Purpose: The purpose of the study was to detect and safely diagnose pn
eumatocysts by means of computed tomography. Methods: From September 1
995 to May 1996 computed tomography of the pelvis was performed in six
patients for various indications. A slice thickness of 8 mm was emplo
yed for all studies. One patient had undergone surgery for hyperparath
yroidism nine years previously. Attenuation values within the coincide
ntally diagnosed pneumatocysts were obtained. Results: We found a tota
l of 14 pneumatocysts juxtaarticular to the sacroiliac joint, Three pa
tients demonstrated a bilateral intraarticular vacuum phenomenon, yet
a joint communication was not found. The lesions did not coincide with
inflammation, tumour or trauma. Conclusion: Pneumatocysts are benign
bone lesions associated with arthrotic changes of the sacroiliac joint
. Computed tomography is the modality of choice for the diagnosis of p
neumatocysts.
