
Present with one of 3 syndromes
 Subacute
progression of focal neurologic deficit
 Seizure
 Nonfocal
neurologic deficit: Headache
Fever, malaise, weight loss, anorexia suggest
metastatic more than primary
 Uniformly enhancing mass lesion in
immunocompetent
 Ring enhancing in the immunocompromised


Most commonly originates from:
 Lung
CA




Cause: Streptococcus (40%), Anaerobes, Staphylococcus
(10%)
Associated with otitis, mastoiditis, dental infections or
head trauma
Headache is the most common symptom in >75% of
cases
Classic triad of headache, fever, and focal neurologic
deficit
Multiple  hematogenous  poorly encapsulated

Tuberculoma
Uncommon manifestation of CNS tuberculosis
 Cause: Mycobacterium tuberculosis
 Transmission: Hematogenous spread from a
primary pulmonary or postprimary pulmonary
disease
 Seizures or focal neurologic deficits
 Diagnosis: AFB on CSF


Neurocysticercosis
Cause: Taenia solium
 Transmission: Ingestion of undercooked pork
 Cysticerci found anywhere in the body but are
commonly in:

 Brain
 CSF
 Skeletal
muscle
 Subcutaneous tissue
 Eye
Neurocysticercosis
Often presents with seizures and signs of
increased intracranial pressure
 Diagnosis:
 Fecalysis
 Neuroimaging
 Evidence of cysticercosis outside the CNS


Cryptococcosis
Cause: Cryptococcus neoformans
 Transmission: inhalation of yeast from the
environment (bird droppings)
 Risk factor: CD4 < 100
 Presents with headache, fever, cranial nerve
paresis, and meningeal irritation
 Diagnosis: India ink stain, CALAS


Toxoplasmosis




Cause: Toxoplasma gondii
Transmission: Ingestion of faecally
contaminated material, Ingestion of
undercooked meat
Risk factor: CD4 < 100
Asymptomatic in immunocompetent people
Toxoplasmosis

In immunocompromised, mainly involve the
CNS
Altered mental status (75%)
 Focal neurologic deficits (60%)
 Headaches (56%)
 Seizures (33%)

Nonfocal to focal
neurologic deficits
Meningeal involvement
uncommon
CSF often unremarkable,
may have modest increase in
cell count & protein but
normal glucose
CD4 < 100

Absence of meningismus
Sugar 64 (nv 40-75); Protein
47.4 (15-45)
CD4: 53
Clinical Correlation
Toxoplasmosis
Patient JE
(+) IgG titers detected as
early as 2-3 weeks after
infection
Multiple discrete high signal
foci, heterogenous w/ wellcircumscribed margins, and
hyperintense on post
contrast MRI
Toxoplasma IgG 3.8 (<2)
Toxoplasma IgM normal
Multiple ring enhancing
lesions with vasogenic
edema in both cerebral
hemispheres at the
corticomedullary margin
Final Diagnosis



Cerebral Toxoplasmosis
HIV infection
Atopic Dermatitis
Management


Toxoplasmosis is rapidly fatal if untreated
Treatment of choice:
 Pyrimethamine plus folinic acid plus sulfadiazine
 Pyrimethamine plus folinic acid plus clindamycin
Danneman et al. Ann Intern Med 1992; 116:33-43.
6 weeks therapy at least, or until 3 weeks after
complete scan resolution
 Corticosteroids for raised intracranial pressure

Cohn et al. Am J Med 1989; 86: 521-7
Management


Oral co-trimoxazole is effective in doses of 2
tablets 4 times daily for 1 month followed by 2
tablets twice daily as secondary prophylaxis for
life
Lifetime prophylactic therapy for toxoplasmosis
would only apply if patients are not receiving
antiretroviral therapy with the CD4 count being
under 200 cells/μl
