چکیده

A 9-month-old girl was evaluated in our emergency room for 1 03°F fever and decreased activity. Three weeks earlier, at another hospital , the patient had been treated with antibiotics and skin grafting for secondand third-degree scald burns. On the current admission, a nonfluctuant neck swelling was noted, but otherwise the results of the physical and neurologic examinations were normal. WBC was 21 ,600/J.tl , and cultures of CSF and blood grew Staphylococcus aureus . After admission, a gallium-57 citrate scan showed increased uptake of radionuclide in the cervical region, left shoulder, and right elbow, consistent with multifocal osteomyelitis. Routine cervical radiographs were not obtained. Emergency MR imaging of the head and upper cervical spine showed a large retropharyngeal soft-tissue mass consistent with an abscess (Fig . 1 ). The mass extended intracranially into the epidural space immediately anterior to the brainstem. Dislocation of the C1-C2 articulation and marked compression of the cervical spinal cord also were seen. During MR imaging, the patient suddenly stopped breathing and could not be resuscitated . Autopsy showed evidence of systemicS. aureus septicemia and of spinal cord compression associated with atlantoaxial subluxation caused by a large retropharyngeal abscess.

Grisel's Syndrome Induced by Mycobacterium tuberculosis

Grisel's syndrome is a non-traumatic subluxation of the atlantoaxial joints, which is caused by an inflammatory process in the upper neck. It is rare to find literary reports of Grisel's syndrome with an evident pathogen in a lesion. For the first time in Korea, we report a 36-year-old female with Grisel's syndrome having an atlantoaxial subluxation, which was caused by a retropharyngeal absces...

Acute Retropharyngeal Calcific Tendinitis in an Unusual Location: a Case Report in a Patient with Rheumatoid Arthritis and Atlantoaxial Subluxation

Retropharyngeal calcific tendinitis is defined as inflammation of the longus colli muscle and is caused by the deposition of calcium hydroxyapatite crystals, which usually involves the superior oblique fibers of the longus colli muscle from C1-3. Diagnosis is usually made by detecting amorphous calcification and prevertebral soft tissue swelling on radiograph, CT or MRI. In this report, we intr...

MR imaging of the cervical spine in rheumatoid arthritis.

The cervical spine was examined with MR imaging and conventional radiography in 23 patients with severe rheumatoid arthritis. All patients had neck pain and 17 also had neurologic symptoms. MR provided detailed information about soft-tissue lesions, vertebral dislocation, and narrowing of the spinal canal. Pannus surrounding the odontoid process was revealed in 14 patients, all with horizontal ...

An early MR observation of carotid involvement by retropharyngeal abscess.

We report early carotid involvement by retropharyngeal abscess in a 4-year-old boy. MR imaging showed enhancement of the wall and narrowing of the lumen of the internal carotid artery, which were thought to reflect spasm and/or arteritis. Prompt treatment may have prevented hemorrhagic and neurologic complications.
