BACKGROUND: Difficult resection of tumors from regions with complex local anatomy, such as the pelvis and sacrum, is likely to result in inadequate surgical margins (intralesional or marginal); this is because three-dimensional osteotomy is difficult particularly around the acetabulum. Additionally, removal of the joint makes reconstruction very difficult; thus, retention of good function also becomes difficult. In musculoskeletal oncology, computer navigation systems are still not widely used to prevent tumor-positive margins...

Secondary hypertension is relatively rare. Its etiologies are essentially renal or endocrine. The adrenocortical carcinoma, a rare malignant tumor, is one of the most exceptional causes of hypertension. We report the case of a young woman presenting with hypertension and ascites of great abundance. She had hypokalemia, hepatic cytolysis and cholestasis. Thoracic, abdominal and pelvic CT scans showed adrenal mass, liver and lung nodules, osteolytic lesions of the sacrum. The biopsy of liver nodules confirmed the diagnosis of a metastatic malignant adrenocortical carcinoma...

BACKGROUND: High-grade spindle cell sarcomas are a subtype of rare, undifferentiated pleomorphic sarcomas (UPSs) for which diagnosis is difficult and no specific treatment strategies have been established. The limited published data on UPSs suggest an aggressive clinical course, high rates of local recurrence and distant metastasis, and poor prognosis. CASE PRESENTATION: Here we present the unusual case of a 45-year-old male patient with a lumbosacral UPS extending into the sacrum...

Chordomas are a rare type of bone tumor that arises from the embryological remnant of the notochord. They originate at any point along the axial spine with the sacrum and the skull based region being the most commonly affected sites. Chordomas are slowly growing, indolent tumors, presenting insidiously, but also carry a high recurrence rate with a tendency to invade contiguous structure making their treatment challenging. The current standard of care for localized chordoma is aggressive cytoreductive surgery followed by high dose adjuvant radiotherapy...

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...
