Imaging of childhood torticollis due to atlanto-axial rotatory fixation.
Atlanto-axial rotatory fixation is a rare cause of childhood torticollis. It may occur spontaneously or may be associated with trauma, upper respiratory tract infection or congenital abnormality of the cervical spine. Presentation is usually with persistent torticollis and "cock robin" deformity of the neck. In this paper the radiological experience in three patients is presented. Investigations included plain radiographs, plain anteroposterior tomography, CT and MRI. Displacement of the lateral mass of the atlas and the eccentric position of the odontoid peg can be seen in the plain films. CT scan can exclude fractures and confirm atlanto-axial rotation. The superimposition of CT images is demonstrated as a way of diagnosing subluxation. MRI offers better soft tissue differentiation and allows assessment of the integrity of the transverse ligament. This has an important bearing on the prognosis and may influence surgical treatment. It is important to recognise the plain film features of this uncommon condition and confirm the diagnosis with CT or MRI. The treatment options are discussed with particular reference to long term outcome.

Hemangiopericytoma of the colon: report of a case and review of literature.
A patient with a hemangiopericytoma of the colon is discussed. This is the second such case reported in the English medical literature. Soon after discovery of the tumor, the patient presented with a colonic intussusception with the tumor serving as the lead point. This was reduced by a hypaque enema, but the intussusception recurred twice more, being reduced again by hypaque enema and finally having to be reduced by colonoscopy. At surgery a left hemicolectomy with primary anastomosis was performed. The microscopic, ultrastructural, and pathologic aspects of hemangiopericytoma are discussed with special attention to lesions of the gastrointestinal tract.
Ileorectal anastomosis in patients with Crohn's disease of the colon.
Thirty-seven patients were studied who had an ileorectal anastomosis performed for Crohn's disease of the colon. Twenty-nine were done as a primary procedure and in eight the anastomosis was made after previous total or segmental colectomy. Three patients developed anastomotic leaks and all three patients died. No patient who had a diverting loop ileostomy performed at the time of ileorectal anastomosis developed anastomotic leaks before or after the ileostomy was closed. Of the 37 patients, three died postoperatively and another five have had less than a one year follow-up. Of the remaining 29 patients, 12 (41%) had recurrences in either the rectum or ileum. Half of the recurrences took place five or more years after surgery. Seven of the 12 patients with recurrences have had their anastomoses taken down. When this recurrence rate of 41% is compared with the recurrence of ileitis in patients after total colectomy and ileostomy for Crohn's disease of the colon, the incidence of recurrence is, as shown in many reports, not markedly dissimilar. Of the patients who develop a recurrence after ileorectal anastomosis, only about half will have to have their anastomoses taken down. In our study, 59% of the patients had no recurrence and another 20-5% had a recurrence but did not require 'take down' of the anastomosis. Thus, almost 80% of our patients at the time of this report have been able to lead a life unencumbered by an ileostomy, making ileorectal anastomosis for this disease a desirable procedure to consider in selected patients.
