Idiopathic intracranial hypertension presenting as iron deficiency anemia: a case report.

BACKGROUND: The presentation of idiopathic intracranial hypertension (IIH) in association with iron deficiency anemia (IDA) is rare. CASE PRESENTATION: This case report depicts the unusual case of a 31-year-old woman of mixed Jamaican and English heritage with IIH who presented initially as IDA in the context of menorrhagia. Subsequent ophthalmic review, lumbar puncture, cerebrospinal fluid analysis and neuroimaging studies revealed severe bilateral optic disc swelling and raised intracranial pressure in keeping with IIH. Prompt treatment of IDA with blood transfusion and orally administered iron supplements, in addition to medical treatment for IIH, contributed to significant improvement of symptoms and prevented long-term visual deficits. CONCLUSION: The possibility of IDA, albeit rare, should always be considered and investigated appropriately in all patients with IIH, as the treatment of the anemia alone may be sight-saving.

Short-term Optic Disc Cupping Reversal in a Patient With Mild Juvenile Open-angle Glaucoma Due to Early Idiopathic Intracranial Hypertension.

PURPOSE: The purpose of this study was to report a case of optic disc cupping reversal in an adult without significant intraocular pressure-lowering treatment. PATIENT: A 20-year-old female with a history of mild juvenile open-angle glaucoma who developed subjective blurred vision and a decrease in cupping of her optic discs. RESULTS: Dilated examination demonstrated decreased cup-to-disc ratios in both eyes with a slight blurring of the disc margin in the right eye. The appearance of both optic discs returned to baseline after weight loss therapy. CONCLUSIONS: An unexplained reduction of optic nerve cup-to-disc ratio should prompt a workup for other etiologies, such as increased intracranial pressure. Baseline photographs not subjected to computerized scan obsolescence are extremely useful in monitoring the long-term appearance of asymmetric optic discs as an adjunct to the clinical examination.

Hipertensión endocraneana idiopática: respuesta al tratamiento Topiramato vs Acetazolamida / Endocranial idiopathic hypertension: response to treatment Topiramate vs. Acetazolamide

INTRODUCCIÓN: El término pseudotumorcerebri se reserva para denominar aquellas hipertensiones endocraneanas (HE) que clínicamente asemejan la existencia de un tumor cerebral, debido a la alteración de la circulación del líquido cefalorraquídeo (LCR). Para su diagnóstico se describen los criterios de Dandy-Smith. OBJETIVOS: Objetivo Primario: Determinar el beneficio del uso de Azetazolamida (ACZ) o Topiramato (TPM) en el tratamiento de la hipertensión endocraneana idiopática. Objetivos Secundarios: Uso de Presión de apertura como parámetro indicador para uso de ACZ o TPM. MATERIALES Y MÉTODOS: Tipo de estudio: Descriptivo Retrospectivo Observacional. RESULTADOS: La media de seguimiento fue de 11 meses, con un rango entre 6-12 meses Se estudiaron 5 pacientes con diagnóstico de Hipertensión Endocraneana Idiopática. Del total de los pacientes 5 (100%) tenían F.O patológico y como síntoma cardinal cefalea, 2 (40%) además vómitos. 3 (60%) fue tratado con Topiramato (TPM) mientras que 2 (40%) recibió acetazolamida (ACZ), ambos sin complicaciones (p= 0,07) Del total de los pacientes 3(60%) presento presión de apertura menor de 40 mmHg mientras que en los restantes 2 (40%) fue mayor a 40 mmHg. De estos últimos el 1 paciente recibió TPM y 1 paciente ACZ. Dos pacientes (40%) presentaron en el seguimiento una recaída sintomática, al intentar descender la medicación. No se pudo definir como parámetro de decisión la presión de apertura en del uso de uno u otro medicamento ya que al evaluar el uso de TPM y ACZ en pacientes con presión de apertura mayor a 41 mmHg solo se detallaron 2 pacientes cada uno tratado con un medicamento de los anteriormente descriptos. (Chi cuadrado p= 0.44). Ninguno de los pacientes tratados requirió otro tratamiento complementario como PL seriadas o válvula de derivación ventrículo peritoneal. CONCLUSION: No se logró determinar beneficio en el uso de un medicamento sobre otro en el tratamiento de la hipertensión endocraneana idiopática (p=0,07), pese al tamaño muestral, el cual podría ser un limitante. Coincidentemente con la literatura sigue sin haber evidencia suficiente. No existe un algoritmo de consenso en cuanto al correcto manejo terapéutico y farmacológico de esta entidad. El uso de TPM o ACZ no condiciona la posterior aparición de complicaciones (p= 0.45) El estudio oftalmológico es esencial para diagnóstico y seguimiento. No se pudo establecer correlación entre el valor obtenido en la medición de la presión de apertura y el tratamiento instaurado. (AU)

