Pseudotumor of infancy and congenital muscular torticollis: 170 cases.
OBJECTIVE
To review pseudotumor of infancy (POI) and congenital muscular torticollis (CMT) and to suggest an algorithm for treatment.


METHODS
Retrospective review of cases from 1962 to 1998 at a tertiary care center.


METHODS
Patients included in this study were 81 boys and 89 girls who had a diagnosis of POI (n = 38) or CMT (n = 132) before 24 months of age.


RESULTS
For all patients, the mean age at diagnosis was 4 months; 54.1% had the left side of the neck affected, over 90% had a head tilt, and 2.4% had feeding difficulty as a result of the disorder. Plagiocephaly was present in 39.5% of patients with POI and 63.6% of patients with CMT; a neck mass, in 63.2% and 18.2%, respectively; and facial asymmetry, in 7.9% and 15.9%, respectively. All patients had a complete physical examination; 54.1% had plain cervical radiography, 4.1%, computed tomography, and 2.9%, ultrasonography. Passive range of motion was the initial treatment recommended for 65.3% of patients. Conservative treatment failed for 16 patients; subsequently, they had surgical treatment. Follow-up data were available for 159 patients; 85.5% experienced total resolution and 14.5% experienced subtotal resolution or long-term abnormality.


CONCLUSIONS
Children diagnosed with POI or CMT should be treated and observed for at least 12 months or until symptoms resolve. If symptoms persist 1 year after diagnosis despite conservative therapy, surgical treatment should be considered. The majority of children with POI or CMT experience total resolution of symptoms.
