A quantitative study on the sacrum of the dog.

The aim of this study was to record sacral bone morphometry that may help in selection of the implant type and proper size in sacroiliac separation. For this reason, sacral lengths and width, the length of each sacral vertebrae, distances between cranial and caudal articular processes, vertical and transversal diameters of the cranial endplate, sacral tuberositas and articular surface areas were obtained from 11 dogs. Additionally, the transverse and vertical diameters of the bony structure and sacral canal were measured from six cross-sections. The data of the study were determined to be representative of the sacral values for average-sized dogs, which was confirmed statistically. The highest value was the sacral width among the linear measurements. The ventral sacral length was longer than the dorsal sacral length. The total lateral area of the sacral wing was measured as 677.46 (142.1)mm2. The transverse diameters of the first sacral vertebra important for screw implantation were 46.02 (4.33)mm and 44.18 (5.29)mm in the first and second cross-sections, respectively.

Magnetic resonance imaging appearance of metastatic Merkel cell carcinoma to the sacrum and epidural space.

Merkel cell carcinoma (MCC) is a rare malignant tumor of the skin and often is diagnosed histologically as lymphoma, melanoma and even metastatic small cell carcinoma of the lung (SCCL). Classified as a neuroendocrine tumor, clinically it originates in the head and neck region and may present with metastatic disease at the time of presentation [1]. Osseous involvement in the past has been described to involve regional facial bones only. We present the first reported MRI findings of distant osseous metastasis from a Merkel cell carcinoma to the lumbosacral spine with associated soft tissue and epidural involvement. Appropriate treatment and patient survival depend on prompt diagnostic imaging for establishment of metastatic disease. Previous reports have advocated CT for diagnosis and staging of distant metastases [2,3]. When spinal involvement is suspected, MRI may be a more suitable modality for assessment of the epidural space and appropriate staging and follow-up in such cases.

[Solitary infantile myofibromatosis of the sacrum].

The infantile myofibromatosis is the most common fibrous tumor of infancy. One may find solitary lesions of dermal, visceral, musculoskeletal and subcutaneous tissues. Multiple lesions without visceral involvement generally take a benign course. Because the lesion is commonly known only to pathologists, infantile myofibromatosis is often misdiagnosed and underreported. Therefore we present a review of the pathology and symptoms of infantile myofibromatosis together with a case report of a solitary lesion of bone.

[Treatment of tumors of the sacrum].

This article reviews the methods recommended in the literature for treating sacral tumors, paying particular attention to the most common sacral tumors and those of uncertain malignancy. These recommendations for treatment are compared and analyzed in the light of the authors' own results in the treatment of 30 sacral tumors.
