Osteomas of the internal auditory canal are rare lesions, with only 12 reported cases in the world literature. Symptoms are those of eighth nerve compression, and include unilateral hearing loss and vestibular weakness, thus mimicking symptoms of acoustic neuroma. We report a patient with an osteoma of the internal auditory canal, along with a review of the literature. We note age and sex characteristics from the literature, give evidence of localized trauma as a possible etiologic factor for this lesion, and discuss the pitfalls of relying exclusively on magnetic resonance imaging in the workup of suspected retrocochlear lesions.

AbstractA 42-year-old man with normal hearing presented with a long history of vertigo and tinnitus. CT scan showed large osteomata of the internal auditory canal. Magnetic resonance imaging (MRI) was normal. The osteomata were removed surgically via the retrosigmoid approach and examined histologically. His symptoms were abolished. As MRI has become the gold standard in the search for small acoustic tumours it is likely that symptomatic bony lesions, rare though they are, will be missed if MRI is the sole imaging modality. A review of the literature is included.

AbstractObjective:We describe a rare case of an ectopic submandibular gland associated with atrophy of the ipsilateral floor of the mouth muscles.Method:Case report and review of the world literature regarding ectopic submandibular glands.Results:The reported patient had an ectopic submandibular gland associated with atrophy of the ipsilateral anterior digastric and mylohyoid muscles. This implies maldevelopment of these muscles in the floor of the mouth and arrest of the normal migration of the submandibular gland. The condition was diagnosed using magnetic resonance imaging and conventional submandibular gland sialography.Conclusion:Submandibular gland ectopia in the floor of the mouth is a rare phenomenon. The described case represents the first report of an ectopic submandibular gland associated with atrophy of the ipsilateral floor of the mouth muscles. Radiologists and clinicians should familiarise themselves with this entity and its imaging findings, in order to prevent unnecessary biopsy of this benign condition.

AbstractOsteoid osteoma is a benign osteoblastic tumor, quite uncommon in the spine. We report a case of an osteoid osteoma involving the atlas in a 6-year-old boy, who presented with suboccipital pain and torticollis. Initial radiological findings were ambiguous as magnetic resonance imaging showed mainly edema of upper cervical soft tissues. The subsequent computed tomography depicted a lesion of left lamina of C1. As conservative treatment failed, the lesion was surgically resected and the patient became pain free. To our knowledge, this is the first case of osteoid osteoma involving the atlas associated with abnormal soft tissue reaction reported in literature.

AbstractObjectives:We report a case of otogenic fungal pachymeningitis in a diabetic patient who presented with multiple cranial nerve palsies and nasopharyngeal swelling.Methods:We present a case report, we describe the investigations, management and clinical course of fungal pachymeningitis, and we present a review of the world literature on fungal and non-fungal pachymeningitis.Results:To our knowledge, this is the first report of fungal pachymeningitis with magnetic resonance imaging features suggestive of nasopharyngeal carcinoma. It is also the first reported case with aspergillus cultured from both a dural biopsy and the ear canal.Conclusion:Fungal pachymeningitis is a rare condition which may present to otorhinolaryngologists. Its clinical and radiological findings can be confused with those of nasopharyngeal carcinoma; fungal pachymeningitis should thus be included in the differential diagnosis of nasopharyngeal carcinoma.

AbstractNorovirus is a common cause of acute gastroenteritis outbreaks worldwide. The disease can present with varying degrees of neurologic impairment from benign convulsions to rare cases of severe encephalopathy. We describe a case report of a North American infant who presented with norovirus gastroenteritis, status epilepticus, severe encephalopathy, and abnormal but reversible diffusion restriction changes on magnetic resonance imaging of brain.
