Aneurysmal bone cysts (ABCs) arising from vascular malformation are extremely rare, and none have been reported in the literature in English till now. We report a very rare case of secondary ABC of left temporal bone in a 5-year-old Caucasian boy who presented with a left sudden facial palsy associated with a painless non-tender mass of the left temporo-parietal region. The computed tomography (CT) and magnetic resonance imaging (MRI) features were suggestive of ABC secondary to a capillary venous malformation, with concurrent involvement of the squamous, mastoid, and petrous portions of the temporal bone. Surgical resection was performed. On follow-up, the patient was found to be doing well.

Introduction: Tuberculous otomastoiditis is a rare and serious infection that most often occurs in association with pulmonary involvement. It is easy to diagnose when the two pathologies are associated and isolated. We herein report the case of a patient initially hospitalized for Pseudomonas aeruginosa necrotising otitis externa (NOE), which delayed the diagnosis of tuberculous otomastoiditis.

Objective: This study aims to present a case of temporal bone (TBP) paraganglioma with an insidious clinical presentation, deviating significantly from the typical hearing loss and pulsatile tinnitus pattern.
Methods: A 70-year-old lady presented to the emergency department with a five-day history of right progressive later cervical swelling extending to the mastoid region and chronic worsening purulent otorrhea. The clinical and radiological findings confirmed the presence of a chronic middle ear process complicated by a Bezold abscess.
Deciphering compromised speech-in-noise intelligibility in older listeners: the role of cochlear synaptopathy.

Speech intelligibility declines with age and sensorineural hearing damage (SNHL). However, it remains unclear whether cochlear synaptopathy (CS), a recently discovered form of SNHL, significantly contributes to this issue. CS refers to damaged auditory-nerve synapses that innervate the inner hair cells and there is currently no go-to diagnostic test available.
