A case of mistaken identity: the role of lacrimal gland pleomorphic adenoma tissue diagnosis.

Purpose: Lacrimal gland lesions have diverse pathologies. Bone remodelling on imaging may suggest a benign lacrimal gland pleomorphic adenoma (LGPA) rather than a malignant process.

Methods: The authors report a case of malignant pleomorphic adenocarcinoma, which was misdiagnosed clinico-radiologically as a benign LGPA.

Hemibody pain relieved by microvascular decompression of the contralateral caudal medulla: case report.

Microvascular decompression (MVD) of cranial nerves has become an established treatment for trigeminal and (vago)glossopharyngeal neuralgia and for hemifacial spasm. The authors present the case of a 64-year-old man who had a 3.5-year history of severe, drug-resistant hemibody pain with sensory and autonomic disturbance.

Spinal cord injury following chiropractic manipulation to the neck.

Spinal cord injury is a rare complication of chiropractic treatment. This case report describes a 50-year-old man who developed neurological symptoms a few hours after manipulation (high velocity low amplitude [HVLA] technique) of the cervical spine. Magnetic resonance (MR) imaging of the cervical spine revealed intramedullary high signal at the C2/3 level of the right side of the cervical cord on the T2-weighted images.

Postoperative subdural haematoma and pneumocephalus mimicking TIA.

An 86-year-old man presented with left hand numbness and weakness 10 days after a resection of squamous cell carcinoma of the right side of the scalp. A CT head scan identified a right-sided, hypodense subdural collection without midline shift, with associated pneumocephalus. When the images were reviewed on bony settings, minute drill holes were identified penetrating the outer tables as expected, but also the inner table of the calvarium.

Radiologically manifested accessory extraocular muscles in thyroid eye disease.

The authors describe 3 patients with Graves orbitopathy who all have accessory orbital structures on orbital imaging. These structures are isodense on CT and isointense on MRI to the extraocular muscles and have a similar anatomical appearance to accessory extraocular muscles previously described in the literature. The authors propose that Graves orbitopathy involves these accessory muscles and makes them visible on imaging.

Ocular findings in pediatric patients with partial agenesis of corpus callosum.

Purpose: To evaluate the ocular associations with corpus callosum agenesis.

Methods: All children who had corpus callosum agenesis diagnosed by computed tomography or magnetic resonance imaging scans during a 10-year period were included in the study. A complete ophthalmological assessment was undertaken.

Mucin-secreting papillary adenocarcinoma of the hyoid bone: a unique case.

We present a unique case of a mucin-secreting papillary adenocarcinoma of intestinal type which has invaded and completely destroyed the hyoid bone and metastasized to the cervical lymph nodes bilaterally. The tumour is believed to have originated from a malignant thyroglossal duct remnant, and was managed with surgery and radiotherapy. We describe the case and discuss the literature regarding hyoid bone tumours.

General practitioners' use of magnetic resonance imaging: an open randomized trial comparing telephone and written requests and an open randomized controlled trial of different methods of local guideline dissemination.

Aim: To determine the impact and cost-effectiveness of telephone versus written access to magnetic resonance imaging (MRI), and of different strategies for disseminating locally produced guidelines, upon requests by general practitioners (GPs) for knee and lumbar spine investigation.

Material And Methods: Two sequential pragmatic open cluster-randomized trials were conducted within 39 general practices. The outcome measure in each trial was concordance of request with local guidelines.
