A 54-year-old woman visited Gangnam Severance Hospital for left side flank pain. She had a history of total removal of malignant melanoma on the left eye ball 20 years prior. No evaluation had been performed since then. A paravertebral mass at thoracic ninth level (T9) was discovered on spinal magnetic resonance imaging, and pathology confirmed malignant melanoma. Following positron emission tomography-computed tomography, no other metastasis was discovered. After removal of the paravertebral mass, palliative chemotherapy (dacabarzine + tamoxifene) was administered in 3 cycles over 2 months...

PURPOSE: Although the overall incidence of bone metastasis is not known, over one-half of the people who die of cancer in the USA every year are thought to have bone involvement. In this study we have developed a method to quantify the metabolic and anatomic changes induced by different types of bone metastases in cancer patients using PET/CT images. PATIENTS AND MATERIALS: Seventy-three cancer patients with no previous history of chemotherapy or radiotherapy who had definite bone metastases documented by PET/CT and other conventional modalities were selected for this study...

Brain metastases in patients with breast cancer are associated with a poor survival rate. A small number of studies have challenged this premise, suggesting that survival times following brain metastasis differ significantly between breast cancer subtypes. In the current study, overall survival (OS), brain metastases-free survival (BMFS) and survival following brain metastases (SFBM) were found to be associated with the intrinsic breast cancer subtype. A total of 1,147 patients with invasive breast cancer who were treated at the Hannover Medical School between January 2004 and December 2010 were included, from which 54 patients with brain metastases were identified...

Ewing's sarcoma is a primary bone cancer that mainly affects the long bones. This malignancy is particularly common in pediatric patients. Primary cranial involvement accounts for 1% of cases, with occipital involvement considered extremely rare. In this case study, primary occipital Ewing's sarcoma with a posterior fossa mass and subsequent relapse resulting in spinal seeding is reported. A 3-year-old patient presented with a 1-year history of left-sided headaches, localized over the occipital bone with progressive torticollis...

BACKGROUND Sarcomatoid carcinoma is a rare, aggressive, malignant cancer composed of sarcoma and sarcoma-like components, and can occur in different organs such as the thyroid gland, bone, skin, breast, pancreas, liver, urinary tract, and lung. Pulmonary sarcomatoid carcinoma accounts for only a small percentage of lung cancers and has histological variants that include pleomorphic carcinoma, giant cell carcinoma, spindle cell carcinoma, carcinosarcoma, and pulmonary blastoma. CASE REPORT Here, we present a case of sarcomatoid carcinoma in a 63-year-old HIV-positive Hispanic male who presented with back pain, dry cough, and weight loss...

Laryngeal cancer metastases are relatively rare and mainly affect the lung. The medullary localization remains exceptional. We report the case of a patient followed for operated laryngeal cancer and whose oncologic control revealed a medullary localization. A patient followed for squamous cell carcinoma of the larynx, treated in 2010 by a partial surgery whose endoscopic control at 5 years revealed the presence of right arytenoid edema without suspicious lesions, multiple biopsies were made and which returned negative...

Distant metastases change the prognosis of patients with nasopharyngeal carcinoma (NPC) which most commonly metastasizes to the bone. (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) is reported as useful in imaging NPC metastases. Our study assesses the incidence and distribution of bone metastases detected by (18)F-FDG PET/CT in NPC. 717 (18)F-FDG PET/CT scan reports of histologically proven NPC patients imaged in Singapore General Hospital, Singapore, between 2003 and 2009 were reviewed for the total number of metastases (scanned from vertex to mid-thigh) and analyzed for distribution...

We describe a patient who initially presented with a mixed thymic tumor and developed myasthenia gravis 8 years following thymectomy with recurrence of metastatic disease. Metastasis to the pleura, mediastinum, and cervical spine was identified with a positron emission tomography scan when this patient presented with recurring pneumonias and atrial fibrillation. The presentation and diagnosis were clouded by multiple courses of prednisone and chemotherapy for respiratory complications and metastatic disease, respectively...

Sternal metastases are not studied extensively in the literature. There is a paucity of information on their role in metastatic disease. The concept of the fourth column was described by Berg in 1993, and has been proven in case report, clinically and biomechanical studies. The role of the sternum as a support to the thoracic spine is well documented in the trauma patients, but not much is known about its role in cancer patients. This review examines what is known on the role of the fourth column. Following this we have identified two likely scenarios that sternal metastases may impact management: (1) sternal pathological fracture increases the mobility of the semi-rigid thorax with the loss of the biomechanical support of the sternum-rib-thoracic spine complex; and (2) a sternal metastasis increases the risk of fracture, and while being medical treated the thoracic spine should be monitored for acute kyphosis and neurological injury secondarily to the insufficiency of the fourth column...

