Primary malignant pericardial mesothelioma (PMPM) is an aggressive tumor that originates from the mesothelial cells of the pericardium. PMPM with extensive atrial infiltration and bone metastasis is extremely rare. The diagnosis and staging of PMPM based on anatomical imaging may be difficult when concurrent pericardial and pleural effusions are present. A 28-year-old man presented with progressive chest pain. Concurrent pericardial and pleural effusions were identified on computed tomography. On echocardiography, mild thickening and adhesions of the pericardium with the right ventricle and atrium were observed...

Presacral myelolipomas are rare, benign, asymptomatic tumors composed of mature adipose tissue and hematopoietic elements. Presacral myelolipomas can occur in patients with a medical history of malignancy, steroid use, and/or endocrine disorders including diabetes mellitus. A 65-year-old man with no specific medical history experienced temporal abdominal pain without bowel symptoms that lasted a few hours. By the time he visited a hospital, the pain had diminished. Computed tomography failed to detect any abnormality in the abdominal or pelvic organs that would have caused the abdominal pain but revealed a lesion 4 cm in diameter in the frontal sacrum...

This study was aimed to analyze the survival of patients with spinal chordomas. Patients' data in the Surveillance, Epidemiology, and End Results (SEER) database were retrieved and analyzed statistically. There were 765 patients with spinal chordomas between 1974 and 2013. The overall survival did not improve significantly over decades for patients receiving surgery and radiotherapy (SR) (P = 0.221). There were significant differences in overall survival among subgroups of patients receiving surgery (S), radiotherapy (R), and neither S nor R (NSR) (P = 0...

BACKGROUND: Surgery for the treatment of recurrent pelvic malignancy is challenging. Sphincter-preserving surgery (SPS) has been applied in limited cases. Transanal endoscopic approach (TEA) has been used for primary rectal cancer, predominantly for hybrid transabdominal-transanal total mesorectal excision. Here, we describe the use of TEA as a hybrid approach in a case of recurrent ovarian cancer. CASE PRESENTATION: A 59-year-old woman had recurrence of serous ovarian adenocarcinoma in the vaginal stump, near the site of anastomosis from a rectal resection 18 months previously...

BACKGROUND: Spinal chordomas are rare primary osseous tumors that arise from the remnants of the notochord. They are commonly considered slow-growing, locally invasive neoplasms with little tendency to metastasize, but the high recurrent rate of spinal chordomas may seriously affect the survival rate and quality of life of patients. The aim of the study is to describe the epidemiological data and determine the prognostic factors for decreased survival in patients with primary spinal chordoma...

Colorectal cancer, a malignant tumor arising from the colon or rectum, is a common cancer in China, with most patients diagnosed at the advanced stage or locally advanced stage. Large tumor size results in the invasion of adjacent organs and the multiple organ involvement, which poses certain challenges for clinical treatment. When facing advanced stage colorectal cancer, some surgeons do not consider surgery, a reasonable option. However, in fact, multi-disciplinary treatment can achieve relatively good treatment outcomes in patients with advanced stage or locally advanced stage colorectal cancer...

BACKGROUND: Effects of high-dose radiation using protons and photons on bone are relatively unexplored, but high rates of insufficiency fractures are reported, and the causes of this are incompletely understood. Imaging studies with pre- and postradiation scans can help one understand the effect of radiation on bone. QUESTIONS/PURPOSES: The purpose of this study was to assess the effects of high-dose radiation on the trabecular density of bone in the sacrum using CT-derived Hounsfield units (HU)...

BACKGROUND: Navigation-assisted resection has been proposed as a useful adjunct to resection of malignant tumors in difficult anatomic sites such as the pelvis and sacrum where it is difficult to achieve tumor-free margins. Most of these studies are case reports or small case series, but these reports have been extremely promising. Very few reports, however, have documented benefits of navigation-assisted resection in series of pelvic and sacral primary tumors. Because this technology may add time and expense to the surgical procedure, it is important to determine whether navigation provides any such benefits or simply adds cost and time to an already complex procedure...

Giant cell tumors (GCTs) are rare, benign, and locally aggressive primary bone neoplasms. Spine is seldom affected, especially above the level of sacrum. In this report, we describe a case with GCT of the cervical vertebrae which causes collapse of the corpus. A 32-year-old female presented with gradual neck pain and abrupt paresthesia of the left hand. Computed tomography scan showed C6 vertebral collapse and magnetic resonance imaging demonstrated vertebral plana of C6 by a low signal intensity lesion on T1- and T2-weighted images...

The patient was a 59-year-old man. He was admitted to our hospital because of increasing anal pain with induration of the perianal region. There were large secondary orifices with mucous discharge on the left side of the perineal resion and buttock. We diagnosed adenocarcinoma on analysis of a biopsy specimen from induration of the perianal region. Pelvic CT and MRI showed that the tumor spreaded within the pelvis, with invasion of the prostate and sacrum. We performed neoadjuvant chemoradiotherapy preoperatively...
