Fig. 1A 49-year-old man with renal cell carcinoma of left kidney who was
referred for palliative treatment of refractory painful metastasis in L3.
Axial CT scans show soft-tissue mass involving vertebral body, posterior wall,
and ipsilateral pedicle (A) and same mass with two infused 18-gauge
radiofrequency needles inserted (B).
Fig. 1B 49-year-old man with renal cell carcinoma of left kidney who was
referred for palliative treatment of refractory painful metastasis in L3.
Axial CT scans show soft-tissue mass involving vertebral body, posterior wall,
and ipsilateral pedicle (A) and same mass with two infused 18-gauge
radiofrequency needles inserted (B).
Fig. 1C 49-year-old man with renal cell carcinoma of left kidney who was
referred for palliative treatment of refractory painful metastasis in L3.
Posttreatment CT control scan shows air bubbles within treated lesion, a sign
of necrosis.
Fig. 2A 65-year-old man who previously underwent surgery for prostatic
cancer and was referred with paresthesia for palliative treatment of
refractory painful metastasis in T10. CT scan shows extensive involvement of
either vertebral body or pedicles, with right paravertebral mass involving
posterior arc of ipsilateral rib.
Fig. 2B 65-year-old man who previously underwent surgery for prostatic
cancer and was referred with paresthesia for palliative treatment of
refractory painful metastasis in T10. CT scan shows two infused 18-gauge
radiofrequency needles that were inserted into paravertebral mass under CT and
fluoroscopic guidance.
Fig. 2C 65-year-old man who previously underwent surgery for prostatic
cancer and was referred with paresthesia for palliative treatment of
refractory painful metastasis in T10. CT scan shows 10-gauge vertebroplasty
needle that was placed into vertebral body between contralateral rib and
pedicle under CT and fluoroscopic guidance, and 18-gauge radiofrequency needle
that was inserted through the 10-gauge needle (arrow).
Fig. 2D 65-year-old man who previously underwent surgery for prostatic
cancer and was referred with paresthesia for palliative treatment of
refractory painful metastasis in T10. CT and fluoroscopic control image after
radiofrequency plus vertebroplasty shows oval paraspinal necrotic area, with
cement in vertebral body.
Fig. 3A 52-year-old man with history of prostatic carcinoma previously
treated by surgery who was referred for palliative treatment of refractory
painful metastasis in T10. CT scan shows left paraspinal soft-tissue lesion,
with involvement of ipsilateral pedicle and posterior arc of ipsilateral
rib.
Fig. 3B 52-year-old man with history of prostatic carcinoma previously
treated by surgery who was referred for palliative treatment of refractory
painful metastasis in T10. CT scan shows two infused 18-gauge radiofrequency
needles that were inserted through posterior approach with patient prone.
Fig. 3C 52-year-old man with history of prostatic carcinoma previously
treated by surgery who was referred for palliative treatment of refractory
painful metastasis in T10. Posttreatment CT control scan shows air bubbles
within treated lesion, a sign of necrosis.
Fig. 3D 52-year-old man with history of prostatic carcinoma previously
treated by surgery who was referred for palliative treatment of refractory
painful metastasis in T10. MR follow-up image shows round-shaped hypointense
area corresponding to ablated tissue.
