Acute sphenoid sinusitis leading to contralateral cavernous sinus thrombosis: a case report.
The objective of this article was to report a case of isolated, acute, right-sided sphenoid sinusitis that progressed to contralateral cavernous sinus thrombosis in an 18-year-old male patient. We describe the atypical presentation of this case and discuss the relevant anatomy, pathogenesis, presentation, diagnostic evaluation and treatment. ⋯ Cavernous sinus thrombosis is a rare clinical entity in the antibiotic era. However, limited sphenoid sinusitis may progress to cavernous sinus thrombosis in spite of maximal medical treatment, as highlighted in this case report. The mainstay of treatment includes early diagnosis allowing aggressive intravenous antibiotics and appropriate surgical management.

The search for a primary malignancy in patients with a metastatic cervical lymph node is challenging yet ultimately of utmost clinical importance. This study evaluated the efficacy of positron emission tomography computed tomography in detecting the occult primary, within the context of a tertiary referral centre head and neck cancer multidisciplinary team tumour board meeting. ⋯ Positron emission tomography computed tomography has become an important imaging modality. To date, it has the highest primary tumour detection rate, for head and neck cancer patients presenting with cervical lymph node metastases from an unknown primary.

YouTube is an internet-based repository of user-generated content. This study aimed to determine whether YouTube represented a valid and reliable patient information resource for the lay person on the topic of rhinosinusitis. ⋯ YouTube appears to be an unreliable resource for accurate and up to date medical information relating to rhinosinusitis. However, it may provide some useful information if mechanisms existed to direct lay people to verifiable and credible sources.
