A 14-year-old female presented with headache, vomiting, and a rash. She was found to have papilledema and herpes zoster. Examination of the cerebrospinal fluid revealed pleocytosis and an elevated protein concentration. Varicella-zoster virus deoxyribonucleic acid was detected in the cerebrospinal fluid by polymerase chain reaction. Intracranial hypertension was treated by repeated lumbar puncture and with acetazolamide. This case represents an unusual complication of the reactivation of varicella-zoster virus.

Raised intracranial pressure in association with spinal meningeal cysts has rarely been reported. We describe four patients in whom evidence of paroxysmal raised intracranial pressure was found in association with spinal meningeal cysts. Cerebrospinal fluid diversion procedures have previously been shown to relieve local symptoms due to spinal cysts. In our patients symptoms of paroxysmal headache were alleviated by this method, suggesting a causal relationship with the raised pressure. This association may be an under diagnosed cause of paroxysmal headaches. We review the medical literature on the classification of spinal meningeal cysts, evaluate the theories of their origin and offer suggestions on the pathogenesis of the abnormal CSF dynamics that may allow an interplay between raised intracranial pressure and spinal meningeal cysts to produce paroxysmal symptoms.

Cerebral hemodynamic and metabolic changes in intracranial hypertension associated with sinus thrombosis have not been well documented. We report pre- and post-treatment changes in cerebral hemodynamic and metabolic parameters in a 50-year-old male who presented intracranial hypertension due to sinus thrombosis, using single-photon emission computed tomography (SPECT) and positron emission tomography (PET). He complained of headache, nausea and double vision and was admitted to our hospital. Neurological examinations on admission revealed papilledema on both sides. Cerebrospinal fluid pressure was 28 mmHg. Cerebral angiography showed occlusion of the superior sagittal sinus and retrograde filling of the ascending cortical veins in the bilateral frontal lobes. 123I-IMP SPECT and 15O-gas PET showed a reduction of cerebral blood flow and oxygen metabolism and an extreme elevation of cerebral blood volume in the bilateral cerebral hemispheres. His complaints resolved after lumbo-peritoneal shunt. Postoperative SPECT/PET studies demonstrated improvement of hemodynamic and metabolic parameters. Intracranial hypertension and associated venous congestion were most likely related to hemodynamic and metabolic abnormalities.

A young, non-obese woman aged 24 years with normal blood pressure developed intracranial hypertension after the oral use of tetracycline. Neuro-ophthalmologic examination revealed severely reduced acuity, papilledema, and concentric impaired visual fields. She was treated with acetazolamide and recurrent lumbar punctures and recovered, but without improvement in either acuity or visual fields. Intracranial hypertension is a fairly rare disease characterised by increased intracranial pressure without structural abnormalities in the brain or hydrocephalus, and is termed idiopathic in the absence of an underlying cause. Tetracycline should be considered as a cause of intracranial hypertension if a patient complains of previously unknown headache a few days after its ingestion. Headache and the presence of bilateral papilledema, decreased visual acuity and visual-field defects are indications for urgent referral to a neurologist. Therapy consists of a combination of repetitive lumbar punctures and medication. Surgical interventions include lumboperitoneal shunting and optic nerve fenestration. Intracranial hypertension may lead to irreversible decreased visual acuity and visual-field defects resulting in disability.

Headache in glioblastoma patients often indicates raised intracranial pressure by either tumor edema or tumor progression. We report local glioblastoma growth causing cranial nerve lesions as well as trigeminal neuralgia, and highlight pain management in these patients.

Colloid cyst of the third ventricle is a rare benign intracranial lesion, and familial cases are rarer still. They may be asymptomatic or present with symptoms of raised intracranial pressure, including sudden death. Surgical excision is curative. We report a 24 year old pregnant woman with familial colloid cyst, who presented with headaches and suffered a cardiorespiratory arrest. Early computed tomography scan of the brain is advised in patients with a family history of third ventricular colloid cyst presenting to the accident and emergency department with headache.

We present the case of a man who presented with headache and severe papilloedema which was caused not by chronic intracranial hypertension but by paroxysms of raised intracranial pressure, and we speculate what relationship this disorder has to idiopathic intracranial hypertension.

Pseudotumor cerebri is a clinical syndrome characterized by raised intracranial pressure with normal ventricular size, anatomy and position. Headache, vomiting and diplopia are the most common symptoms. Signs include those of raised intracranial pressure including papilledema and absence of focal neurological signs. A secondary cause is identifiable in 50% of children; the most common predisposing conditions are otitis media, viral infection and medications. Management is mainly directed towards identifying and treating the cause and measures to reduce the raised intracranial pressure. Though it is mostly a self limited condition, optic atrophy and blindness can occur. Oculomotor nerve palsy is very rarely associated with pseudotumor cerebri. We report a unique case of pseudotumor cerebri who had left Oculomotor palsy with sparing of the pupillary fibres, which resolved following treatment with oral acetazolamide.

Idiopathic intracranial hypertension (IIH) is the syndrome of raised intracranial pressure without clinical, laboratory or radiological evidence of intracranial pathology. IIH is a relatively rare disease but rapidly increasing incidence is reported due to a global increasing incidence of obesity. Disease course is generally said to be self-limiting within a few months. However, some patients experience a disabling condition of chronic severe headache and visual disturbances for years that limit their capacity to work. Permanent visual defects are serious and not infrequent complications. The pathophysiology of IIH is still not fully understood. Advances in neuroimaging techniques have facilitated the exclusion of associated conditions that may mimic IIH. No causal treatment is yet known for IIH and existing treatment is symptomatic and rarely sufficient. The aim of this review is to provide an updated overview of this potentially disabling disease which may show a future escalating incidence due to obesity. Theories of pathogenesis, diagnostic criteria and treatment strategies are discussed.

Primary headaches can be considered simultaneously as symptom and disease itself, while secondary headaches are expressions of a pathological process that can be systemic or locoregional. Because of its subjective features, headache is often difficult to assess and quantify by severity, frequency and invalidity rate, and for these reasons it has often been implicated in legal controversies. Headache has seldom been considered in the criminal law, except when it represents a typical symptom of a disease whose existence can be objectively assessed (i. e. raised intracranial pressure). Therefore, in civil legislation it is not yet coded to start claiming for invalidity compensation. In particular, one of the most debated medical-legal questions is represented by headaches occurring after head injury. Headache is often the principal symptom at the beginning of several toxic chronic syndromes, with many implications, especially in working claims, and, more recently, it may be referred to as one of the most frequent symptoms by victims of mobbing (i. e. psychological harassment in the workplace). The National Institute for Industrial Accident Insurance (INAIL) scales (instituted by the law 38/2000) mention the "Subjective cranial trauma syndrome" and give an invalidity rate evaluation. With reference to other headache forms, no legislation really exists at the present time, and headache is only considered as a symptom of a certain coded disease. Requests for invalidity social pension and the question of off-label prescriptions (drug prescription for a disease, without formal indication for it) are other controversial matters.
