Thallium-201 single-photon emission computed tomography in the detection of retroperitoneal schwannoma.

摘要

We describe a patient with retroperitoneal schwannoma whose tumour was detectable by 201Tl single-photon emission computed tomography (SPECT). Physiologic uptake in the alimentary tract did not hamper the interpretation on SPECT images. Uptake by the tumour extending along the spinal nerve root was well recognised in axial and coronal images. Our results suggest that 201Tl SPECT may be useful in the detection of retroperitoneal schwannomas.
