Back pain is one of the chief complaints of the elderly. It may be either a chronic deep skeletal muscular pain or an acute circumscribed pain arising from nerve-root irritation. The main causes of back pain in older people are: 1) degenerative changes (spondylosis, osteoarthritis, ankylosing hyperostosis); 2) malignancy (multiple myeloma, metastases from carcinoma or lymphoma); and 3) metabolic disorders (osteoporosis, osteomalacia, chondrocalcinosis, Paget's disease). Mechanisms and variations are discussed in detail.

Pain syndromes in elderly patients are seldom psychogenic or due merely to "old age." Careful differential diagnosis is important, as judicious use of nerve blocks as adjunctive therapy often can relieve pain and restore activity. In the acute phase of shoulder pain, intrabursal injection of local anesthetic and steroid inhibits the inflammatory process. In the later stages, suprascapular nerve block relieves pain and interrupts afferent pain pathways. The occipital pain and headache of cervical arthritis also often respond to injection of 2 to 3 ml of long-acting anesthetic into the greater and lesser occipital nerves at the sites where they pierce the trapezius. Minor causalgia, shoulder-arm syndrome, or chronic traumatic edema may follow either forearm fracture or inflammation around the shoulder joint. Five stellate ganglion blocks with 1% lidocaine on alternate days, followed by 3 to 4 months of active and passive exercise, is the most effective treatment. This regimen usually produces a fully functional extremity. In degenerative disk disease, osteoarthritis, and metastatic disease, the cause of back pain is essentially the same--edema and inflammation of nerve roots at the intervertebral foramina. Injection of local anesthetic and steroid into the epidural space usually reduces swelling and inflammation. Patients are evaluated in 2 weeks and reblocked if improvement has plateaued. Pain relief most often is prompt and persists for an indefinite period.

Electromyographic examination may demonstrate severe segmental compromise of the posterior primary ramus and relative sparing of the anterior ramus as the earliest objective evidences of spinal and paraspinal metastases. Antecedent studies, including roentgenographic, radioisotopic and neurologic investigations, are often initially normal, failing to reveal the underlying cause of the progressive back pain. The present report demonstrates metastatic spread both through the paravertebral venous plexus and by direct extension in contiguous muscle. In this special instance, segmental 4+ fibrillations in the paraspinal muscles are electrophysiologic manifestations of a local, active process of denervation rather than a remote effect of the malignant disease, as has been suggested by others.

A 27-year-old woman with Peutz-Jeghers syndrome since age 11 years was hospitalized with a sudden onset of weakness of the right extremity, an expressive aphasia, and a three-month history of back pain. Liver and whole-body scintigrams demonstrated multiple metastatic disease; the brain scintigraphic study was compatible with infarction of the left hemisphere. Postmoretem examination two weeks after these studies showed extensive metastases in bone, liver, brain, lung, and left ovary. The source of the metastases was a malignant change from Peutz-Jeghers polyps.

Two cases of vertebral sarcoidosis in pediatric patients are presented. All such patients reported have been black, 13-15 years old, and have a history of back pain. Radiographs of the involved vertebrae show primarily lytic destruction with sclerotic borders in some of the lesions. Fungal infections, tuberculosis, pyogenic osteomyelitis, Hodgkin's disease and metastatic disease must be considered in every patient with vertebral sarcoidosis.

Bone scanning has been shown to have a higher rate of accuracy in diagnosing osseous metastatic lesions from carcinomas of the lung and breast. In the present report, we have demonstrated this to be true for osseous metastases from carcinomas of the colon and rectum. We found that a high percentage (75%) of patients who have pelvic or back pain have positive 99mTc bone scans for metastases in spite of the negative radiographs. The previously reported incidence of 5-6% of osseous involvement from these tumors is probably lower than the actual incidence, as these studies were reported without the benefit of bone scanning.

