Butterfly vertebra is an uncommon congenital spinal anomaly. Only a small number of cases with butterfly vertebra have thus far been reported in the literature.We herewith describe a 32-year-old male admitted to our clinic with low back pain. He has been suffering from low back pain since early adolescence. Radiologic investigations confirmed presence of butterfly vertebra at Lumbar(L)2 level and L3-4, L4-5 posterior disc protrusion and slight osteoarthritic changes in lumbar spine which proved to be a coincidental finding along with nonspecific low back pain. Routine examination of the motor and sensory system was found to be normal. Hematologic evaluation was made to rule out pathologic causes of anterior wedging of the vertebra like infections and metastases in the spine. Butterfly vertebra anomaly is considered to be incidental and usually asymptomatic. Awareness of this anomaly is important for correct diagnosis, while its imaging features may be confused with traumatic compression fracture, or with a pathologic fracture. Also, this spinal anomaly may be associated with many syndromes. This taken into account, all the necessary investigations should be carried out for purposes of achieving a correct diagnosis.

A 66-year-old man was referred to our hospital because of a two-week history off ever and low back pain. There was a hard anal mass on rectal examination. Colonoscopy and computed tomography showed anal adenocarcinoma, multiple metastases to lymph nodes and bones. Blood test showed severe disseminated intravascular coagulation (DIC). Microscopic examination of the bone marrow aspirate revealed disseminated carcinomatosis of the bone marrow. Systemic chemotherapy (mFOLFOX6) was started, then remission of DIC and shrinkage of the tumor were observed. Although the patient had cerebral infarction during the first course of chemotherapy, he received nine courses of treatment. He died six months later because of cerebellar hemorrhage.

Cancer patients with bone metastases are at risk of a variety of skeletal events, including vertebral compression and pathologic fractures. Approximately 30% to 40% of patients with advanced lung cancer will develop bone metastases in the course of their disease, resulting in a significant negative impact on both morbidity and survival. Skeletal complications of bone metastases include pain, pathologic fractures, spinal cord compression, and hypercalcemia. The spine is the most frequent site of skeletal metastases. We present a 48-year-old female with intractable and incapacitating low back pain because of metastatic bone tumor in the left lateral side of S1 and S2 with left sacroiliac invasion. Imaging identified a metastatic invasion of the sacrum. Percutaneous sacroplasty, a safe and effective procedure for sacral-insufficient fractures, was performed under fluoroscopy guidance. However, the expected pain relief was not achieved. At 1 month, the patient remained invalided by severe back pain, which was localized to the left sacroiliac joint. In a second procedure, the sacroiliac joint was cemented. Pain relief was complete, immediate, and sustained until the patient's death related to the underlying oncologic disease. No complications were observed. Few reports exist about the treatment of sacral metastatic tumors with percutaneous sacroplasty. Further, no previous reports about sacroiliac joint cementation for joint stabilization have been found. In the present case, sacroiliac joint cementation successfully resolved residual pain that remained despite percutaneous sacroplasty treatment of the pathologic sacral fracture.

We are presenting a case of a 58-year-old-male patient with a congenital hypoplasia of the lower portion of his left psoas muscle. This rare anomaly, which should be differentiated from other pathological conditions (destructive processes, tumors, metastases, inactivate atrophy), was discovered during the MRI examination of his lumbosacral (LS) spine which the patient underwent due to deterioration of chronic low back pain. His right psoas muscle was hypertrophic. CT examination of his abdomen has shown the identical finding. The MRI examination of his LS spine has shown the intensive and extensive degenerative changes. Besides the hypoplasia of the lower portion of his left psoas muscle, the radiological examinations of the LS spine (MRI) and abdomen (CT) have not shown any other congenital anomalies. Taking into consideration the patient history, the clinical finding, the results of the radiological and other examinations (EMNG) as well as the well known facts about psoas muscle anatomy and function (a stabilizer of the lumbar spine, pelvis and hip; the hip and trunk flexor; the lateral trunk flexor), in this case report, we analysed the clinical manifestations (lateral deviation of lumbar spine; pelvic asymmetry--elvic torsion; increased hip extension on the side of the hypoplastic psoas muscle) and also the late consequences of the unilateral hypoplasia of the psoas muscle (unilateral hypoplasia of the psoas muscle--the overloading of the LS spine and the other psoas muscle--the chronic low back pain--the compensatory hypertrophy of the other psoas muscle-->the intensive and extensive degenerative changes of the LS spine).

Melorheostosis is a rare but benign disorder characterized by asymmetric osteosclerotic dysplasia. Radiographic appearances are characteristic and described as "melting wax flowing down a candle." This disorder may involve more than one bone contiguously across the joints following a sclerotomal distribution. It is often asymptomatic but occasionally presents with pain and contractures. The authors report accidental detection of bilateral upper and lower limb melorheostosis in an elderly woman with the history of breast cancer and recent onset of low back pain, which was referred for a bone scintigram for suspected metastases. The images showed bilateral femoral and tibial melorheostosis, which was subsequently confirmed on plain radiograph and by clinical follow-up.

This report describes the first case of a pregnant woman presenting low-back pain and breast pain associated with bilateral erythematous breast hypertrophy, proving to be the result of metastatic disease from a gastric carcinoma. A 30-year-old pregnant woman was admitted complaining of persistent severe low back pain, breast pain and concomitant bilateral erythematous breast hypertrophy, mimicking primary inflammatory breast carcinoma. During the caesarean section, widespread disease was found and finally metastatic gastric cancer was detected. Pregnant women with gastric cancer may present symptoms that are considered common during pregnancy. Common symptoms that present warning characteristics, such as the persistent severe pain observed in the presented case, should be carefully investigated as they may be the only warning signs and symptoms of rare ominous conditions such as gastric cancer.

