The range of disorders affecting the cerebral veins and sinuses is increasing and now includes blood disorders, abnormalities in the patterns of blood flow, and infiltrative or inflammatory conditions, all of which may promote thrombosis. We describe 10 patients with cerebral venous thrombosis: two had protein S deficiency, one had protein C deficiency, one was in early pregnancy, and there was a single case of each of the following: dural arteriovenous malformation, intracerebral arteriovenous malformation, bilateral glomus tumours, systemic lupus erythematosus, Wegener's granulomatosis, non-Hodgkin's lymphoma. The recognition of such diverse aetiology may be importance since clinical features are non-specific, and may consist only of raised intracranial pressure, allowing confusion with 'benign intracranial hypertension'. The existence of effective treatment both for the thrombosis and for many of the underlying disorders makes early diagnosis essential. The prognosis of treated patients may be favourable.

Spontaneous intracranial hemorrhage (ICH) is a rare but devastating complication in patients with chronic immune thrombocytopenic purpura (ITP). We report four patients with chronic ITP unresponsive to steroid treatment who developed ICH. One patient had systemic lupus erythematosus; in another patient, the ICH originated from an arteriovenous malformation. High dose steroids, platelet concentrates, emergency splenectomy, and subsequent evacuation of intracranial hematoma, if necessary, can lead to a reasonable outcome of ICH in patients with chronic ITP.

Acute transverse myelitis (ATM) with moderate symptomatology and smaller multiple magnetic resonance imaging lesions is often caused by multiple sclerosis. Severe ATM with extensive magnetic resonance imaging lesions with or without associated meningitis often has a viral cause, particularly in the younger age groups, whereas vascular disorders may prevail among older patients. Previously, one had to rely on indirect evidence such as viral serology or viral identification in throat washings to confirm a diagnosis of myelitis. Thus, mycoplasma myelitis may occur coincident with a mycoplasma pneumonia. Viral myelitis is now often diagnosed by specific polymerase chain reaction of the cerebrospinal fluid, for echovirus, Coxsackie virus, mumps virus, herpes simplex virus or varicella-zoster virus, but an autoimmune component may still be important. An anterior horn syndrome may be produced by the tick-borne encephalomyelitis virus. Severe ATM may also be a postinfectious or postvaccinal disorder [i.e. a partial acute disseminated encephalomyelitis (ADEM)]. Neuromyelitis optica, a combination of severe myelitis and optic neuritis, is often a manifestation of ADEM or systemic lupus erythematosus. Many of these disorders are potentially treatable with specific antiviral agents or immunosuppression. 'Idiopathic' ATM is probably a consequence of inadequate examination and follow up. The differential diagnoses-viral myelitis, multiple sclerosis, ADEM, neuromyelitis optica, spinal arteriovenous malformation and arteritis-should be considered and are usually identified by a rapid diagnostic work-up, leaving few ATM cases undiagnosed.

Young patients with migraine are at increased risk for stroke, particularly patients with an aura of focal neurologic deficits. Other causes of ischemia are often identified in patients with migraine, including patent foramen ovale, lupus anticoagulant, cervical carotid dissection, arteriovenous malformation, and hyperactivity of the clotting system. Migrainous stroke is only diagnosed when all other possible causes of stroke have been eliminated and the patient has irreversibility of the usual aura, associated with an ischemic infarct in the appropriate brain territory. Prophylactic therapy of migraine with aura may be beneficial in preventing migrainous stroke.
