Skeletal scintigraphy has a high sensitivity but low specificity in early detection and follow up of hip diseases. Unexplained hip pain or indistinct X-rays may be the reason for scintigraphic examination. On the other hand, there is a wide range of clinical indications for nuclear medicine examination, such as metastatic and primary malignant disease, tumor-like lesions, inflammatory, infectious, degenerative and avascular diseases, and posttraumatic and postoperative changes. White blood cell scintigraphy is highly sensitive and highly specific in the detection of infectious disease of the hip. In the vast majority of cases, physiologic or postoperative granulocytic accumulation can be differentiated from infectious accumulation, which requires therapy.

Hip and pelvic injuries are relatively rare in the young athlete. Contusions and musculotendinous sprains are the most common injuries about the hip and pelvis. Apophyseal avulsion fractures and stress fractures are the most frequently encountered skeletal injuries. Each of these entities can be successfully treated with guided physical therapy following conservative management with rest, anti-inflammatory medications, and ice massage until the patient is pain free. Epiphyseal, diaphyseal, or pathologic fractures are rare entities that are secondary to violent trauma. These injuries are severe and often require operative intervention. Femoral neck fractures have a high rate of complications from avascular necrosis, nonunion, or malunion. Pelvic fractures have frequent associated genitourinary, abdominal, neurologic, and musculoskeletal injuries. Pathologic fractures are most commonly secondary to benign lesions, such as unicameral bone cysts, and less likely owing to malignancy. Finally, in children with hip pain during athletic activities, even with antecedent trauma, the sports clinician must screen for slipped capital femoral epiphysis, Perthes' disease, congenital subluxation of the hip, toxic synovitis, systemic neoplasia, or infectious process.

Adult chronic hip pain can be difficult to attribute to a specific cause, both clinically and radiographically. Yet, there are often subtle radiographic signs that point to traumatic, infectious, arthritic, neoplastic, congenital, or other causes. Stress fractures appear as a lucent line surrounded by sclerosis or as subtle lucency or sclerosis. Subtle femoral neck angulation, trabecular angulation, or a subcapital impaction line indicates an insufficiency fracture. Apophyseal avulsion fractures appear as a thin, crescentic, ossific opacity when viewed in tangent and as a subtle, disk-shaped opacity when viewed en face. Effusion, cartilage loss, and cortical bone destruction are diagnostic of a septic hip. Transient osteoporosis manifests as osteoporosis and effusion. The earliest finding of avascular necrosis is relative sclerosis in the femoral head. Subtle osteophytes or erosive change is indicative of arthropathy. Osteoarthritis can manifest as early cyst formation, small osteophytes, or buttressing of the femoral neck or calcar. Rheumatoid arthritis may manifest as classic osteopenia, uniform cartilage loss, and erosive change. A disturbance of the trabecular pattern might suggest an early permeative pattern due to a tumor. Knowledge of common causes of chronic hip pain will allow the radiologist to seek out these radiographic findings.

We describe a patient with hip pain who had a painful solitary pelvic bone lesion with a lytic, permeative appearance and minimal periosteal reaction, despite a relatively large soft tissue mass. Histologic examination and thorough evaluation revealed this solitary tumor to be a primary non-Hodgkin's lymphoma of the bone.

We performed 40 total hip arthroplasties with pelvic reconstruction in 37 patients with metastatic periacetabular tumor. 3 patients underwent bilateral periacetabular reconstructive surgery and 2 of these had bilateral procedures at the single operation. There were 8 Harrington class I, 7 class II, and 25 class III lesions. A modified Harrington procedure was employed. All patients showed improvements in hip pain, analgesic use, ambulation and mobility postoperatively. 1 prosthetic dislocation occurred after a fall at home 2 months following surgery. 2 patients had pulmonary emboli during the femoral procedure, 1 of whom died during surgery. There were no prosthetic loosenings. Preoperative CT and/or MRI are important for the study of metastatic involvement of acetabular bone. Durability of reconstruction requires appropriate use of acetabular mesh, Steinmann pins, acetabular reinforcement rings and long-stem femoral prostheses. Careful patient selection may improve quality of life. A sequential bilateral procedure should be considered for some patients.

Primary bone tumors are infrequently encountered in a sports medicine practice. We describe a case in which a young athletic woman with a medical history significant for ulcerative colitis initially presented to our clinic with chronic hip pain. Her initial roentograms were negative for boney pathology and her history and examination were consistent with trochanteric bursitis. However, follow-up radiographs performed 9 months later showed a radiolucent mass that eventually, after open biopsy and histologic evaluation, was determined to be giant cell tumor. This case shows the importance of repeat radiographic studies in patients whose joint pain does not respond or responds slowly to conservative therapy, despite initial normal findings. It also establishes that radiographic findings do not always correlate with actual disease process, for this lesion was found to be giant cell carcinoma--a diagnosis contrary to the original diagnosis of clear cell chondrosarcoma that was suggested by radiology.