Primary spinal melanomas are extremely rare lesions. In 1906, Hirschberg reported the first primary spinal melanoma, and since then only 40 new cases have been reported. A 47-year-old man was admitted suffering from low back pain, fatigue and loss of body weight persisting for three months. He had a 17-year-old history of an operated primary spinal melanoma from T7-T9, which had remained stable for these 17 years. Routine laboratory findings and clinical symptoms aroused suspicion of a metastatic disease. Multislice computed tomography and magnetic resonance imaging revealed stage-IV melanoma with thoracic, abdominal and skeletal metastases without the recurrence of the primary process. Transiliac crest core bone biopsy confirmed the diagnosis of metastatic melanoma. It is important to know that in all cases of back ore skeletal pain and unexplained weight loss, malignancy must always be considered in the differential diagnosis, especially in the subjects with a positive medical history. Patients who have back, skeletal, or joint pain that is unresponsive to a few weeks of conservative treatment or have known risk factors with or without serious etiology, are candidates for imaging studies. The present case demonstrates that complete surgical resection alone may result in a favourable outcome, but regular medical follow-up for an extended period, with the purpose of an early detection of a metastatic disease, is highly recommended.

Cutaneous metastasis of renal cell carcinoma (RCC) is very rare. The author herein report two cases of RCC with cutaneous metastasis. Case 1: is a 75-year-old man with right lumbago. Imaging modalities including CT and MRI revealed a right renal tumor. Nephrectomy was performed. Pathological diagnosis of the renal tumor was RCC of clear cell type (Fuhrman's grade II). He denied follow-up. Nine years later, he (at the age of 84 years), a neck skin tumor emerged. Clinical diagnosis was hemangioma. Imaging modalities including CT and MRI showed several tumors in both lungs. The resection of the neck tumor was performed. The tumor was composed of clear cell type arranged in a trabecular pattern. Immunohistochemically, the tumor cells were positive for pancytokeratins, cytokeratin 18, CD10, Ki-67 (labeling=13%), but negative for CD34, factor-VIII-related antigen, CEA, EMA, melanosome (HMB45), S100 protein, p53, and HepPar-1. Metastatic RCC was diagnosed. Despite interferon therapy, he died of 6 months after the second admission. Case 2 is a 66-year-old man with gross hematuria. Imaging modalities revealed left renal tumor. A nephrectomy was performed. The pathological diagnosis was RCC of clear cell type (grade II). The tumor was invasive into the renal pelvis. He was treated by chemoradiation, but metastases of lungs, skin (thigh), and lib emerged, and died of cachexia 9 months after the admission. Necropsy of the skin tumor was performed. The skin tumor was composed of clear cells arranged in a trabecular pattern. Immunohistochemically, the tumor cells were positive for pancytokeratins (AE1/3, CAM5.2), CD10, p53, and Ki-67 (labeling=20%), but negative for CD34, factor-VIII-related antigen, CEA, melanosome (HMB45), S100 protein, and HepPar-1. A diagnosis of RCC (grade II) was diagnosed.

This article describes a rare malignant spinal tumor successfully treated with total en bloc spondylectomy via a posterior approach. The purpose of this study was to emphasize the occurrence of primary histiocytic sarcoma in the lumbar spine. Histiocytic sarcomas are rare, malignant neoplasms of the lymphohematopoietic system that usually occur in the skin, lymph nodes, and intestinal tracts. Primary spinal column histiocytic sarcoma is rare. To the authors' knowledge, no reports have been published of treating this tumor with total en bloc spondylectomy.A 27-year-old woman presented with a 2-month history of intermittent low back pain and right lower extremity pain. Magnetic resonance imaging and computed tomography (CT) revealed a lumbar vertebra tumor. Positron emission tomography/CT showed focal accumulation in the tumor site. The patient was diagnosed with a histiocytic sarcoma based on biopsy findings and underwent total en bloc spondylectomy of L3 and reconstruction via a posterior approach. The patient maintained normal neurologic function, and the pain was lessened. No major complications occurred. No radiotherapy or chemotherapy was administered postoperatively, and no local tumor recurrence or distant metastases existed at 2-year follow-up.The diagnosis of histiocytic sarcoma relies predominantly on the verification of histiocytic lineage and the exclusion of other, poorly differentiated, large-cell malignancies by immunohistochemical stain. Total en bloc spondylectomy at L3 via a posterior approach can be performed safely and is an important approach in the treatment of selected spinal tumors.

This case series describes and illustrates three cases of sclerotic osseous metastases from untreated renal cell carcinoma (RCC). RCC is commonly metastatic to the skeleton but almost always produces lytic metastases, with only three prior reports of sclerotic metastases identified in the literature. Sclerotic metastasis causing low back pain was the initial disease presentation in two of the three patients in this case series and the first manifestation of metastatic disease in one. The most common metastatic sites of RCC, i.e., retroperitoneal lymph nodes, lung, and liver, were not identified in any of the cases, and skeletal involvement with epidural extension was the only site of metastasis in two. Pathologic specimens from all three cases revealed RCC of high nuclear grade.
