OBJECTIVES: Idiopathic intracranial hypertension (IIH) is a syndrome that excludes secondary causes such as intracranial space-occupying lesion, hydrocephalus, cerebrovascular disease, and hypoxic ischemic encephalopathy. If not be treated promptly and effectively, IIH can cause severe, permanent vision disability and intractable, disabling headache. This study aims to explore the clinical and image features for IIH, to help clinicians to understand this disease, increase the diagnose rate, and improve the outcomes of patients. METHODS: We retrospectively analyzed 15 cases of IIH that were admitted to Xiangya Hospital, Central South University, during January 2015 to September 2020. The diagnosis of IIH was based on the updated modified Dandy criteria. We analyzed clinical data of patients and did statistical analysis, including age, gender, height, weight, medical history, physical examination, auxiliary examination, treatment and outcome. RESULTS: There were 10 females and 5 males. Female patients were 22 to 42 years old with median age of 39.5. Male patients were 27 to 52 years old with the median age of 44.0. The BMI was 24.14-34.17 (28.71±2.97) kg/m CONCLUSIONS IIH primarily affects women of childbearing age who are overweight. The major hazard of IIH is the severe and permanent visual loss. Typical image signs have high specificity in IIH diagnosis. Prompt diagnosis and effective treatment are significantly important to improve the outcomes of patients.

Idiopathic intracranial hypertension,also known as pseudotumor cerebri,is a syndrome characterized by raised intracranial pressure of unknown cause.These patients present normal neuroimaging and cerebrospinal fluid analysis while increased intracranial pressure and associated symptoms and signs.Delay of treatment can cause severe visual impairment.There are some new understandings of this disease,and we will review the pathogenesis,diagnosis,and treatment of idiopathic intracranial hypertension.

For many years, the pathophysiology of idiopathic intracranial hypertension (IIH) was interpreted as “secondary intracranial hypertension,” and IIH was considered to be caused by brain edema due to obstructive sleep apnea. Another theory proposed cerebrospinal fluid (CSF) absorption impairment due to excessive medication with vitamin A derivatives. Other reports pointed out the importance of obesity, which may cause an impairment of intracranial venous drainage due to elevated right atrial pressure. Patients with medically refractory IIH have traditionally undergone a CSF diversion. Venous outlet impairment on IIH has recently been reported as a causative or contributory cause, and thus focused venoplasty of the stenotic sinus with a stent has emerged as a new treatment strategy. We report the cases of two patients who presented with headache and papilledema with IIH. They successfully underwent stent placement at the stenosis of the transverse sinus and experienced complete resolution of symptoms.

PURPOSE: To report cases of a retinal, preretinal and vitreous hemorrhage due to retinoic acid syndrome and a papilledema caused by increased intracranial pressure in patients with acute promyelocytic leukemia treated with all-trans retinoic acid (ATRA). CASE SUMMARY: (Case 1) A 48-year-old female visited our clinic with headache, dyspnea, and visual disturbance during ATRA medications for acute promyelocytic leukemia. Her visual acuity of both eyes was hand motion, and fundus examination revealed extensive retinal, preretinal, and vitreous hemorrhage. The laboratory test showed leukocytosis and computed tomography of brain and chest revealed subarachnoid hemorrhage and pulmonary alveolar hemorrhage. She was diagnosed with retinoic acid syndrome and was treated with vitrectomy in both eyes. (Case 2) A 17-year-old male, who had been treated with ATRA for acute promyelocytic leukemia, had headache and visual disturbance. His best-corrected visual acuity was 1.0 in both eyes, but the fundus examination showed papilledema and retinal hemorrhage in both eyes. Goldmann visual field examination revealed an enlarged blind spot in both eyes. He was diagnosed with papilledema caused by ATRA induced increased intracranial pressure, and was observed. CONCLUSIONS: Patients with acute promyelocytic leukemia treated with ATRA may have retinoic acid syndrome and increased intracranial pressure that could result in retinal hemorrhage, vitreous hemorrhage, and papilledema.

Giant arachnoid granulations have been reported to be associated with headaches, which can be acute or chronic in presentation. In some cases, idiopathic intracranial hypertension, previously called pseudotumor cerebri, may occur. The pathophysiology of these enlarged structures seen as filling defects on imaging is not clearly defined, although they are presumed to cause symptoms such as headache via pressure resulting from secondary venous sinus obstruction. We present a unique presentation of secondary headache in a 39-year-old man with no prior history of headaches found to have giant arachnoid granulations, presenting as migraine with aura.

Pupil-involving oculomotor nerve palsy (ONP) is frequently associated with compressive lesion such as intracranial aneurysm originating from the posterior communicating arteries. Vascular variant of posterior intracranial circulation is regarded as an uncommon cause and association between these vascular variants and intracranial hypertension has not been reported. We present an 18-year-old girl with pupil-involving ONP combined with idiopathic intracranial hypertension who revealed compression of oculomotor nerve by a vascular variant of superior cerebellar artery (SCA). This is a rare case of an ONP attributed to compressive effect from an aberrant SCA affected by intracranial hypertension.

Inflammatory pseudotumors, which clinically mimic neoplasms, are space-occupying collections of inflammatory cells, histiocytes, and fibroblasts. They are most often found in the orbits and lungs, but rarely in the head and neck region, and hardly ever in the nasal septum. Here we report on a 71-year-old woman with pseudotumor cerebri and an inflammatory pseudotumor of the nasal septum. This case demonstrates that inflammatory pseudotumor can cooccur in the brain and nasal septum.