BACKGROUND: Spinal metastatic paraganglioma (MPG) is rare and only reported in individual case reports. The low incidence makes it difficult to define appropriate therapy and prognosis. Our study illustrated the largest series to discuss the possible treatment and outcomes of patients with spinal MPG. METHODS: A retrospective study of 15 patients with spinal MPG who were surgically treated between 2005 and 2014 was performed. Three surgical modalities were applied, and radiotherapy and chemotherapy were utilized as adjuvant therapy...

A 74-year-old man with newly diagnosed prostate cancer underwent Ga-PSMA PET/CT, which demonstrated intense uptake in and adjacent the L2 vertebral body. Subsequent MRI of the lumbar spine showed an aggressive L2 hemangioma with adjacent soft tissue extension. There was congruence of the intraosseous and extraosseous components of the hemangioma and the PSMA PET uptake. This is a rare but important potential pitfall in Ga-PSMA PET/CT-a soft tissue lesion with intense tracer uptake related not to a nodal metastasis of prostate cancer but to extraosseous extension of an aggressive vertebral body hemangioma...

Bone metastases are a frequent occurrence with cancer, and early detection can guide the patient's treatment regimen. Metastatic bone disease can present in density extremes as sclerotic (high density) and lytic (low density) or in a continuum with an admixture of both sclerotic and lytic components. We design a framework to detect and characterize the varying spectrum of presentation of spine metastasis on positron emission tomography/computed tomography (PET/CT) data. A technique is proposed to synthesize CT and PET images to enhance the lesion appearance for computer detection...

BACKGROUND: Stereotactic radiosurgery (SRS), a technique that is emerging as a new treatment option, has been reported to be an effective, noninvasive treatment for spine metastasis patients. OBJECTIVE: This nationwide study aimed to understand the current state of SRS for spine metastasis. METHODS: Patients in this study were first diagnosed with a metastatic spine tumor between 1 July and 31 December 2011. One group (the SRS group) received SRS at least once within 1 year of diagnosis and the other (the non-SRS group) did not receive SRS...

The present study aimed to describe the clinical results of re-irradiation (Re-RT) for spine or pelvic bone metastasis at the same initial irradiated area. Between April 2010 and March 2014, cases involving 98 patients with spine or pelvic bone metastasis who had undergone Re-RT at five institutions were reviewed. The clinical outcomes following Re-RT were evaluated, including overall survival (OS) and severe adverse events. The median time interval from initial radiation therapy (RT) to Re-RT was 439 days (range, 23-4,993 days), and the median duration of patient follow-up was 256 days (range, 11-2,284 days)...

The expression and correlation analysis of the regenerating gene family member 4 (RegIV) and vascular endothelial growth factors (VEGF-A and VEGF-C) in metastatic spinal tumors were studied. Fifteen patients with metastatic spinal tumors who underwent operation in our hospital from January 2011 to January 2013 were selected into this study. The expression level of tumor tissues in patients with spinal metastasis and RegIV, VEGF-A and VEGF-C of the corresponding paracancer normal tissue samples were evaluated by immunohistochemical staining method and the correlation between the expression of RegIV, VEGF-A and VEGF-C was analyzed...

A 36 year-old male with no significant past medical history presented with lower extremity numbness, gait instability, and urinary and bowel retention of 4 weeks onset. Spine MRI revealed diffuse oedema of cervicothoracic spinal cord with several solid enhancing intramedullary lesions, suggestive of metastases. The (18)F-FDG PET/CT performed to identify the primary malignancy demonstrated mild hypermetabolic foci within the cervicothoracic cord, as well as a mildly hypermetabolic bilateral hilar lymphadenopathy and a mildly hypermetabolic pulmonary nodule, suggestive of sarcoidosis versus metastasis...

BACKGROUND: Malignant tumours particularly often metastasise to the spine, causing considerable pain and limiting the patient's physical function. Standard therapy consists in surgical treatment with adjuvant radiotherapy. The qualification for surgery is a multifaceted process and detailed analysis of the morphology of the metastasis is a key factor. Numerous types of classification of metastatic lesions exist, among which the Tomita system, based on MRI findings, appears to be the most practical...

BACKGROUND: Malignant peripheral nerve sheath tumor (MPNST) arising in benign schwannoma with multiple intraosseous spinal metastasis is extremely rare, having a highly aggressive progression and poor prognosis. In such cases, the malignant cells of MPNST usually have an epithelioid morphology. Here, the authors present a very rare case of spindle cell type MPNST arising in benign schwannoma. CASE: A 47-year-old woman had a history of wide marginal excision of right buttock spindle cell sarcoma previously...
