A brain abscess is a pus-filled swelling in the brain. Brain abscess is an important complication of both systemic and pericranial infections (sinusitis, otitis, etc.), of cranial trauma, and of neurosurgical procedures. The classic presentation of brain abscess is headache, fever, and focal neurologic signs. In most patients, however, this triad is not found, and presentation is that of a subacutely developing intracerebral mass lesion.

Reversible cerebral vasoconstriction syndromes (RCVS) are characterized by recurrent, severe “thunderclap” headaches and multifocal cerebral arterial narrowing and dilatation, often complicated by ischemic or hemorrhagic strokes or reversible brain edema. RCVS affects young individuals, mostly women, and have been associated with diverse conditions such as pregnancy, migraine, vasoconstrictive drug use, pheochromocytoma, and neurosurgical procedures. The prognosis is usually excellent, with most patients recovering completely or near-completely within days to weeks.

In horizontal gaze palsies, the supranuclear control of lateral eye movements is impaired. Palsy may be selective for some types of eye movements but not others. They can occur in congenital or acquired forms, and when acquired, usually point to damage to specific pontine structures. They are usually due to lesions of supranuclear, nuclear, and infranuclear pathways of horizontal eye movements in the pons.

Meningitis is the most common clinical manifestation of CNS histoplasmosis, which can also cause focal brain and spinal cord lesions (histoplasmomas), stroke syndromes, encephalitis, cerebritis and abscesses. CNS involvement can occur in both disseminated disease and in isolation, although isolated cases are rare. Immunocompromised patients are at greater risk for disseminated infection.

Sporadic schwannomas and neurofibromas are benign tumors that arise from the nerve sheaths of cranial nerves, nerve roots, spinal nerves, and peripheral nerves. Most schwannomas originate from the eighth cranial nerve, whereas neurofibromas more commonly arise along the spinal nerve roots and can occur in superficial (cutaneous, subcutaneous) and deep (visceral, spinal, orbital) locations. When intervention is indicated, surgical resection is the treatment of choice.
