BACKGROUND AND PURPOSE Ischemic stroke is the most common complication after surgical clipping of anterior choroidal artery (AChA) aneurysms, and the reported morbidity-mortality rates vary from 5% to 50%. We report the findings in a series of 18 consecutive patients who underwent endovascular treatment (EVT) for an AChA berry aneurysm. METHODS In this(More)
Sensorineural hearing loss and/or vertigo are rare but severe complications of stapes surgery for otosclerosis, ranging from 0.2 to 3%. Management of such complications depends on the underlying cause: intravestibular protrusion of the prosthesis, perilymph fistula, labyrinthitis, and reparative granuloma extending into the vestibule. Surgery is mandatory(More)
Our objective was to assess the value of delayed contrast-enhanced T1-weighted spin-echo MR imaging in the detection of residual cholesteatoma in patients who have undergone canal wall-up tympanoplasty procedure. The MR imaging was obtained prior to revision surgery in 18 patients with opacity of the post-operative cavity at CT examination 12–18 months(More)
The aim of this article is twofold: (a) to present the principles and the indications of surgical treatment of middle ear pathologies; and (b) to review the imaging findings after middle ear surgery, including the normal postoperative aspects and imaging findings in patients presenting with unsatisfactory surgical results or with suspicion of postoperative(More)
OBJECTIVES To present a series of temporal en plaque meningiomas involving the middle ear or mastoid, whose main symptoms suggested a serous otitis media. STUDY DESIGN AND SETTINGS Multicentric retrospective study reviewing clinical records originating from eight tertiary referral centers. MATERIALS AND METHODS The clinical records of 10 patients(More)
Patients with superior semicircular canal dehiscence (SSCD) may have conductive hearing loss (CHL) with normal middle ear (ME). A patient with CHL and normal tympanic membrane at otoscopy underwent tympanotomy for presumed otosclerosis but had negative intraoperative findings. A high-resolution computed tomography (CT) scan of the temporal bone performed a(More)
Superficial hemosiderosis of the central nervous system (SH-CNS) is a relatively rare condition caused by chronic or repeated subarachnoid bleeding. The aim of this article was to present hearing disorders related to SH-CNS, and to describe results of magnetic resonance imaging (MRI) to confirm the diagnosis. We performed a retrospective case review at a(More)
