Pseudotumor cerebri (PTC) is characterized by intracranial hypertension without ventriculomegaly, in the absence of a mass lesion or meningeal process. When there is no secondary cause, it is termed 'idiopathic intracranial hypertension'. Headache is the most common symptom of PTC, present in over 90% of patients. The headache is often disabling and nonspecific in character; thus, ophthalmoscopy is imperative for all patients being evaluated for headache. Visual loss is the major morbidity of PTC, requiring prompt diagnosis and treatment to prevent permanent deficits. Medical and surgical treatments are employed, although evidence-based treatment guidelines do not exist. This review discusses the diagnosis, differential diagnosis and management strategies for patients with PTC.

Pseudotumor cerebri is a syndrome with headaches and visual loss that sometimes cannot be treated with medication. In spite of medical treatment, the clinical course in some patients can approach extreme dysfunction with severe impairment in visual field and acuity as well as incapacitating headache. Patients with progressive or persistent symptoms require surgical treatment and decompression of the optic nerve is the preferred surgical procedure. We report on two cases of bilateral decompression of the optic nerves performed through an endonasal endoscopic approach.

Cluster headache (CH) is a well-defined primary headache syndrome, but cases of symptomatic headache with clinical features of CH have been previously reported. Idiopathic Intracranial Hypertension (IIH) is a secondary headache disorder characterized by headache and visual symptoms, without clinical, radiological or laboratory evidence of intracranial pathology. Both papilloedema and IIH-related headache are typically bilateral, however asymmetrical or even unilateral localizations are described in literature. We report the case of a previously headache-free woman who presented cluster-like headache and asymmetrical papilloedema related to IIH. In our opinion the asymmetrical presentation supports, in this case, the hypothesis of cavernous sinus involvement in the IIH-related cluster-like headache pathogenesis.

Pseudotumor cerebri is a clinical condition marked by papilledema, normal cerebrospinal fluid composition, normal or small ventricles on radiography, and absence of an intracranial mass. In this condition, headache, tinnitus, dizziness, blurred vision, and diplopia are frequently observed. The cause is often unknown but can occur with certain drug ingestions or systemic inflammatory and metabolic diseases. The treatment is primarily focused on the correction of the underlying cause with measures to reduce the raised intracranial pressure. The most important complication is optic atrophy, which results in visual loss. The sixth cranial nerve is most commonly affected. The involvement of the third cranial nerve is distinctly unusual. The present report describes a unique case of bilateral oculomotor palsy with sparing of the papillary fibers. It resolved promptly on administration of acetazolamide.

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a disorder of elevated intracranial pressure of unknown cause. Patients present with daily headache, pulse-synchronous tinnitus, transient visual obscurations, papilledema with its associated visual loss, and diplopia from sixth nerve paresis. Many disease associations have been alleged, but few besides obesity, hypervitaminosis A and related compounds, steroid withdrawal, and female gender have been proven. Although absorption of cerebrospinal fluid (CSF) occurs through arachnoid granulations and extracranial lymphatics, outflow resistance is increased in IIH; therefore, intracranial pressure must increase for CSF to be absorbed. The mainstays of medical treatment are a reduced-sodium weight-reduction program and acetazolamide. If patients fail medical therapy, surgical procedures, most commonly optic nerve sheath fenestration and CSF shunting, are employed. The main morbidity of IIH is visual loss. This is present in most patients and can usually be reversed if recognized early in the course of the disease and treated.

Pseudotumor cerebri occurs quite rarely in the pediatric population and its clinical features differ from adults in many ways. Intracranial hypertension with papilledema should obviously be treated promptly to avoid permanent visual damage, but various more or less invasive options have been proposed over the years, from bariatric surgery for obesity to optic nerve sheath fenestration. We report a prospective study on a group of 15 children, aged 3-16 years, with clinical and instrumental diagnosis of pseudotumor cerebri. All the patients were treated simply by external lumbar cerebrospinal fluid drainage with a mean volume of 10 ml/h for 3-5 days, with hypocaloric diet and with appropriate dosages of acetazolamide. All had immediate relief of headache, a considerable reduction in papilledema and marked improvement of both visual loss and cranial nerve palsies within 2 months. None of the patients relapsed during the follow-up period, ranging from 12-48 months.

Idiopathic intracranial hypertension remains a disease of unknown etiology. Epidemiology, associations, features, and prognosis in children have changed over the years. The main clinical complaint of pediatric idiopathic intracranial hypertension is headache with visual disturbance. We report on a patient with childhood idiopathic intracranial hypertension, who presented without headache after hemodialysis for acute renal failure. Idiopathic intracranial hypertension without headache is believed to have a poor prognosis. However, this child demonstrated a favorable outcome with medical therapy. The child was followed with serial optical coherence tomography of retinal nerve fiber layer thickness around the optic nerve head. In the absence of a reliable procedure to evaluate the therapeutic efficacy in the follow-up of patients with idiopathic intracranial hypertension, the importance of optical coherence tomography, a noninvasive, objective, and reproducible procedure, is highlighted as a useful adjunct in the management of idiopathic intracranial hypertension.

We present three cases of rare side effects which appeared to be attributable to antibacterial drug treatment. A 57-year-old female patient was admitted to hospital due to increasing dyspnea. Computed tomography revealed interstitial lung fibrosis which was attributed to the toxic effects of nitrofurantoin (50 mg/d) that the patient used for approximately one year for recurrent urinary tract infection. She died two weeks after hospital admission due to acute respiratory failure. A 20-year-old male patient presented with most intense headache and psychomotor deceleration. Pseudotumor cerebri, which was suspected to be the underlying cause, is described as a rare side effect of minocyclin which the patient has taken for acne pustulosa (100 mg single dose). After dechallenge of minocyclin, neurological symptoms quickly subsided. A 82-year-old female patient used moxifloxacin (400 mg/d) for febrile bronchopulmonary infection for one week. During this therapy, confusion and severe dementia presented and remained for more than two months after discontinuation. The demential syndrome appears to be possibly related to the fluoroquinolone use. In summary, adverse drug effects not pertaining to the primary physician's field are especially difficult to identify. Most importantly, rare side effects must be borne in mind by the prescribing physician.

Idiopathic intracranial hypertension is a rare disorder characterized by elevated intracranial pressure without hydrocephaly or intracranial process. Its mechanism is poorly understood. Most cases of benign intracranial hypertension are presumed to be idiopathic but some of them may be related to some treatment. We report a 26-year-old female with benign intracranial hypertension due to tetracycline, revealed by headaches and gradual visual loss. Standard investigations were unremarkable and favourable outcome after therapeutic lumbar puncture confirmed the diagnosis.

Idiopathic intracranial hypertension (IIH) is defined as increased intracranial pressure in the absence of intracranial mass or obstructive hydrocephalus. Over 80% of patients are overweight women. IIH is usually encountered in the neurology and ophthalmology practise as headaches, visual disturbance and papilloedema are the characteristic features of this syndrome. Patients with IIH also experience tinnitus, hearing loss, balance disturbance, cerebrospinal fluid (CSF) otorrhoea or rhinorrhoea and in some cases these otorhinological symptoms can be presenting features of this syndrome. IIH is also associated with obstructive sleep apnoea. Otolaryngologists should be familiar with this important condition as it can manifest a variety of symptoms that are more frequently seen in their clinics. Sometimes otolaryngologists may be involved in the surgical management of this condition, such as repair of CSF rhinorrhoea or otorrhoea or endoscopic optic nerve decompression. The aim of this review article is to familiarise the otolaryngologists with the important features of this unusual syndrome which may remain unrecognised in the otolaryngology practice.