Three cases of hepatocellular carcinoma with ovarian metastases discovered during the patient's life are reported. A 31-year-old woman presented with back pain, and radiographic studies disclosed massive liver enlargement and bilateral ovarian tumors. The second patient, a 38-year-old woman, had an enlarged liver at the time of laparoscopic tubal ligation, and subsequently underwent right hepatic lobectomy for hepatocellular carcinoma. Three months later a left ovarian tumor was detected and a total abdominal hysterectomy with bilateral salpingo-oophorectomy performed. The third patient, a 68-year-old woman, presented with gastrointestinal symptoms and weight loss, and had bilateral ovarian tumors and widespread tumor at laparotomy. Two patients died of their disease at 18 months and 4 years 7 months; the third patient is alive with residual tumor at 7 months. The ovarian tumors, which were bilateral and multinodular in two cases and focally cystic in one case, ranged from 4 to 11 cm in maximum dimension, and had yellow-green or yellow sectioned surfaces. On microscopic examination, they were composed of cells with moderate to abundant eosinophilic cytoplasm growing diffusely and in nodules, nests, and trabeculae; cysts or glands were conspicuous in two cases. Bile was present in one tumor. The main differential diagnostic considerations were hepatoid yolk sac tumor and hepatoid carcinoma, primary or metastatic in the ovary. A variety of features, including the age of the patient, unilaterality or bilaterality of the ovarian tumors, distribution of disease, and microscopic features of the neoplasm, including the identification of bile, established the diagnosis. Metastatic hepatocellular carcinoma must be included in the differential diagnosis of oxyphil cell tumors of the ovary.

To assess the value of magnetic resonance imaging (MRI) in the investigation of patients with suspected but nonproven vertebral metastases 45 consecutive patients referred in a 6 month period with known primary malignancy and back pain in whom an isotope bone scan was reported as equivocal were studied. All patients had abnormal isotope uptake localized to the spine. Twelve patients were shown to have bony metastases on plain X-ray. In the remainder, where X-rays showed normal or benign appearance, MRI of the spine was offered. Twenty-four patients underwent MRI examination which showed vertebral metastases in 11 cases. Magnetic resonance imaging is shown to be a useful, noninvasive, complementary investigation for evaluation of patients known to have malignant disease and suspected of having vertebral metastases on bone scintigraphy.

A 70-year-old man, who had undergone operation for primary lung adenocarcinoma one and a half year ago, was readmitted to our hospital for back pain. The CT scan revealed liver, vertebrae and lymph nodes metastases. Because of severe back pain, irradiation to the thoracic vertebrae was performed first. Next, a catheter was inserted into the hepatic artery and an implantable reservoir for intra-arterial chemotherapy was also left in the subcutaneous tissue to treat the liver metastasis. Mitomycin C was injected intermittently in the hepatic artery more than 10 times. The liver metastasis became necrotic and almost disappeared. The patient was free from the back pain and there was no evidence of regrowth of the liver metastasis at the time of this report, which was 14 months after the discovery of the liver metastasis.

Eight patients treated for histologically confirmed primary spinal epidural non-Hodgkin's lymphoma diagnosed between January 1979 and August 1989 (6.6% of all cases of intraspinal lymphoma) were studied. There were six men and two women. The median age was 70 years (range, 43-80 yr). Patients sought treatment for a prodrome of back pain (median duration, 3 mo) followed by an acute neurological deterioration (median duration, 6 d). The most common findings were a discrete sensory level in 5 patients, hyperreflexia in 5 patients, and paraparesis or paraplegia in 5 patients. Radiographically, there was an absence of bony destruction by these tumors. All patients underwent a decompressive laminectomy, subtotal tumor resection, and spinal irradiation (median dose, 3800 cGy). Two patients had low-grade lymphomas (one B cell and one T cell), and 6 patients had intermediate-grade lesions (six B cell). Two patients with B-cell lymphomas (one low-grade and one intermediate-grade) developed metastatic disease 15 and 17 months after the initial diagnosis; no evidence of lymphoma developed in the other 6 patients. The median survival was 22 months (range, 2-71 mo). Lymphoma was the cause of death in only 1 of the 4 patients who died, and the 4 younger patients are alive and well. Primary spinal epidural non-Hodgkin's lymphoma should be a diagnostic consideration in the older patient who seeks treatment for spinal cord compression manifested by a prodrome of back pain, followed by a rapid neurological deterioration, normal plain spine radiographs, and neuroimaging consistent with an extradural compressive lesion. Surgery for this diagnosis followed by spinal irradiation should result in significant neurological improvement.
