ABSTRACTSubarachnoid hemorrhage (SAH) is an important but uncommon condition in the differential diagnosis of acute headache. Most authorities recommend that patients with suspected SAH undergo noncontrast computed tomography (CT) as a first diagnostic intervention. If the results of the CT scan are negative, a lumbar puncture should be performed. Many nonurban Canadian hospitals do not have CT scanners and must either transfer patients or consider performing lumbar puncture prior to CT. In selected patients, performing lumbar puncture first may be an option, but timing of the procedure and the interpretation of results is important.

AbstractObjectives:To describe a unique presentation of a predominantly extracranial glomus faciale tumour. To discuss the role of imaging in the differential diagnosis and evaluation of a hypervascular parotid mass. To review the previous literature concerning the glomus faciale tumour.Case report:A 54-year-old woman presented with a six-month history of facial weakness, pain and a parotid mass. Ultrasound revealed a hypervascular parotid mass and pre-operative core biopsy suggested a paraganglioma. Computed tomography defined its deep extent and demonstrated involvement of the petrous temporal bone along the descending portion of the facial nerve canal with a pattern of permeative lucency. A tumour was surgically removed which arose from the facial nerve from the second genu to the proximal divisions within the parotid gland and histology confirmed a paraganglioma.Conclusions:A facial nerve glomus faciale tumour should be considered in the differential diagnosis of a hypervascular parotid mass and may present in a predominantly extracranial location. Computed tomography will prove helpful in such a case in order to limit the differential diagnosis and to define the extent of skull base involvement.

Intestinal Metastasis

Despite the frequent rapid spread of esophageal cancers to other organs, metastases to the small intestine are uncommon. As such, this paper describes a case of a 60-year-old male who developed a small intestinal obstruction due to metastasis from esophageal carcinoma. This patient had received radical esophagectomy for esophageal carcinoma 14 months prior to the diagnosis. Furthermore, the important role of computed tomography scans played in composing the differential diagnosis will be explored. In order to relieve the obstruction, resection of the small intestine was performed, and the patient survived six months postoperatively.
