Internal anomalies in thalidomide embryopathy: results of imaging screening by CT and MRI.

AIM: To examine the prevalence and detailed radiological findings of internal anomalies in thalidomide embryopathy (TE).

MATERIALS AND

METHODS

Whole-body image screening for internal anomalies using unenhanced whole-body computed tomography (CT) and head magnetic resonance imaging (MRI) was performed in 22 patients (13 women and nine men; mean age, 49 years; range, 47-51 years) with TE.

RESULTS

Among the 22 patients with TE, internal anomalies were detected in 19 (86.4%): anomalies of the auditory organ in 10 (45.5%), anomalies of the vascular system in six (27.3%), agenesis of the gallbladder in six (27.3%), hypoplasia or aplasia of the 7th or 8th cranial nerves in five (22.7%), block vertebrae in five (22.7%), fusion of the left lobe and quadrate lobe of the liver in three (9.1%), and others in five (22.7%), respectively.

CONCLUSION

In addition to limb defects or hypoplasia, various internal anomalies can be detected at a high incidence in TE using CT and MRI. Understanding these characteristic radiological findings may help radiologists detect a wide range of radiological findings of internal anomalies associated with TE.
