1D01.10 Meningitis due to Cryptococcus neoformans

Definition of Meningitis due to Cryptococcus neoformans: Inflammation of the pia and arachnoid and spinal fluid associated with the fungus cryptococcus neoformans. The respiratory tract is the usual portal of entry and meningitis may occur after dissemination to the meninges from the lungs. C neoformans meningitis tends to occur in patients with defective cellular immunity. The meningits usually evolves sub acutely, but may be acute. Clinical features include headache, fever, nausea and vomiting, meningismus, visual disturbances, abnormal mental status, seizures, and raised intracranial pressure. Headache, fever, and stiff neck may be absent. The diagnosis is made by microscopic examination of the spinal fluid, culture of CSF and blood, and the latex agglutination test to detect the capsular polysaccharide antigen in CSF and blood. The organism may be seen on Gram stain or India ink stain of the CSF. The spinal fluid usually shows varuable lymphocytic pleocytosis, a low glucose content, and a high protein level.

Infectious abscess of the central nervous system

ICD 11 Code For Infectious abscess of the central nervous system

1D03  Infectious abscess of the central nervous system

Definition of Infectious abscess of the central nervous system: A focal suppurative process of the brain parenchyma, the intracranial or spinal epidural or subdural space, and less commonly the spinal cord parenchyma. The suppurative process is most commonly associated with bacterial infection, and occasionally with fungal, protozoal, or parasitic infection. Brain abscesses develop most commonly by spread from a contiguous infected site (ear, paranasal sinuses, mastoid air cells, teeth), craniofacial osteomyelitis, and following open head trauma or previous neurosurgical procedure. Haematogenous spread from purulent pulmonary infections, bacterial endocarditis, or other sites of infection, can also cause brain abscess . Patients with intracranial abscess present with variable combinations of headache, altered mental status, focal deficits, and seizures. Fever may be present. Patients with intraspinal abscess present with variable degrees of paraparesis or quadriparesis, sensory impairment below the level of the lesion, altered sphincter function, and back pain. The diagnosis is made by CT or MRI imaging, and may be confirmed by histological examination and culture of the abscess material following neurosurgical drainage. Lumbar puncture is usually contraindicated.

1D03.33 Multiple or widespread intracranial abscess

Definition of Multiple or widespread intracranial abscess: Multiple focal suppurative infections within the cranial cavity, including the epidural and subdural spaces, or in the brain, brainstem or cerebellum. The abscesses are typically surrounded by a vascularised capsule. Cerebritis describes nonencapsulated brain abscesses. The infective agent may be bacterial, fungal, or parasitic. The signs and symptoms are variable but typically present as an expanding mass lesion, over a variable period of time, with headache, fever, and a focal neurologic deficit. Seizures may occur. Diagnosis is made by neuroimaging. Microbiologic diagnosis is made by gram stain and culture of abscess material.

This condition is characterised by a focal accumulation of purulent material within the epidural space. This condition presents with symptoms depending on the location of the abscess. Transmission is through haematogenous spread of the infectious agent commonly from a cutaneous or mucosal source.
