Abstract The bacteriological and clinical findings in 19 pediatric patients with intracranial abscess are presented. Ten children presented with subdural empyema and nine had brain abscess. [ncbi.nlm.nih.gov]

• Fever

  The patient experienced photophobia, fever, headache, nausea and vomiting. Frontal sinusitis with intracranial abscess was diagnosed on imaging. The patient was taken to the operating room for drainage with left frontal balloon sinuplasty. [ncbi.nlm.nih.gov]

  Signs and symptoms [ edit ] Fever, headache, and neurological problems, while classic, only occur in 20% of people with brain abscess. [2] The famous triad of fever, headache and focal neurologic findings are highly suggestive of brain abscess. [en.wikipedia.org]

  Fever, chills, and leukocytosis may develop before the infection is encapsulated, but they may be absent at presentation or subside over time. [merckmanuals.com]

  Clinically, the patients usually present with vomiting, fever, headache, seizures, focal neurologic signs and eventually, papilloedema and coma, but these manifestations can be subtle in the initial stages [ 3, 5 ]. [omicsonline.org]

  Common presenting symptoms include fever, headache, changes in mental state (drowsiness, confusion), focal neurological deficits, grand mal seizures, nausea and vomiting, neck stiffness. [patient.info]

• Inflammation

  Inflammation in the brain can lead to problems such as vision loss, weakness and paralysis. Loss of brain cells, which happens if you suffer a stroke, can affect your ability to think clearly. [icdlist.com]

  Condition Intracranial abscess Brain abscess (or cerebral abscess) is an abscess caused by inflammation and collection of infected material, coming from local (ear infection, dental abscess, infection of paranasal sinuses, infection of the mastoid air [symcat.com]

  This can happen when inflammation damages the barrier, leading to gaps. The infection enters the brain through three main routes. [medicalnewstoday.com]

  These complications take time to develop and may appear after the inflammation has subsided. They may be prevented by prompt treatment. [neuropathology-web.org]

  In the following 12 months he required 5 major surgeries due to a process of systematic inflammation/infection throughout different locations of the DBS system. [revistaneurocirugia.com]

• Epilepsy

  Epilepsy. A small number of people go on to develop epilepsy, a condition that causes repeated fits or seizures. Epilepsy is a long-term condition and symptoms can usually be controlled using medication. [hse.ie]

  Epilepsy occurs long-term in 30-50%, particularly with temporal lobe abscess and subdural empyema. Anticonvulsants may be required. [patient.info]

  Epilepsy as a sequel occurred in 21% of the cases. The fact that mortality continues to be high is attributed to the degree of impairment of consciousness of the children at the time of admission. [link.springer.com]

• Malaise

  Clinical features: The earliest stage where the brain tissue is invaded (stage of encephalitis) is marked by the presence of headache, fever, malaise and vomiting. Drowsiness eventually follow. [sites.google.com]

  Symptoms include fever, malaise, irritability, severe headache, convulsions, vomiting, and other signs of intracranial hypertension. [medical-dictionary.thefreedictionary.com]

• Seizure

  Fifteen months after surgery, he visited a neurologist after having a seizure and was treated with anticonvulsants. After a second episode of seizure, imaging studies showed a temporal lobe abscess. [ncbi.nlm.nih.gov]

  Within all the people who go to their doctor with intracranial abscess, 68% report having seizures, 58% report having low back pain, and 58% report having back pain. [symcat.com]

  Patients presenting with seizures require intubation and hyperventilation. Seizures should be treated aggressively to decrease the risk of increases in intracranial pressure. [patient.info]

  If seizures are a problem you may need anticonvulsant medications, which may continue even after the abscess has been successfully treated. [drugs.com]

  These include: slurred speech muscle weakness or paralysis seizures occurring in a person with no previous history of seizures If you or someone you know experiences any of these symptoms, phone 999 immediately and ask for an ambulance. [nhs.uk]

• Altered Mental Status

  Signs of rupture include severe headache, neck stiffness and altered mental status. [clinicaladvisor.com]

• Stupor

  If this stage progresses rapidly to generalised encephalitis before it could be contained by the formation of the capsule, drowsiness may progress to stupor and coma followed by death.. [sites.google.com]

  We do know that patients that present with rapid progression that present in stupor or coma, or have spread of infection into the ventricles tend to have a poor prognosis. [coursera.org]

  It is unusual to require an emergent neurosurgical procedure for abscess, but a consultation should be considered if the patient has severe mass effect, is comatose, stuporous or has a capsule larger than 2 cm. B. [clinicaladvisor.com]

  The mental status for patients was classified into two groups: (i) clear consciousness; and (ii) inattention, confusion, clouded consciousness, stupor, or coma. Surgical intervention and/or antibiotic therapy were the mainstays of our treatment. [academic.oup.com]

Central nervous system (CNS) infections due to MAC are exceedingly rare and carry a poor prognosis. Additionally, such infections are largely reported in patients infected with HIV. [ncbi.nlm.nih.gov]

(Outcomes/Resolutions) Multiple Brain Abscesses and abscesses located deep within brain tissue are associated with bad prognosis When the patient presents with coma or advanced neurological damage, it indicates an unfavorable prognosis. [dovemed.com]

Prognosis [ 8 ] Mortality ranges between 17% and 32%. Poor prognosis is reported in patients who are immunocompromised, have diabetes mellitus or cirrhosis and presentation with a low Glasgow Coma Score. [patient.info]

Prognosis is most closely related to the patient's neurological status at presentation. [bestpractice.bmj.com]
