Physical Findings

This report describes a 37-year-old man presenting with a gait disturbance due to spastic paraparesis. Physical findings showed typical features of Albright's hereditary osteodystrophy, including short stature, obesity, brachydactyly and dental hypoplasia. He was diagnosed as having pseudohypoparathyroidism type Ia, on the basis of his hypocalcaemia, hyperphosphataemia, increased plasma level of parathyroid hormone (PTH), and the unresponsiveness to exogenous PTH loading of his urinary excretion of both nephrogenous cyclic adenosine monophosphate and phosphate. Magnetic resonance imaging and myelographic computed tomographic scans clearly demonstrated severe compression of the spinal cord at T 9/10 by tumour-like ossifications of the paravertebral ligaments. Neurosurgical decompression therapy was, therefore, performed to alleviate his spastic paraparesis. This was a rare case of pseudohypoparathyroidism complicated with spinal cord compression caused by ectopic ossification of the ligaments.

Cervical Osteochondroma

✓ The authors present the case of a 24-year-old woman with osteochondromatosis who experienced gradual onset of cervical myelopathy. Metrizamide myelography and metrizamide-enhanced computerized tomography revealed extensive extradural cervical spinal cord compression, and surgical removal of a lower cervical osteochondroma was performed. Although osteochondroma is the most common of the benign bone tumors, neurological involvement due to spinal cord compression is rare. Somatosensory evoked responses obtained before, during, and after surgery are also presented.

Abstract OBJECTIVE Chordomas are rare primary bone tumors for which surgery is classically the first-line treatment. However, safe margins are often difficult to obtain, so that patients are at risk of local recurrence. Because radiation therapy and systemic chemotherapy show limited effectiveness, we report the use of direct intratumoral chemotherapy (IC) to treat recurrent chordoma. CLINICAL PRESENTATION A 46-year-old man presented with a recurrent cervical chordoma after surgery and radiation therapy. This recurrence manifested as C4–C5 spinal cord compression. TECHNIQUE Three 22-gauge needles were inserted at the upper, middle, and lower parts of the tumor and advanced under computed tomographic guidance while injecting local anesthetic. A 5-mg/mL carboplatin solution was combined with epinephrine (to increase the concentration and antitumor effect of carboplatin) at a final concentration of 0.01 mg/mL and an iodinated contrast agent. We injected 3 to 5 mL of this solution over 5 minutes through each needle under computed tomographic guidance. Eleven intratumoral treatments were performed during an 18-month period. CONCLUSION A marked clinical response with regression of the spinal cord compression was observed, without specific toxicity. A good partial response was obtained with a 42% decrease in tumor volume (from 69 to 40 cm3). Moreover, the central part of the tumor showed tumor necrosis, as confirmed by histological examination. Thus, in patients with this rare tumor, intratumoral chemotherapy may be a valid treatment option when surgery and radiation therapy fail. Furthermore, intratumoral chemotherapy in combination with surgical treatment should be considered to improve the local control rate.
