Background: Primary extramedullary tumors involving multiple compartments around the spine are a technically demanding group of tumors whose extent traverses beyond the normal confines of those anatomical regions which fall in the common domain of neurosurgeons. In the following series, we present 12 patients who were diagnosed with primary spinal extramedullary tumors with multicompartmental extension, and whose surgical management was facilitated by a combined multidisciplinary approach involving surgeons of other superspecialties...

Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5), anterior tibia (n=1), posterior axilla (n=1), ischium (n=1), and trochanter (n=2). The template for a bilateral flap was used on the sacrum (n=8), arm (n=1), and anterior tibia (n=1)...

BACKGROUND: Extracranial and extraspinal ependymomas are extremely rare tumors mostly published in the literature as case reports. METHODS: MD Anderson Cancer Center institutional database was screened for patients with extra CNS ependymomas over a 25 year period. RESULTS: Eight patients with extra CNS ependymoma were identified. Five cases originated in the sacrum or subcutaneous sacral area, and the other 3 cases originating in the breast, lung and adnexa of the uterus...

BACKGROUND: Curative therapy for ES requires both chemotherapy and local control of primary tumor. There is no universally accepted standard approach to local control modalities. This survey was conducted to determine practice patterns and factors influencing the choice to offer various local control modalities to patients with ES of the spine and pelvis. METHODS: The survey consisted of four scenarios involving a 15-year-old girl who presented with Ewing sarcoma of thoracic vertebra, sacrum, iliac wing, and acetabulum with or without neurologic compromise...

Presacral ganglioneuromas are extremely rare benign tumors and fewer than 20 cases have been reported in the literature. Ganglioneuromas are difficult to be differentiated preoperatively from tumors such as schwannomas, meningiomas, and neurofibromas with imaging modalities. The retroperitoneal approach for resection of presacral ganglioneuroma was performed for gross total resection of the tumor. Recurrence and malignant transformation of these tumors is rare. Adjuvant chemotherapy or radiation therapy is not indicated because of their benign nature...

BACKGROUND: Chordomas are very rare tumors of the skull base and the sacrum. They show infiltrating and destructive growth and are known to be chemo- and radio-resistant. After surgical resection, the recurrence rate is high and overall survival limited. As current adjuvant treatments are ineffective, new treatment concepts are urgently needed. 5-aminolevulinic acid-based photodynamic therapy (5-ALA based PDT) showed promising results for malignant gliomas. However, it is unknown so far, whether chordomas accumulate protoporphyrin IX (PPIX) after application of 5-ALA and whether they are sensitive to subsequent 5-ALA based PDT...

BACKGROUND: Pelvic reconstruction after periacetabular tumor resection is technically difficult and characterized by a high complication rate. Although endoprosthetic replacement can result in immediate postoperative functional recovery, biologic reconstructions with autograft may provide an enhanced prognosis in patients with long-term survival; however, little has been published regarding this approach. We therefore wished to evaluate whether whole-bulk femoral head autograft that is not contaminated by tumor can be used to reconstruct segmental bone defects after intraarticular resection of periacetabular tumors...

The present study describes a novel surgical strategy used to treat immature pelvic Ewing's sarcoma (ES), one made possible owing to the intrinsic structure of the skeletally immature pelvis. A total of 12 children and adolescents with open triradiate cartilage received limb-salvage surgeries following a diagnosis of pelvic ES. In total, 3 patients with iliac lesions (2 lesions with extension into the sacrum) received surgical tumor excisions and allograft reconstructions. Another 8 patients with periacetabular lesions received trans-acetabular osteotomies and allograft reconstructions...

BACKGROUND: Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome characterized by severe hypophosphatemia and osteomalacia. Nonspecific symptoms make the diagnosis elusive. In addition, locating the responsible tumor(s) is challenging. The aim of this study was to investigate the clinical management and outcomes of TIO. METHODS: The clinical features, diagnostic procedures, treatment, and outcomes of 12 patients were reviewed retrospectively. RESULTS: The cohort comprised six men and six women (mean age 45...

Giant cell tumor (GCT) of bone is a locally aggressive benign neoplasm that is associated with a large biological spectrum ranging from latent benign to highly recurrent and occasionally metastatic malignant bone tumor. It accounts for 4-10% of all bone tumors and typically affects the meta-epiphyseal region of long bones of young adults. The most common site involved is the distal femur, followed by the distal radius, sacrum, and proximal humerus. Clinical symptoms are nonspecific and may include local pain, swelling, and limited range of motion of the adjacent joint...

