Mesenchymal chondrosarcoma is a rare malignant tumor. It may exhibit as a skeletal or extraskeletal tumor and usually contains calcified deposits. A lesion arising from sacrum is extremely rare. We present a 17-year-old male patient with clinical manifestations of lower back pain and sciatica. Computed tomography and magnetic resonance images of the patient depicted a poorly demarcated sacral t...

AIM The sacral canal has been frequently used as "a passage" for minimally invasive diagnostic and therapeutic procedures for spinal diseases. The aim of the present study was to investigate morphometric analyses of the sacral canal, hiatus, and surrounding structures according to different age groups and gender by using the "multidetector computed tomography" method. MATERIAL AND METHODS Mul...

STUDY DESIGN Prospective study OBJECTIVE.: The aim of this study was to evaluate variations in the sacral hiatus based on ultrasonographic images. SUMMARY OF BACKGROUND DATA Caudal epidural injection is commonly used for the treatment of lower back pain, but blind injections commonly lead to mistakes made at the injection site due to anatomic variations in the sacral hiatus. METHODS A total...

MRI plays a significant role in modern forensic anthropology to solve certain queries of legal / public concern. The objective of our study was to determine the sexual dimorphism of the first sacral vertebra (S1) in south Indian adults and to compare the differences in sacrum measurement of south India with literature. MRI of lumbo-sacral region was performed on 25 male and 25 female patients w...

Ganglioneuroma (GN) is a rare benign tumor of neural crest origin usually found in the abdomen, but may occasionally present at uncommon sites including the cervical, lumbar, or sacral spine. However, GNs of thoracic spine are extremely rare. In this report, we describe a 12-year-old girl with giant GN in the thoracic spine, who underwent successful resection (T1-4 level) of the tumor. Histopat...

A 59-year-old man with sacral chordoma had several resections of locally recurring disease during a 6-year period following diagnosis. The present hospital admission of the patient, now 65, was prompted by several weeks of pain in the right buttock and progressive difficulty in walking. A tender soft-tissue mass in the right buttock area, weakness and muscle atrophy of both lower extremities, a...

Background Leiomyomatosis peritonealis disseminate (LPD), is a rare disease in which multiple smooth muscles or smooth muscle-like nodules develop in a subperitoneal location in any part of the abdominal cavity. No reports of multiple congenital malformations associated with LPD have been found in English literature. Case presentation We report such a case of a 27 yr-old patient referred to our...

Primitive neuroectodermal tumors (PNET) are rare, and are even rarer when they arise from the spinal cord tissue. Therefore, we report a case of peripheral PNET that arose from the sacral spinal nerve root. The patient was a 30-year-old woman who presented with left lower extremity pain, and MRI revealed a neoplastic lesion in the left S1 nerve root canal of the sacral region. Subsequent imagin...

We present an interesting case of sacral perineural cyst which caused chronic perineal pain. Perineural cyst is relatively rare, especially the sacral region. Chronic perineural pain is an often encountered problem that is difficult to evaluate and sacral perineural cyst may be the etiology of chronic perineal pain in many instances.
