AbstractBackgroundDislocation of the cochlear implant magnet is an uncommon but recognised complication of magnetic resonance imaging in a patient with a cochlear implant.Case reportThis paper reports a case of cochlear implant magnet dislocation despite head bandaging. The patient subsequently underwent endoscopic repositioning of the magnet under general anaesthesia. The cochlear implant system was tested intra-operatively and confirmed to be functioning. The patient was well at follow up and the small wound healed well with no complications.ConclusionThis report presents the endoscopic technique as a viable minimally invasive surgical approach to address cochlear implant magnet dislocation.

Chondroblastoma located in the talus is a rare incidence, and due to the weightbearing duty of the talus, the results of local excision may not be favorable. While the volume of the tumor increases, more sophisticated techniques may be undertaken. Cell-free matrix application for extensive osteochondral defects is gaining popularity for its structural support when it is used with microfracture and autograft application. In this case report, we present a patient with 13 × 20 × 8mm–sized chondroblastoma located in the talus. After evaluation of the mass, we performed curettage, iliac crest autograft application, and augmentation with cell-free matrix. After uneventful clinical follow up, we present our patient's postoperative second year magnetic resonance imaging and functional status.

Secondary paroxysmal dyskinesias (SPDs) are short, episodic, and recurrent movement disorders, classically related to multiple sclerosis (MS). Carbamazepine is effective, but with risk of adverse reactions. We identified 7 patients with SPD among 457 MS patients (1.53%). SPD occurred in face ( n = 1), leg ( n = 2), or arm +leg ( n = 4) several times during the day. Magnetic resonance imaging (MRI) showed new or enhancing lesions in thalamus ( n = 1), mesencephalic tegmentum ( n = 1), and cerebellar peduncles ( n = 5). Patients were treated with clonazepam and then acetazolamide ( n = 1), acetazolamide ( n = 5), or levetiracetam ( n = 1) with response within hours (acetazolamide) to days (levetiracetam). No recurrences or adverse events were reported after a median follow-up of 33 months.

Magnetic resonance imaging–guided laser-induced thermal therapy (MRgLITT) is a minimally invasive surgical approach increasingly employed for precise targeted ablation of epileptogenic brain foci. Recent reports have described corpus callosotomy using MRgLITT, though its application in more extensive functional disconnections has not been documented. Here, the authors detail its use in achieving a palliative hemispherotomy in a 5-year-old with medically refractory hemiclonic seizures following a hemispheric infarction, highlighting a novel use of this surgical technique. In this particular case, open craniotomy was deemed high risk given the multiple medical comorbidities including congenital cardiac disease and end-stage renal failure. MRgLITT was considered an alternative approach with a lower risk for periprocedural hemodynamic perturbations. The patient tolerated the procedure well, attaining an Engel class IB outcome at 16 months’ follow-up. This suggests that MRgLITT may be an alternative approach to an open hemispherectomy, particularly in cases in which multiple comorbidities pose significant risks and preclude an open procedure.