Spinal subdural hematomas (SSDHs) are rare and usually associated with bleeding diatheses, trauma, iatrogenic injury, spinal vascular malformations, or intraspinal tumors. We report a case of a 75-year-old male who developed a symptomatic lumbosacral SSDH after undergoing resection of a right temporal glioblastoma multiforme. The patient subsequently recovered and was discharged home. Over the next two weeks he developed progressively worsening symptoms of lower back pain, lower extremity weakness, and urinary retention...

BACKGROUND: Locally advanced rectal cancer is frequently treated with a long course of preoperative chemoradiotherapy. We investigated the effect of moderate dose escalation with volumetric modulated arc therapy (VMAT) up to 50 Gy in 25 fractions compared to 3D conformal radiotherapy (3D-CRT) to 45 Gy in 25 fractions in rectal cancer patients. Dose-volume parameters, acute toxicity, and complete response rates were compared. MATERIAL AND METHODS: For both groups, 65 patients were selected from our database through availability...

Osteoblastomas are benign bone tumors that produce prostaglandin and promote inflammation. The aim of the present study was to describe the clinical and radiological characteristics of a pediatric osteoblastoma case over an 8-month postoperative follow-up. The case involved an 11-year-old female patient with normal somatic development, presenting with a chief complaint of sleep disturbance. The patient had no spontaneous pain or other readily evident possible causes. Magnetic resonance imaging (MRI) revealed a neoplastic lesion in the sacrum, with peritumoral edema...

BACKGROUND: Colorectal cancer (CRC) resembling submucosal tumor (SMT; CRC/SMT) is very rare. Because its biopsy is challenging, accurate preoperative diagnosis is also very rare. CASE PRESENTATION: A 55-year-old woman with a high serum carcinoembryonic antigen level underwent a computed tomography colonoscopy, which showed extrinsic rectum compression. A coronal magnetic resonance image showed a 4-cm low-intensity tumor between her rectum and sacrum. Endoscopic ultrasound (EUS) showed a 30-mm low-echoic lesion originating from the rectum...

AIM: To assess safety of rectum removal with distal sacral resection. MATERIAL AND METHODS: The short-term results of surgical treatment of primary and recurrent locally advanced rectal and anal cancer with sacral fixation have been analyzed. 32 patients underwent combined operations with sacral resection at the level of S2-S5. In 12 patients only one point of tumor fixation (F1) was revealed, 10 patients had two points of fixation (F2), three patients had three fixation points (F3) and in 7 cases the tumor was fixed to four points (F4) of fixation to different pelvic structures...

BACKGROUND: Computer navigation-assisted surgery for musculoskeletal tumors has shown to reduce the risk of intra-lesional margins in resection. Experiences with this method are still limited to smaller case series. METHOD: We reviewed our first experiences in 24 patients in whom computer navigation-assisted surgery had been performed. In 7 of these patients (6 male and 1 female), this has influenced the surgical treatment plan and navigation was used for both tumor resection and reconstruction...

BACKGROUND: Schwannomas are benign nerve sheath tumors and are most frequently encountered as soft tissue tumors of peripheral nerves of the head and neck or the extensor extremities. Osseous involvement is very uncommon with fewer than 200 cases described in the world literature, the majority of which arise in the skull (including mandible), vertebrae, and sacrum. Long bone involvement is highly unusual and of the approximately 20 cases described thus far, only five have been documented to arise in the femur...

Retrorectal tumors (RT) are uncommon and usually managed by open surgical excision. Laparoscopic excision for RT has been reported in only a small number of papers. We aimed to assess the laparoscopic approach for RT and to discuss the factors that made this procedure difficult. We performed laparoscopic excision using a five-trocar technique for neurogenic RT in three patients. Tumors were successfully excised laparoscopically in two patients. However, the third patient required open conversion because the tumor was strongly adhered to the sacrum and could not be mobilized by dissection, resulting in poor visualization of the dissected site...

Giant cell tumor of bone (GCTB) is commonly treated with surgery; however, surgery of GCTB in the sacrum may be challenging due to the associated risk. A conservative approach may be selective arterial embolization or zoledronic acid (ZOL) treatment; however, there are currently no studies investigating the efficacy of combining these two treatments. Denosumab may also be used; however, to the best of our knowledge, there are no reports of a stepwise approach for the use of all three treatments in a single patient...

Chordomas are rare bone tumors that arise from notochord remnants. They most commonly occur in the sacrum, but they also can be seen in the skull base, cervical spine, and thoracolumbar vertebrae. Chordomas account for 1 to 4% of all primary skeletal tumors. They are usually indolent, locally growing tumors. Distant metastasis has been reported in 3 to 48% of cases. When metastasis occurs, it is usually observed in the lung, bone, and liver. To the best of our knowledge, no case of a chordoma metastasis to the tongue has been previously reported in the literature...