INTRODUCTION: The term Pseudotumor cerebri is reserved for those endocranial hypertensio (EH) that resemble clinically the existence of a brain tumor, due to alteration of the circulation of the cerebrospinal fluid (CSF). Classically, the Dandy-Smith criteria for diagnosis are described. TYPE OF STUDY: Descriptive observational. OBJECTIVE: Primary Objective: To determine the benefit of the use of Azetazolamide (ACZ) or Topiramate (TPM) in the treatment of idiopathic endocranial hypertension Secondary Objectives: Use of Opening Pressure as indicator parameter for use of ACZ or TPM. MATERIALS AND METHODS: Observed patients(N:5) per clinic with diagnosis of EIH by criteria of Dandy-Smith in the period 2013-2017. I was performed in all patients: RMNC s/contrast Fundus oculi Lumbar puncture + opening pressure. RESULTS: Of the total of patients (5) 100% had F.O pathological and as cardinal symptom headache, and 40% also vomiting. The mean follow-up was 11 months 60% of the patients was treated with topiramate (TPM) while 40% received acetazolamide (ACZ), both without complications. Of the total of patients 60% presented less than 40 opening pressure mmHg, while that in the remaining 40% was greater than 40 mmHg, of which 50% received TPM and 50% ACZ. 40% presented in tracking a symptomatic relapse, trying to get off the medication. None of the treated patients required other adjunctive therapy such as serial PL or ventricleperitoneal shunt. CONCLUSIONS: It was not possible to determine benefit in the use of one drug over another in the treatment of idiopathic intracranial hypertension (p = 0.07), despite the sample size, which could be a limitation. Coincidentally with the literature there is still not enough evidence. There is no consensus algorithm regarding the correct therapeutic and pharmacological management of this entity. The use of TPM or ACZ does not condition the subsequent appearance of complications (p = 0.45) The ophthalmological study is essential for diagnosis and follow-up. No correlation could be established between the value obtained in the measurement of the opening ression and the treatment established. (AU)

Dronabinol reduces signs and symptoms of idiopathic intracranial hypertension: a case report.

A case is presented in which a woman diagnosed with a longstanding history of idiopathic intracranial hypertension reported improvement of frontal headaches, photophobia, transient blindness, enlarged blind spots, and tinnitus after smoking marijuana. All these symptoms and signs were associated with increased intracranial pressure (220-425 mm of water). Treatment with dronabinol at a dose of 10 mg twice a day, then reduced to 5 mg twice a day, relieved all of her symptoms. Previously noted papilledema and enlargement of blind spots also resolved, and this, in the absence of psychoactive effect or weight gain.

Benign intracranial hypertension in an older child with cystic fibrosis.

Despite having normal height and weight, a 6-year-old girl had frequent bowel movements and slight recurrent chest infections since the age of 4 years and headache for 1 year. The patient appeared healthy, but examination of the ocular fundus revealed papilledema. Cranial computed tomography appeared normal. Lumbar puncture disclosed an elevated opening cerebrospinal fluid pressure, with normal biochemical, cellular, and bacteriologic findings. Laboratory investigations indicated pathologic steatorrhea, elevated electrolytes in 3 sweat tests, and low serum levels of vitamins A and E. The diagnosis of pseudotumor cerebri in a patient with cystic fibrosis was made. After treatment with prednisone (1 mg/kg/day), pancreatic extracts, and vitamin supplements, headache and papilledema resolved and serum vitamin A and E levels subsequently became normal. Older children with cystic fibrosis rarely have benign intracranial hypertension, but when present it is often due to hypervitaminosis during correction of malnutrition. In this child, pseudotumor cerebri and associated hypovitaminosis improved after combined corticosteroid and vitamin treatment.
