    Notes: Abstract. Cardiac leiomyosarcoma is a rare tumour which can grow either intramurally or extramurally. Its prognosis is dismal. Surgery lengthens survival, but recurrences usually occur in the short term. Gated MRI is useful for the assessment of cardiac masses since it provides fine spatial and contrast resolution. We present the case of a left atrial leiomyosarcoma whose recurrence was diagnosed by gated MRI. Our patient underwent a second resection but died soon after.

    Notes: Abstract. The prognosis for a patient with a musculoskeletal sarcoma has improved considerably over the past two decades largely due to the use of adjuvant chemotherapy. Surgical techniques have become more sophisticated with limb salvage, the preferred management in the majority of cases. Imaging plays an important role in the assessment of suspected local recurrence of tumor. This pictorial essay reviews the different imaging options and highlights various pitfalls in the detection and diagnosis of recurrence. The role of magnetic resonance imaging in this respect is stressed.

    Notes: Abstract The purpose of our work was to describe the clinical and mammographic patterns of breast cancer in women aged 35 years old or less. From 1980 to 1985, 92 women 35 years old or younger were treated in our institution for breast cancer. Their mammograms were reviewed to determine the breast density and to describe the mammographic lesion. The clinical examination found a palpable breast mass (n = 84), nipple discharge (n = 2), axillary lymph node involvement (n = 3), metastasis (n = 1) or was normal (n = 2). The mammograms exhibited dense (n = 59), mixed dense/fatty (n = 29) or fatty (n = 4) parenchymal breast. The mammograms showed opacity with well-defined (n = 13) or ill-defined borders (n = 34), spiculated opacity (n = 11), architectural distortion (n = 9), isolated clusters of microcalcifications (n = 13) or were normal (n = 18). The diagnosis of breast cancer in young womensis difficult, because mammographic accuracy is less reliable and benign disease is far more prevalent.

    Notes: Abstract. Teratomas of the nasopharynx occur usually in neonates. We present a case of teratoma which was discovered in an adult, and which relapsed after 34 years. The conventional radiograms, CT, MR, and histologic appearances are described.

    Notes: Abstract. Some knowledge of MR theory is required to be able to achieve high contrast between bone metastases and normal marrow. Three factors are used in MR to diagnose bone metastases: fat–water distribution, artifacts induced by bone trabeculae, and uptake of contrast medium. Using MR-histological correlations based on specimens of the lumbar spine, and studies of patients, we explain the advantages and limitations of sequences studying fat and water (spin-echo T1, STIR, in- and out-of-phase gradient echo, fat presaturation), bone trabeculae (gradient echo with long TE), and the injection of contrast medium.

    Notes: Abstract. We report a case of renal cell carcinoma with solitary metachronous contralateral adrenal metastasis occurring 23 years after radical nephrectomy. The patient was treated with adrenalectomy. He is alive with no evidence of disease 1 year postoperatively. Solitary metachronous contralateral adrenal metastases from renal cell carcinoma are rare clinical conditions that may occur very late. Metastasectomy is advocated and is probably beneficial for limited metastatic renal cell cancer.

    Notes: Abstract. Four factors can be used in MR of bone marrow: fat–water distribution, artifacts induced by bone trabeculae, diffusion, and uptake of contrast media. Fat–water is imaged using T1-weighted spin-echo, short tau inversion recovery (STIR), and fast STIR, in- and out-of-phase gradient echo, and fat pre-saturation sequences; bone trabeculae by gradient echo with long TE; diffusion by single-shot spin-echo. The injection of contrast media is a more easy and efficient way to improve the specificity. The value and limitations of those sequences are discussed in marrow replacements (metastases, lymphoma, leukemia) and in myeloid hyperplasia or depletion.

    Notes: Abstract Fourteen telangiectatic osteosarcomas are reported. They are rare, clinically and radiologically aggressive lesions, involving mainly the femurs of young patients, often misdiagnosed as aneurysmal bone cysts. An explanation for a characteristic early radiological appearance consisting of regular parallel striations of the shaft is suggested.