In 1980, a 10-year-old boy was admitted to the authors' hospital with consciousness disturbance and vomiting. Computerized tomography (CT) scans revealed a pineal mass lesion and hydrocephalus. The tumor was totally removed and a ventriculoperitoneal (VP) shunt was inserted. Histological investigation of a surgical specimen revealed that it was a teratoma. Five years later, the patient was readmitted to the same institution with polyuria. Magnetic resonance (MR) imaging revealed a mass lesion in the suprasellar region. The patient received systemic chemotherapy, and the tumor disappeared; however, 2 years after the chemotherapy, MR imaging demonstrated a right lateral ventricular mass. The tumor was totally resected, and histopathological investigation revealed a teratocarcinoma. Three years after the chemotherapy, CT scanning revealed suprasellar and right lateral ventricular tumor recurrences, for which the patient received irradiation and chemotherapy. The tumors disappeared and the patient achieved complete remission that lasted longer than 10 years. On January 25, 2000, however, he noticed hip pain. Lumbar MR imaging demonstrated a spinal tumor below L-4 and also an abdominal tumor. The abdominal tumor was totally removed, and the histological findings identified it as a germinoma. The patient received systemic chemotherapy and the tumor disappeared completely. The authors believe that the suprasellar tumor was a metachronous germinoma and that it had metastasized through the intrathecal route and the VP shunt.

A 68 year old Ecuadorian man was investigated for polyuria, polydipsia and weight loss of 3 kg during the previous two months. Insulin dependent diabetes mellitus was diagnosed 10 year before admission and treated with appropriate diet and insulin (35 U/d). 18 months before was diagnosed in El Ecuador of "multiple liver nodes non-suggestive of malignancy". Physical examination showed a large multinodular petrous hepatomegaly. There was no evidence of skin lesions. Results of laboratory studies included a basal plasma glucose level that ranged between 275-367 mg/dl (N=60-100), glycosylated haemoglobin of 8.9% (N<5) and a serum albumin of 2.8 gr./dl (N=3.4-4.8). At admission non-other laboratory alterations were detected. Computed tomography showed a mass on the head of the pancreas with loco-regional lymph nodes and liver metastases. Tumor markers were normal. Fine-needle aspiration cytology of the liver masses revealed the presence of liver metastases of a non-differentiated malignant tumor. A 111In-DTPAOC scintigraphy revealed the presence of somatostatin receptors in the liver metastases, also detecting the presence of multiple bone metastases in the axial and appendicular skeleton. Plasma glucagon level was 678 pg/ml (N<250). A diagnosis of metastatic glucagonoma was established and therapy with streptozocin, 5-FU, insulin and synthetic somatostatin analogs was initiated. Three months after the therapy initiation the patient was symptom free. Some weeks after the patient suffered from left hip pain, and a control 111In-DTPA scintigraphy showed progression of his bone metastases. In conclusion, glucagonoma must be suspected in all diabetic patients with metastatic liver, even in absence of necrotic migratory erythema. In these circumstances, plasmatic glucagon level and somatostatin receptors scintigraphy will be a useful tool for establishing the final diagnosis.

We report a case in which low-dose FP (5-fluorouracil/cisplatin, 5-FU/CDDP) therapy was remarkably effective for stage IVB advanced hepatocellular carcinoma (HCC) with lung and bone metastases. 5-FU of 250 mg/body/day was continuously infused over 24 hours and CDDP of 10 mg/body/day was infused over 30 minutes from day 1 to day 5 in a week. Administration was continued for 4 weeks as 1 cycle. An 81-year-old woman was diagnosed with HCC in S3 and underwent a transcatheter hepatic arterial embolization (TAE) for the tumor in December 2000. The patient complained of lumbago and hip pain in July 2001 and was admitted for dysbasia in September 2001. On admission, the level of serum AFP and PIVKA-II elevated to a remarkable 59,300 ng/ml and 25,700 AU/ml. Chest computed tomography (CT) showed multiple bilateral lung metastases and abdominal CT showed a tumor 12 x 11 x 10 cm in diameter in the right, iliac bone. No recurrent sign was found in the liver except for the accumulation of Lipiodol. Low-dose FP therapy of 2 cycles was performed. The levels of serum AFP and PIVKA-II decreased to 374 ng/ml from 59,300 and to 35 AU/ml from 25,700, respectively, after this therapy. The CT findings revealed that a complete response (CR) was obtained for lung metastases and a partial response (PR) was obtained for bone metastases after completion of course 2, and maintained thereafter. The oral UFT of 600 mg was administered after completion of course 2 in the outpatient setting. The level of AFP and PIVKA-II decreased to 13.2 ng/ml and to 26 AU/ml, respectively, in February 2002. No sign of recurrence was seen during the 13 months of follow-up after low-dose FP therapy. Toxic events consisted of only leukopenia (grade 1). Her quality of life (QOL) was fair during this therapy. Low-dose FP therapy is possibly useful for patients with stage IVB advanced HCC.
