Fifteen cases of primary sacral pathology were analyzed. High-resolution computed tomography was found to be the most accurate means of studying these cases. Certain anatomic changes involving the central canal and sacral foramina were found to be helpful in determining the type of pathology. Although conventional plain films, radionuclide bone scans, and myelography were useful in certain case...

Sacrum and pelvis structure and development in four species of Lacertidae currently assigned to different genera are studied: Lacerta agilis, L. vivipara, L. saxicola, Podarcis muralis. Size, shape, and position relationships between the cartilaginous elements as well as patterns and sequence of chondrification and ossification are given. Two sacral segments are characterized by a number of mar...

Laparoscopic sacral colpopexy can be used to treat vaginal vault and genital prolapse. After preparation, the vaginal apex is attached to the sacrum over the third and fourth sacral vertebrae using mesh.

BACKGROUND Leptomeningeal carcinomatosis occurs in patients with cancer at the rate of approximately 5%; it develops particularly in patients with breast cancer, lung cancer, melanoma, leukemia, or malignant lymphoma. We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the prima...

A 74-year-old man presented with a progressively worsening pain in sacrum and was diagnosed to have a sacral chordoma by biopsy in May, 2004. Percutaneous intratumoral injection with lipiodol-pingyangmycin suspension (LPS) was carried out under image guidance and repeated when the pain in sacrum recurred and the tumor increased. During a 6-year follow-up period, three sessions of this treatment...

Chordoma is a rare bone cancer that is aggressive, locally invasive, and has a poor prognosis. Chordomas are thought to arise from transformed remnants of notochord and have a predilection for the axial skeleton, with the most common sites being the sacrum, skull base, and spine. The gold standard treatment for chordomas of the mobile spine and sacrum is en-bloc excision with wide margins and p...

Pollen analysis was applied to a mummified homicide victim in Nebraska, U.S.A., to determine the location of death. A control sample showed the normal ambient pollen in the garage crime scene. Ambient windborne types, common in the air of the region, dominated the control. Internal samples were analyzed from the sacrum, intestine, and diaphragm. Microfossils were recovered from the rehydrated i...

A case was reported of a 67-year-old patient with right buttock pain radiating to the thighs and affecting his bipedalism and gait. With four months into the disease and a weight loss of 15 kilos, the patient underwent imaging tests which showed sacrum infiltration. The biopsy diagnosis was injury of bone tissue infiltrated by poorly differentiated adenocarcinoma. The rectal examination perform...

A 63-year-old man visited the clinic with numbness in the right hand. Magnetic resonance imaging demonstrated multiple low-intensity lesions in the cervical vertebrae and sacrum, which was suspicious of cervical bone metastasis. Fluorodeoxyglucose positron emission tomography/computed tomography revealed areas of increased fluorodeoxyglucose uptake in the thoracic esophagus, sternum and sacrum....

Tumors of the sacrum and related neurological and pelvic structures are rare pathologic conditions. Sacral tumors are a diagnostic challenge because patients often present with nonspecific complaints such as low back pain, sacrococcygeal joint pain, referred lag and buttock pain. Because of diagnostic and radiographic challenges, the detection of sacral mass can be delayed which complicates any...
