Diagnostic performance of ultrasound vs. ultrasound-guided FNAc in thyroid nodules: data from the ElaTION trial.

Introduction: ElaTION is a large multi-centre pragmatic randomised controlled trial, performed in 18 secondary/tertiary hospitals across England, comparing elastography ultrasound-guided fine needle aspiration cytology (EUS-FNAC) with ultrasound-guided FNAC (US-FNAC) alone in the diagnostic assessment of thyroid nodules. Secondary trial outcomes, reported here, assessed the accuracy of ultrasound-alone (US) compared with US-guided FNAC to inform and update current practice guidelines.

Methods: Adults with single or multiple thyroid nodules who had not undergone previous FNAC were eligible.

A Systematic Review and Meta-Analysis of 29 Studies Predicting Diagnostic Accuracy of CT, MRI, PET, and USG in Detecting Extracapsular Spread in Head and Neck Cancers.

Background: Extracapsular spread (ECS) is the extension of cancer cells beyond the lymph node capsule and is a significant prognostic factor in head and neck cancers. This meta-analysis compared the diagnostic accuracy of CT, MRI, PET, and USG in detecting ECS in head and neck cancers.

Methodology: The authors conducted a systematic review and meta-analysis of studies that compared the diagnostic accuracy of CT, MRI, PET, and USG in detecting ECS in head and neck cancers.

Incidence of synchronous contralateral tonsillar malignancy in a known case of unilateral tonsillar carcinoma.

Objective: The literature is divided with regards to contralateral tonsillectomy in a known/suspected case of ipsilateral tonsillar malignancy. In this study, we evaluate the incidence of indolent synchronous contralateral tonsillar malignancy (SCTC) in patients with known ipsilateral tonsillar malignancy.

Methods: All patients diagnosed with ipsilateral tonsillar carcinoma (TC) at a tertiary teaching center between January 2016 and December 2019 were screened.

Squamous carcinoma ex pleomorphic adenoma of the lacrimal gland.

We present a very rare case of squamous cell carcinoma (SCC) ex pleomorphic adenoma of the lacrimal gland. Our patient presented with a 12 month history of painful proptosis of his left eye associated with severe headache. Imaging showed a left lacrimal gland lesion with extensive orbital disease extending into lateral and superior rectus muscles, cavernous sinus and the greater wing of the sphenoid.

Inflammation of the Temporal Bone.

Temporal bone and ear structure inflammation is commonly due to infection. It can be associated with a variety of complications and postinflammatory sequelae. Where the ear is easily inspected, clinical evaluation suffices.

Actinomycosis of tongue: Rare presentation mimicking malignancy with literature review and imaging features.

Actinomycosis of the tongue is rare. It may be difficult to differentiate this infection clinically and radiologically from other tongue pathology especially neoplasia. We report a substantial tongue lesion which mimicked malignancy at presentation.

A case and literature review of orbital microcystic adnexal carcinoma.

Microcystic adnexal carcinoma (MAC) is a very rare and locally aggressive sweat gland tumour. MAC has been well reported presenting as a periocular cutaneous lesion, rarely with subsequent direct orbital invasion and only once as a primary orbital lesion. Local recurrence is frequent after primary surgical excision and the role of adjuvant radiotherapy is ill-defined.

A new cause of lacrimal gland calcification: Retained metallic foreign bodies.

A 49-year-old male presented with a 4 month history of dysaesthesia in the left periorbital region. A CT scan showed a lacrimal gland mass with areas of dense calcification. Biopsies of the left lacrimal gland revealed a silver material with associated chronic granulomatous inflammation and secondary calcification.

Periorbital Masson's tumor: a case series.

Intravascular papillary endothelial hyperplasia (IPEH) or Masson's tumor is an unusual variety of benign vascular tumor. Involvement of periorbital area is uncommon. We report 2 cases of periorbital IPEH and review relevant literature.

Yellow lid sign in Wegener's granulomatosis.

Orbital manifestations in Wegener's granulomatosis develop in over 50% of patients. Ischemic vasculitis and optic nerve compression result in visual impairment. This case report highlights the importance of the yellow lid sign in the diagnosis of orbital granulomatosis as well as provides an explanation for the reversal of this phenomenon.

Spontaneous intracranial hypotension: a cause of severe acute headache.

Severe acute headache is a common presenting symptom to an accident and emergency department. Spontaneous intracranial hypotension (SIH) is an increasingly recognised cause of these symptoms and has characteristic clinical and imaging findings. SIH is characterised by headache worse on standing, low opening cerebrospinal fluid pressures at lumbar puncture and uniform pachymeningeal enhancement with gadolinium enhanced magnetic resonance imaging of the brain, all in the absence of dural trauma.
