Purpose: The frequency and patterns of HL in a HNRMS survivor cohort were investigated. A dose-effect relationship between the dose to the cochlea and HL was explored.
Methods: Dutch survivors treated for HNRMS between 1993 and 2017 with no relapse and at least two years after the end of treatment were eligible for inclusion.
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.
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.

The advantages of functional MR imaging techniques such as diffusion weighted imaging (DWI) and dynamic contrast-enhanced MR imaging (DCEMRI) in comparison with traditional MRI will be outlined. The limited role of (18)FDG-PET CT and fMRI will be addressed.

Therefore, new local treatment modalities, such as brachytherapy, have been developed to minimize adverse events. Since 1990, patients with orbital RMS and a residual tumor after induction chemotherapy were eligible for resection and brachytherapy.

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.
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.

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.

Methods: The 140 CXRs (56 with a solitary CT-proven nodules and 84 negative controls) were divided into four subsets of 35; each were read in a different order by six readers. Lesion presence, location and diagnostic confidence were scored without and with CAD (IQQA-Chest, EDDA Technology) as second reader.
Rationale And Objectives: To evaluate the impact of computer-aided detection (CAD, IQQA-Chest; EDDA Technology, Princeton Junction, NJ) used as second reader on the detection of small pulmonary nodules in chest radiography (CXR).
Materials And Methods: A total of 113 patients (mean age 62 years) with CT and CXR within 6 weeks were selected. Fifty-nine patients showed 101 pulmonary nodules (diameter 5-15mm); the remaining 54 patients served as negative controls.
Aim: To evaluate the outcome of surgery and radiotherapy in the treatment of sphenoorbital meningioma (SOM).
Method: A retrospective study of 66 consecutive cases treated with surgery for SOM with a minimum follow-up of 4 years. Clinical and radiological information were compared before and after the following surgical approaches: frontotemporal craniotomy, frontotemporal craniotomy combined with orbitozygomatic resection and extended lateral orbitotomy alone.
Background: To investigate the natural history and the growth rate of spheno-orbital meningiomas (SOMs).
Methods: Ninety patients with a diagnosis of SOM were included, and patient charts and imaging were evaluated. In a subset of 32 patients, volumetric studies were performed.
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.

Our specifically developed approach consists of applying brachytherapy to the tumor area using a mold. Analysis of its results for 20 patients was performed.

The purpose of this retrospective study was to assess the predictive value of the diagnosis of deep neck abscess using CECT.
Study Design: Retrospective chart review study over a 5-year period from 2002 to 2007 by a blinded observer.
Objective: To investigate the value of somatostatin receptor scintigraphy (SSRS) in the diagnosis of optic nerve sheath meningiomas (ONSMs).
Design: Prospective, comparative case series.
Participants: SSRS was used to investigate 68 orbits in 61 patients diagnosed with an orbital tumor.
Purpose: A multidisciplinary approach, consisting of consecutive Ablative Surgery, MOld technique with afterloading brachytherapy and immediate surgical REconstruction (AMORE) applied after chemotherapy, was designed for children with rhabdomyosarcoma in the head-and-neck region. Analysis of the first 42 patients was performed.
Methods And Materials: After macroscopically radical tumor resection, molds were constructed for each individual to fit into the surgical defect.
Objective: The optimal positioning of electrode arrays in the cochlea is extremely important. Our standard approach is to use a 3-dimensional rotational x-ray for the intraoperative determination of the position of the electrode array. We wanted to see if spread of excitation (SOE) is useful for determining the electrode array position within the cochlea.

Object: Multislice computed tomography (CT) angiography may be useful for screening patients with intracranial aneurysms that are treated with clip occlusion. However, cobalt clips produce much more artifact on CT scans than titanium clips, which may hamper the evaluation of the image obtained at the clip site.
Methods: The authors screened 415 patients with previously ruptured aneurysms that had been treated using cobalt clips.
Background: The AMORE protocol is a local treatment for patients with nonorbital pediatric head and neck rhabdomyosarcoma (HNRMS). The objectives of this study were: (1) to assess the adequacy of the concept, and (2) to identify factors associated with relapse.
Methods: We performed a retrospective multidisciplinary review of 22 children primarily treated according to the AMORE protocol, excluding two children with inadequate imaging data.
