Disease Injury Nutrition Poison ... Amebic brain abscess Brain abscess Definition: A brain abscess is a mass of immune cells, pus, and other material that can occur when the brain is infected by bacteria or fungus. Alternative Names: Abscess - brain; Cerebral abscess; CNS abscess Causes, incidence, and risk factors: Brain abscesses commonly occur when bacteria or fungi infect part of the brain. Inflammation develops in response. Infected brain cells, white blood cells, and live and dead microorganisms collect in a limited area of the brain. This area becomes enclosed by a membrane that forms around it and creates a mass. While this immune response can protect the brain by isolating the infection, it can also do more harm than good. The brain swells in response to the inflammation, and the mass may put pressure on delicate brain tissue. Infected material can block the blood vessels of the brain, further damaging tissues by causing cell death and swelling of additional cells. Multiple abcesses are uncommon except in immunocompromised patients. Infectious agents gain access to the brain in several ways. The most common way is through infected blood. Ear and sinus infections may also spread directly to the brain because of their close proximity.

A 20-year-old woman with the acquired immunodeficiency syndrome presented with headache and fever. Nocardia asteroides was cultured from a stereotaxic brain biopsy specimen. Despite antibiotic therapy to which the pathogen was sensitive, resolution of the abscess followed only after complete surgical excision.

ABSCESS Bacterial Brain abscesses may be related to infections of the paranasal sinuses, mastoids, middle ears as well as hematogenous seeding, but in 20% of cases a source is not discovered. Very rarely an abscess is secondary to meningitis. In children, more than 60% of cerebral abscesses are associated with congenital heart disease and right to left shunts. Presenting symptoms of a cerebral abscess include headache, drowsiness, confusion, seizures and focal neurologic deficits. Fever and leukocytosis are common during the invasive phase of a cerebral abscess but may resolve as the abscess becomes encapsulated. Organisms most frequently cultured from brain abscesses in otherwise immunocompetent individuals are staphylococcus and streptococcus. When the brain is inoculated with a pathogen, a local cerebritis develops. Pathologically, an area of cerebritis consists of vascular congestion, petechial hemorrhage and brain edema. The infection goes through a stage of cerebral softening, followed by liquefaction and central cavitation. With time, the central necrotic areas become confluent and are encapsulated after one to two weeks. Edema, a prominent feature of cerebral abscess, may actually subside after the capsule forms. In the cerebritis stage, MR reveals high signal intensity on T2-weighted images, both centrally from inflammation and peripherally from edema. Areas of low signal are variably imaged on T1-weighted scans. As the progression to abscess ensues there is further prolongation of T1 and T2 centrally. The capsule becomes highlighted as a relatively isointense structure containing and surrounded by low signal on T1- weighted images, and high signal on T2-weighted images. Mottled areas of enhancement are seen with gadolinium-enhanced MR during the cerebritis stage, with an enhancing rim developing as the abscess matures. The enhancing rim may appear late in the cerebritis stage, prior to actual central necrosis. In some instances, the central area of necrosis has also enhanced on delayed scans, but not as commonly as is seen in necrotic tumors.

77. Amoebic Liver Abscess By Dr. O.P. Kapoor The symptoms of an amoebic cerebral abscess simulate a pyogenic cerebral abscess,differing only in theseverity and the rapid progress often seen in former. http://www.bhj.org/books/liver/s6c01.htm

UNCOMMON COMPLICATIONS CHAPTER CONTENTS General Complications Local complications Complications of associated colon lesions Iatrogenic complications The complications of an amoebic liver abscess can be so widespread that it can involve any part of the body. The following complications are encountered less often than those which have already been discussed. Evidently the surgeons and pathologists are more familiar with the rare type of complications. Involvement of organs distant from the liver, beyond doubt, is due to the blood-borne infection. Such a distribution does not follow any set pattern as regards the frequency, site, number of lesions and their severity. Post-mortem studies have enlightened us to a great extent as to the site, number and frequency of the rare types of the lesions. The complications of an amoebic liver abscess can be divided into AA) General complications (B) Local complications.

Letters to the Editor Cerebral Toxoplasmosis in a Patient with AIDS Sir, Toxoplasmosis is the most well known frequent cause of intracranial mass lesions in patients with AIDS, accounting for 50-70% of all mass lesions in this population . It is also the most common opportunistic infection involving the brain in patients with AIDS. The probability of ever developing toxoplasma encephalitis after the onset of AIDS has been estimated at 28%. It is said to be the most eminently treatable among all the CNS infections in this population . However, a high index of suspicion is necessary so as not to miss the diagnosis in a new patient. This communication becomes important because of the sequence of events that lead to the diagnosis, though the disease itself is very common in HIV positive patients. A thirty-six-year-old gentleman was admitted to our hospital with a history of right-sided weakness and difficulty in talking for one week. Neurological examination revealed right pyramidal signs. There was global aphasia and the fundi showed bilateral papilledema. Since there was chronic suppurative otitis media of the left ear, a brain abscess was suspected and a CT was performed. Plain scans showed a hypodense lesion with an isodense peripheral margin involving the left basal ganglia, thalamus and left frontoparietal lobe associated with surrounding edema and mass effect (Fig. 1). The contrast enhanced scans showed mild ring enhancement of the isodense margin (Fig. 2). The diagnostic possibility of a brain abscess or a granulomatous lesion such as a tuberculoma was considered. The patient was started on an anti-TB regime with steroids, on an empirical basis.

Sagittal post contrast MRI reveals a ring enhancing mass adjacent to abnormally thickened and enhancing meninges. These findings are compatible with a diagnosis of cerebral abscess and meningeal inflammation/infection. Diagnosis: cerebral abscess. The axial MRI with contrast shows a septated subdural empyema seen as a peripherally-enhancing extra cerebral fluid collection. Diagnosis: Subdural abscess.
