Prevalence of chronic rhinosinusitis in the general population based on sinus radiology and symptomatology.

Background: The prevalence of chronic rhinosinusitis (CRS) measured in epidemiologic studies is 5% to 12%. This might be an overestimation because of overlap with other diseases, such as allergic rhinitis.

Objective: We aimed to calculate the prevalence of CRS using a combination of epidemiologically based CRS according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) together with sinonasal opacification on imaging.

Chronic orbital inflammatory disease and optic neuropathy associated with long-term intranasal cocaine abuse: 2 cases and literature review.

Orbital inflammatory disease and secondary optic neuropathy is a rare but devastating complication of long-term intranasal cocaine abuse. We describe 2 patients with a history of intranasal cocaine consumption who presented with subacute onset of unilateral vision loss from optic neuropathy and limitation of abduction in the affected eye. Magnetic resonance imaging findings included an orbital mass in combination with absent nasal septum and partial destruction of the paranasal sinuses.

Computed tomography pulmonary angiography in acute pulmonary embolism: the effect of a computer-assisted detection prototype used as a concurrent reader.

Purpose: To assess the effect of computer-assisted detection (CAD) on diagnostic accuracy, reader confidence, and reading time when used as a concurrent reader for the detection of acute pulmonary embolism in computed tomography pulmonary angiography.

Materials And Methods: In this institutional review board-approved retrospective study, 6 observers with varying experience evaluated 158 negative and 38 positive consecutive computed tomography pulmonary angiographies (mean patient age 60 y; 115 women) without and with CAD as a concurrent reader. Readers were asked to determine the presence of pulmonary embolism, assess their diagnostic confidence using a 5-point scale, and document their reading time.

Endoscopic management of Ewing's sarcoma of ethmoid sinus within the AMORE framework: a new paradigm.

The Ablative surgery, MOulage brachytherapy and REconstruction) (AMORE) protocol developed in the Academic Medical Center of Amsterdam has been used successfully to treat sarcomas. The use of endoscopic surgery fits well within this framework. A 6-year-old boy presented with Ewing Sarcoma of left ethmoid sinus closest to orbit.

Predictors of endoscopic transsphenoidal surgery outcome in acromegaly: patient and tumor characteristics evaluated by magnetic resonance imaging.

The availability of various first-line treatment modalities for acromegaly and evolving surgical techniques emphasize the need for accurately defined predictors of surgical outcome. We retrospectively analysed the outcome of 30 patients with acromegaly after initial endoscopic transsphenoidal surgery in two university hospitals from 2001 until 2009, and reviewed comparable literature investigating predictive tumor characteristics. Medical records were monitored for patient characteristics.

Imaging findings in craniofacial childhood rhabdomyosarcoma.

Rhabdomyosarcoma (RMS) is the commonest paediatric soft-tissue sarcoma constituting 3-5% of all malignancies in childhood. RMS has a predilection for the head and neck area and tumours in this location account for 40% of all childhood RMS cases. In this review we address the clinical and imaging presentations of craniofacial RMS, discuss the most appropriate imaging techniques, present characteristic imaging features and offer an overview of differential diagnostic considerations.
