Intracranial abscess is one of the most serious complications of frontal sinusitis, particularly among adolescents, even in the absence of odontogenic infection. Polymicrobial infections due to anaerobes are common. Because antibiotic therapy alone is usually ineffective, early endoscopic sinus surgery is the key for infection control and good clinical outcomes.

Actinomycosis is a chronic, suppurative, bacterial disease characterized by extensive fibrosis, occasional granulomas, abscess formation, and sinus discharge containing sulfur granules. In actinomycosis, the CNS is involved in only 3.3% of cases [1]. This report documents an actinomycotic granuloma simulating a trigeminal neuroma clinically, radiologically, and surgically. It is also the first ...

Orbital cellulitis and abscess formation are uncommon complications of sinusitis. Early diagnosis and treatment are important to prevent blindness and intracranial complications. We present four consecutive cases referred over 2 years which demonstrate how diagnostic delays may occur and suggest a protocol to avoid similar delays.

A young girl developed an intracranial abscess and necrotizing cellulitis following penetrating injury from a lawn dart. Initial identification of a gram-positive rod growing aerobically from clinical specimens was as a Bacillus organism, but the observation that the isolate grew poorly in subcultures for susceptibility testing but quite well under standard anaerobic culture techniques led to t...

Intracranial complications secondary to ear infections is an established clinical condition. The proximity of the brain compartments to the ear increases the chances of infections being percolated to central nervous system. Early clinical and laboratory diagnosis of such infections and better patient management strategies are required to minimize the intracranial and extracranial complications....

After the operation for mastoid. (a) When the temperature is raised the dura should not be opened, nor the brain explored by a needle. If this is done the patient will rarely, if ever, survive. With the subsidence of temperature there may be a complete disappearance of the signs of increased intracranial tension with recovery. (b) When the temperature is not raised and there is strong indicatio...

DESCRIPTION A 19-year-old male with periorbital painful swelling, headache and vomiting was admitted to our clinic. Because of the diagnosis of sinusitis he had received medical treatment in another center two months before, consisting of antibiotics and analgesics. However as a result of valid persistence of the patients' complaints, brain CT and MR imaging were required; showing bilateral epi...

Patients with penetrating head trauma with retained projectiles develop intracranial abscesses as a common complication. The most common presentation is a suddenly worsening headache. The most common pathogen identified is staphylococcus. Outcomes are related to adherence of Matson's tenets. This case study details the presentation of a 19-year-old patient that presented to the neurological sur...

Nocardia otitidiscaviarum belongs to the agents of opportunistic infections seen in immunocompromised patients, but may occur rarely in immunocompetent patients. In this report we described a case of a previously healthy 69-year-old woman with cerebral and retroperitoneal abscess due to Nocardia otitidiscaviarum. The patient was admitted to hospital because of loss of strength in her right arm ...

Bacterial brain abscess is still a disease that challenges neurosurgeons in its diagnoses and treatment, in both adults and children because of variations in the microbiological features, and altered immune status (for example, due to HIV infection, treatment with chemotherapy or organ transplantation). The incidence of brain abscesses is ~ 8% of intracranial masses in developing countries, whe...
