ABSTRACT

Myiasis is the infestation of live vertebrates by dipterous larvae. Cutaneous myiasis is the most common form, although many organs can be infected by these larvae. Cutaneous myiasis is divided into 3 forms: localized furuncular, migratory, and wound myiasis, which have a worldwide distribution, but tropical and subtropical countries have a heavier burden of the disease. Herein, we report a case of scalp wound myiasis in a patient with pemphigus vulgaris caused by Muscidae domestica (M. domestica) in Riyadh, Saudi Arabia. Cases of M. domestica myiasis are limited in the literature. We would like to raise awareness regarding the possibility of cutaneous myiasis in M. domestica in Riyadh, Saudi Arabia.

ABSTRACT

INTRODUCTION: A narrow duplicated internal auditory canal (IAC) is an extremely rare anomaly, likely associated with congenital sensorineural hearing loss due to aplasia/hypoplasia of the vestibulocochlear nerve or the cochlear branch alone. We aimed to review our experience with IAC duplication, describe its clinical characteristics, and present a literature review. CASE PRESENTATION: Our Otology database was searched for children who showed duplication of the IAC. Clinical characteristics of two children with bilateral duplication of the IAC are described. Data regarding clinical history, auditory assessment, magnetic resonance imaging (MRI), and computed tomography (CT) were collected and analyzed. The separated, accessory bony canals were demonstrated on high-resolution CT scans, and the nerves were demonstrated on MRI. DISCUSSION: To date, a few cases of narrow duplicate IAC have been reported in the literature, Approximately 20% of patients with congenital SNHL are found to show inner-ear bony abnormalities on CT, but much uncertainty still exists about the mechanism underlying IAC stenosis.5 Imaging findings of the temporal bone in our case series demonstrated asymmetrical narrowing of both IACs, there is no clear evidence in the literature supporting the predominance of one side over the other. In our series, facial nerve function was intact bilaterally. As for our cases, both patients were enrolled in a single-sided deafness evaluation for a trial of options such as BAHA, CROS, cochlear implants, and other non-implantable hearing aids. Furthermore, addressing the important factors will optimize the outcomes including surgery at early age to optimize neural plasticity, with intense long-term therapy. CONCLUSION: Congenital duplication of the IAC likely convoying sensorineural hearing loss due to aplasia/hypoplasia of the vestibulocochlear nerve. Early diagnosis and intervention are essential to optimize patient outcomes.
