We present a case of multifocal osteosarcoma (MFOS) arising 11.5 years after successful treatment of bilateral retinoblastoma.
The clinical, imaging and pathological findings at onset, after therapy, and during follow-up are described. Fluorescent
in situ hybridization did not reveal a deletion of the RB-1 retinoblastoma gene, although the presence of an inactivating
mutation invisible to this method cannot be ruled out. The MFOS may have been a second multifocal tumor associated with the
original retinoblastoma or a post-irradiation sarcoma with extensive metastases.

We present a case of sarcomatoid renal cell carcinoma with multiple sclerotic skeletal metastatic lesions. Renal cell carcinoma
is frequently metastatic at presentation, with a high incidence of skeletal involvement, classically described as osteolytic.
However, sclerotic or osteoblastic metastatic skeletal lesions from renal cell carcinoma are rare, with only two previous
reports identified in the literature, neither of which involved the sarcomatoid variant of renal cell carcinoma. In our case
the sclerotic metastases were characterized by bone scan, computed tomography (CT), magnetic resonance imaging (MRI), and
histologic analysis.

Two cases of osteogenic sarcoma with skeletal muscle metastases are described. A 40-year-old woman presented with progressive
swelling of both calves and a soft tissue back lump. She had been diagnosed with mandibular chondroblastic osteogenic sarcoma
6 years earlier. Radiographs showed calcified masses. MRI scans and bone scintigraphy revealed multiple soft tissue masses
in both calves. Bone scintigraphy also showed uptake in the back lump, right thigh and left lung base. Biopsy confirmed metastatic
chondroblastic osteogenic sarcoma, which initially responded well to chemotherapy. However, the metastatic disease subsequently
progressed rapidly and she died 21 months after presentation. The second case concerns a 20-year-old man who presented with
a pathologic fracture of the humerus, which was found to be due to osteoblastic osteogenic sarcoma. He developed cerebral
metastases 17 months later, followed by metastases at other sites. Calcified masses were subsequently seen on radiographs
of the abdomen and chest. CT scans confirmed the presence of densely calcified muscle metastases in the abdominal wall, erector
spinae and gluteal muscles. The patient’s disease progressed rapidly and he died 30 months after presentation.

Malignant chondroblastoma presenting as a recurrent pelvic tumor with DNA aneuploidy and p53 mutation as supportive evidence of malignancy 总被引:1,自引:0,他引:1

We report a rare case of malignant chondroblastoma, which presented in a 47-year-old man as a recurrent tumor, 18 years following
wide excision of a typical pelvic chondroblastoma. Radiologic studies of the recurrent tumor showed a large, lytic, destructive
lesion of the right pelvic bones and femur, with a pathologic fracture of the latter, a large pelvic soft tissue mass, and
multiple pulmonary metastases. Biopsy tissue showed typical features of chondroblastoma, but also increased nuclear atypia,
hyperchromasia, and pleomorphism, compared to the original tumor, and, most significantly, abnormal mitotic figures. Immunohistochemical
studies of the recurrent tumor revealed p53 mutation and extensive proliferative activity, and flow cytometric studies showed
DNA aneuploidy, none of which was present in the original tumor. The patient received chemotherapy and radiation, but died
of disease eight months after presentation. We also review chondroblastoma in general, to assign this unusual lesion to a
tumor subtype.

MR imaging of brachial plexopathy in breast cancer patients without palpable recurrence 总被引:3,自引:0,他引:3

Objective. To investigate the role of MR imaging in detecting brachial plexus (BP) abnormalities in breast cancer patients with plexopathy
but without palpable masses.
Design. MR imaging of the BP was performed on 26 breast cancer patients with brachial plexopathy without palpable regional masses,
using 0.5 T and 1.5 T imaging systems. Findings were correlated with the clinical diagnoses.
Patients. Twenty-six patients with brachial plexopathy and history of breast cancer were enrolled in the study. All patients presented
with plexopathy symptoms. Fourteen patients were positive and 12 patients were indeterminate for BP metastasis according to
clinical criteria.
Results and conclusion. MR imaging demonstrated masses involving the BP representing metastases in two patients. Nine patients had other regional
abnormalities with a normal brachial plexus. It is concluded that MR imaging is useful in the assessment and direction of
therapy of brachial plexopathy in breast cancer patients by detecting both metastases to the BP as well as other abnormalities,
unrelated to the BP, which may explain the patient’s symptoms.

Isolated penile metastasis from bladder carcinoma 总被引:1,自引:0,他引:1
Metastases of the penis are uncommon, with only approximately 300 cases reported since 1870. In up to 70 % of patients, the
primary tumour is located in the urogenital tract. Furthermore, isolated metastases of the penis are exceptionally rare. We
report a case of solitary squamous cell metastasis of the penis presenting with painful swelling initially thought to be inflammatory
in origin. The CT and MR imaging findings are presented with a short review of the literature.

We describe the imaging features of a giant geode of the distal humerus in a patient with rheumatoid arthritis, which presented

A 9-year-old boy was diagnosed with chronic recurrent multifocal osteomyelitis affecting multiple sites. During an 8-year

Intraosseous schwannoma (neurilemmoma) is an extremely rare, benign neoplasm, constituting less than 0.2% of primary bone
tumors. It infrequently involves the bones of the hand. We present a case of intraosseous neurilemmoma of the metacarpal.

Chronic ulcers of the leg are common in Brazil, perhaps more common than in the developed world. We report a case of a chronic
ulcer of the leg following extensive scarring due to a bite by a venomous snake, which eventually led to a squamous cell carcinoma.

We report a case of lntra-articular regional migratory osteoporosis of the knee in a 53-year-old man. The case demonstrates
an unusual pattern of migration of the marrow edema within the knee joint. This phenomenon has received scant attention in
the radiological literature.

We report on a rare, calcified, plasma cell tumor of the spine causing progressive myelopathy. Other unusual features were
the lack of an osseous lesion at the site of the mass, considerable calcified amyloid within the mass but no identifiable
amyloid elsewhere, and normal serum immunoelectrophoresis.

Differentiation of vascular abnormalities from soft tissue sarcomas may be difficult on clinical grounds, but is usually possible
on imaging criteria. We report the MRI and digital subtraction angiography (DSA) findings in a patient presenting with a mass
behind the knee. We discuss differentiating features and review the literature of similar cases.

Multiple hereditary osteochondromatosis is an uncommon autosomal dominant condition in which patients are predisposed to the
development of chondrosarcoma. We report a case of a patient who developed a secondary low-grade chondrosarcoma in this setting.
The tumor was associated with an unusual multinodular invasive growth pattern into a pre-existing bursa that was present overlying
the osteochondroma.

Primary hyperparathyroidism is rarely caused by carcinoma. We report a patient who manifested many of the clinical and radiographic
features of the disease. When encountering symptomatic hypercalcemia with or without a palpable neck mass, carcinoma should
be considered in the differential diagnosis. Patient survival depends on an aggressive surgical approach to the primary lesion
and recurrent disease.
