Idiopathic intracranial hypertension (IIH) is the persistent increase in intracranial pressure in the absence of any intracranial lesions. Though termed idiopathic IIH is known to be associated with a wide variety of disease conditions and drugs i.e. SLE, adrenal insufficiency, Cushing disease, hypoparathyroidism, hypothyroidism, iron deficiency, vitamin A, tetracycline, nalidixic acid, steroid withdrawal and many others. IIH is a rare disease, but IIH developing after replacement of levothyroxine is even rarer. Only a handful of cases of IIH associated with levothyroxine therapy have been mentioned in the literature. We are reporting a case of IIH developing after starting levothyroxine replacement and then the literature is reviewed. DOI: 10.3329/jbsp.v29i1.7173J Bangladesh Coll Phys Surg 2011; 29:49-51

Abstract 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.

Background: Intracranial pressure (ICP) monitoring has been variously explored as a diagnostic and therapeutic modality in many pathological conditions leading neurological injury. This monitoring standardly depends on an invasive procedure such as cranial or lumbar catheterization. The gold standard for ICP monitoring is through an intraventricular catheter, but this invasive technique is associated with certain risks such as haemorrhage and infection. (1) Also, it is a high-cost procedure and consequently not available in a variety of underprivileged places and clinical situations in which intracranial hypertension is prevalent (3). An accurate non-invasive and low-priced method to measure elevated ICP would therefore be desirable. Under these circumstances, Brazilian scientists developed a non-invasive method for intracranial pressure monitoring (ICP-NI), which uses an electric resistance extensometer that measures micro deformations of the skull and transforms it into an electrical signal. In this case report, the authors describe a pediatrician patient with the diagnosis of idiopathic intracranial hypertension who was successfully submitted to a lumbar puncture under monitorization with this device. Case description: 7 year old girl with progressive symptoms that lead to the diagnosis of idiopathic intracranial hypertension. The patient was submitted to a lumbar punction with continuous non-invasive ICP monitoring. Conclusion: Estimating ICP (non-invasive) from LP monitoring (invasive) often reflect inaccurate ICP results, and affects negatively on IIH diagnosis and a non-invasive diagnostic method could reduce the requirement for invasive approaches, improving patient health outcomes.

Abstract Background Idiopathic intracranial hypertension (IIH) is a disorder of increased intracranial pressure without a clear cause and can have serious visual effects. Previous research work suggests that transcranial Doppler measurements of pulsatility index correlate accurately with elevated intracranial pressure. Objective To assess the cerebrovascular hemodynamic changes in patients with IIH using transcranial Doppler before and after lumbar puncture and CSF withdrawal. Methods An interventional study conducted on 40 patients (31 females and 9 males) fulfilling the modified Dandy criteria for diagnosis of idiopathic intracranial hypertension, MRI brain, and MRV was done to the patients. Lumbar puncture was done for all included patients to measure intracranial pressure and CSF withdrawal. Transcranial Doppler was performed for all included before and after lumbar puncture and CSF withdrawal and the following parameters were measured: peak systolic velocity (PSV), end diastolic velocity (EDV), resistivity index (RI), and pulsatility index (PI). Results Significant relation was found between grades of papilledema and PSV, RI, and PI (p value 0.012, 0.025, 0.016) but no significant relation was found between grades of papilledema and EDV (0.102). Significant changes occurred in parameters of TCD pre- and post-CSF withdrawal including PSV, EDV, and PI (p value 0.001, 0.015, 0.019) denoting a significant change in cerebral hemodynamics after CSF withdrawal which denotes a decrease in intracranial pressure. Conclusion Increased intracranial pressure significantly affects cerebral blood flow. A normalization of transcranial Doppler parameters occurs following lowering of intracranial pressure through lumbar puncture and CSF withdrawal.

Acute Retroviral Syndrome

We describe a 61-year-old man living with HIV on antiretroviral therapy (ART), who presented with headache, dizziness and blurred vision. Latest CD4+ cell count 3 months prior to admission was 570×106 cells/mL and HIV viral load <20 copies/mL. The patient was diagnosed with cerebrospinal fluid (CSF) lymphocytic pleocytosis, raised intracranial pressure and papilloedema. Neuroimaging showed normal ventricular volume and no mass lesions, suggesting (1) neuroinfection (2) idiopathic intracranial hypertension or (3) retroviral rebound syndrome (RRS) as possible causes. Neuroinfection was ruled out and idiopathic intracranial hypertension seemed unlikely. Elevated plasma HIV RNA level was detected consistent with reduced ART adherence prior to admission. RRS is a virological rebound after ART interruption, which can mimic the acute retroviral syndrome of acute primary infection. To the best of our knowledge, we describe the second case of RRS presenting as CSF lymphocytic pleocytosis and elevated intracranial pressure after low ART adherence.
