OBJECTIVE In 2002 a new protocol was introduced based on the Canadian CT rules. Before this the Royal College of Surgeons "Galasko" report guidelines had been followed. This study evaluates the effects of the protocol and discusses the impact of the implementation of the NICE head injury guidelines-also based on the Canadian CT rules. METHODS A "before and after" study was undertaken, using d...

The efficacy of the posteroanterior and lateral ScoutView images with an abbreviated (every other cut) computed tomographic (CT) examination for skull fractures and associated intracranial trauma was analyzed. The every-other-slice CT study found all the brain injuries detected by the complete CT study. In addition, 20 of 21 skull fractures were identified on the posteroanterior and lateral Sco...

Objective- The purpose of this study was to assess and describe the radiographic anatomy of the bony structures in the head of sheep. Design- Experimental study. Animals- Fifteen mature Afshari sheep. Procedures- Radiographs were made out of the head of the animals in lateral and dorsoventral views. Radiographic anatomy was analyzed with results from gross dissection of 5 specimens. Results- De...

A 15-year-old boy presented with a gunshot wound in the left cerebellar hemisphere. He was confused and left cerebellar signs were noted. The patient underwent the first surgery for debridement of the entry wound in the left parietal region and second surgery to remove the bullet. However, the bullet could not be located via a left unilateral suboccipital craniectomy in the park bench position,...

Basilar skull fractures in horses can occur at any age, although young are particularly prone to this type of injury. This manuscript describes two foals with a basisphenoid bone fracture, clinical presentations ranging from mild neurological signs up severe compromise. The absence does not exclude fracture bone, as lethargy and retropharyngeal swelling may be the only signs. Radiography help d...

Gorham disease is a rare condition characterized by intraosseous neoplastic proliferation of hemangiomatous tissue with progressive, massive osteolysis. We present a pathologically proved case of Gorham disease that involved the left parietal bone in a 23-year-old man. Imaging studies including conventional radiography of the skull, CT, MR imaging, and Technetium-99 m (Tc-99 m) scintigraphy dem...

A retrospective study of 661 adult patients with open scalp wounds attending the Accident and Emergency Department of Glasgow Royal Infirmary, Glasgow, Scotland, was performed. Detailed information was recorded about history, nature of open wounds ('contused' or 'incised'), wound exploration and radiological findings. The commonest cause of injury was assault (40%), followed by falls (34%). Hal...

A 59-year-old male presented with a large cholesterol granuloma arising from the frontal sinus manifesting as a large, fluctuated, soft mass in his brow, compressing left eye. Skull radiography showed dilation of the frontal sinus. Computed tomography and magnetic resonance imaging revealed a cystic mass extending into the left orbit and anterior cranial fossa. Gross inspection at the frontal c...

Ultrasonographic examination is a readily available, inexpensive diagnostic technique for investigating osseous and soft tissue abnormalities of the equine head, is complementary to radiography, and may elucidate bony abnormalities not initially apparent on skull radiographs. Ultrasound may provide enough information to preclude computed tomography examination or may validate recommendations fo...

Bilateral parietal thinning is an uncommon condition. We present a 72 year-old female with no history of head injury, inflammatory or malignant disease who presented with painless scalp depression in bilateral parietal regions. The skull radiography and computed tomography findings are presented.
