic, Tubercular, Pyogenic , etc.)
Post craniotomy infections
Meningitis
Bacterial, Viral, Fungal, Tubercular
Vertebral osteomyelitis
Spinal epidural abscess
Granulomas ( Neurocysticercosis, tubercular)
Toxoplasmosis, HIV infection ( AIDS)
Blastomycosis
Histoplasmosis
Coccidiomycosis
Paracoccidiomycosis
Cryptococcosis
Sporotrichosis
Aspergillosis
Chromoblastomycosis
