The current report presents a case of a 78-year-old male with sacral chordoma, showing an aggressive clinical course. The patient underwent sacral resection, however, nine months later, multiple metastases were detected by magnetic resonance imaging. The metastases progressed rapidly and 15 months following surgery the patient succumbed to respiratory dysfunction. An autopsy revealed multiple m...

BACKGROUND Chondromyxoid fibroma (CMF) is an extremely rare, benign cartilaginous tumor that makes up <0.5% of all bone tumors, typically presenting in the second or third decade of life. CMF of the sacrum is exceedingly rare, with only seven documented cases reported in the neurosurgical literature. CASE DESCRIPTION We report a case of a 35-year-old female with a 3 month history of lower bac...

Sacral chordoma is a rare spine tumor with a high recurrence rate even after optimal therapy. Previous studies have demonstrated that the PI3K/AKT pathway plays a pivotal role in chordoma, and high expression of pAKT is associated with poor prognosis. Recently, PHLPP was recognized to be a tumor suppressor that targets AKT. We analyzed the expression of PHLPP1 and AKT2 in 37 chordoma samples an...

BACKGROUND This study determined the landmarks for caudal epidural block (CEB) after morphometric measurements of the sacral hiatus on dry sacral bones. Anatomical features of the sacral hiatus of clinical importance during CEB, along with distances and angles of use in detecting the apex, were measured. This provides detailed knowledge of the anatomy of the sacral hiatus and practical landmark...

STUDY DESIGN Cross-section analysis. OBJECTIVE A quality-of-life oriented scoring system for evaluation of lower limbs, bladder, and bowel functions of patients after sacral tumor resection has been proposed and was adopted in a clinical research. SUMMARY OF BACKGROUND DATA Surgical resections of sacral tumors usually cause postoperative neurologic deficits. A widely agreed scoring system f...

Src-associated in mitosis of 68 kDa (Sam68), also known as KHDRBS1 (KH domain-containing, RNA-binding, signal transduction-associated 1), is a member of the signal transduction and activation of RNA family. Previous studies have demonstrated that the aberrant expression of Sam68 is associated with the progression and prognosis of a variety of cancers, but little is known about its expression an...

background and importance: perineural cysts, also known as tarlov cysts, are benign cysts of the spinal cord containing a collection of cerebrospinal fluid. they most frequently originate in the sacral spine and can be asymptomatic. case presentation: we presented a 30-year-old woman who was referred to our clinic with an 8-month history of perianal paresthesia, slowly progressive lower back pa...

Background. We report on 19 cases of giant cell tumor of bone (GCT) affecting the spine or sacrum and evaluate the outcome of different treatment modalities. Methods. Nineteen patients with GCT of the spine (n = 6) or sacrum (n = 13) have been included in this study. The mean followup was 51.6 months. Ten sacral GCT were treated by intralesional procedures of which 4 also received embolization,...
