Drop metastases from glioblastoma multiforme (GBM) to the spinal cord are extremely rare in clinical practice. We report herewith multiple drop metastases to the cervical and thoracic spinal cord presenting as paraplegia in a patient treated initially with tumor resection followed by chemoradiation and later with temozolomide-.based adjuvant chemotherapy.

A 28-year-old man was hospitalized with advancing paraplegia. Under the diagnosis of Guillain-Barre syndrome, steroid pulse therapy was administered and plasmapheresis was performed. However, the paraplegia gradually progressed. Subsequently, a spinal cord tumor was revealed by magnetic resonance imaging (MRI). The pathological diagnosis, obtained by open biopsy, confirmed a mixed germ cell tumor in the spinal cord. Multiple lung and lymph nodes metastases were also detected upon computed tomography, along with increased serum alpha-fetoprotein (33.9 ng/mL) and human chorionic gonadotropin (182.5 mIU/mL) levels. Consequently, he received chemotherapy comprising three courses of BEP (bleomycin, etoposide, and cisplatin) as first-line therapy, followed by four courses of TGN (paclitaxel, gemcitabine, and nedaplatin) as second-line treatment. As a result, the spinal cord lesion area was significantly decreased and the alpha-fetoprotein and human chorionic gonadotropin levels were normalized. Four years after chemotherapy, MRI revealed pituitary gland and pineal organ recurrence of the germ cell tumor and additional TGN chemotherapy was performed.

Solitary epidural space metastasis of a malignant tumor is rare. We encountered a 79-year-old male patient with solitary metastatic epidural tumor who developed paraplegia and dysuria. The patient had undergone total gastrectomy for gastric cancer followed by chemotherapy 8 months priorly. The whole body was examined for suspected metastatic spinal tumor, but no metastases of the spine or important organs were observed, and a solitary mass was present in the thoracic spinal epidural space. The mass was excised for diagnosis and treatment and was histopathologically diagnosed as metastasis from gastric cancer. No solitary metastatic epidural tumor from gastric cancer has been reported in English. Among the Japanese, 3 cases have been reported, in which the outcome was poor in all cases and no definite diagnosis could be made before surgery in any case. Our patient developed concomitant pneumonia after surgery and died shortly after the surgery. When a patient has a past medical history of malignant tumor, the possibility of a solitary metastatic tumor in the epidural space should be considered.

The occurrence of longitudinally extensive transverse myelitis (LETM) in an elderly patient should evoke search for underlying systemic malignancy. Intramedullary spinal cord metastases and paraneoplastic myelopathy are the most common etiology for LETM in patients with systemic malignancy. The occurrence of LETM in association with renal cell carcinoma with aquaporin-4 (AQP4) antibody positivity has not been reported. We report an elderly woman who presented with acute paraplegia and was diagnosed as having LETM with AQP4 positivity and renal cell carcinoma.

Extraneural metastasis is extremely rare in pediatric patients with high-grade glioma and carries a grim prognosis. Detection of metastases at initial presentation is even rarer. A 15-year-old adolescent girl presented with paraplegia, urinary retention, and a constellation of systemic symptoms. Imaging showed a fourth ventricular lesion, innumerable intradural lesions, leptomeningeal seeding throughout the neuraxis, and numerous osteoblastic lesions involving the spine, ribs, sternum, pelvis, humerus, and femurs. Pathology confirmed metastatic diffuse midline glioma, H3K27M-mutant. Our patient died 2 weeks after initial presentation. Further work is needed to develop effective treatment strategies for these high-risk patients.

Spinal tuberculosis is a common manifestation of extrapulmonary tuberculosis and osteoarticular tuberculosis. Common clinical manifestations include constitutional symptoms, back pain, spinal tenderness, paraplegia, and spinal deformities. They are the common causes of paralysis and could increase the mortality in patients. Most cases of spinal tuberculosis remaining undiagnosed, and early clinical symptoms and imaging manifestations lack specificity, which explained the reason why it is difficult to identify from atypical spinal metastases, brucellosis and other diseases. The rate of missed diagnosis and misdiagnosis for spinal tuberculosis is high. If spinal tuberculosis diagnostic targets could be early detected, the therapeutic targets can be effectively treated, which can not only control the progress of the disease and shorten the course of treatment, but also reduce the economic pressure and avoid spinal deformity. Therefore, early diagnosis should be our focus. Comprehensive use of a variety of diagnostic targets can improve the early diagnosis rate of spinal tuberculosis. Here, we review the progress of laboratory, imaging and gene detection in the diagnosis of spinal tuberculosis in recent years.

Paraganglioma is a neuroendocrine tumor arising from extra-adrenal sites in the peripheral nervous system. Although malignant paraganglioma is known to metastasize to bones, including vertebral bodies, there is little literature on the compressive myelopathy accompanied by sphincter dysfunction; to our knowledge, only 12 cases have been reported. Moreover, neuropathological investigations of the spinal cord in this state have not been well-documented. This autopsy report describes a 55-year-old man with malignant paraganglioma and compression myelopathy caused by vertebral metastasis. The present case showed a gradual numbness and a sudden onset of irreversible paraplegia with sphincter dysfunction, which were not palliated these neurologic dysfunctions despite radiotherapy. Computed tomography (CT) revealed multiple metastases to the bones, lymph nodes, and lungs when he was diagnosed with malignant paraganglioma. At the same time, he had numbness, and magnetic resonance imaging (MRI) showed multiple diffuse metastatic lesions in the vertebral bodies. Following abrupt onset of paralysis, MRI showed fractured third and sixth thoracic vertebral bodies. An autopsy revealed residual vertebral metastases with fractures of the third and sixth thoracic vertebral bodies, resulting in compressive myelopathy at the fourth thoracic segment, which was characterized by complete spinal cord destruction. Destructive spinal cord lesion-induced secondary degeneration was observed in the gracile fasciculus at the rostral side and in the pyramidal tract at the caudal side, which showed Wallerian degeneration. Such pathology was consistent with the presenting neurological symptoms, including paraplegia and somatic sensory loss below the fourth thoracic spinal cord segment. Although it is difficult to identify the pathognomonic morphological changes responsible for the sphincter dysfunction, the present case suggests a supranuclear dysregulation of the somatosensory and central autonomic nervous systems involved in urination and defecation. Based on a review of the literature and the features of the present case, paraganglioma can metastasize aggressively even with a low pathological grading. This case of vertebral metastasis as a result of malignant paraganglioma may not be extraordinary but the autopsy report is rare. This autopsy revealed transverse myelopathy as a result of malignant vertebral metastasis of malignant paraganglioma.

Here, we report a case of spinal tuberculosis without elevation of C-reactive protein (CRP) at the initial visit mimicking spinal metastasis. A 70-year-old woman developed progressive paraplegia without a history of injury and came to our hospital for evaluation. Severe compression to the spinal cord with osteolytic destruction of the spinal vertebrae at T6-7 was observed without elevation of CRP. A T4-9 posterior decompression and fusion were performed. Although the pathology revealed no malignant tumor cells, a positron emission tomography-computed tomography (PET-CT) showed upregulation of the thyroid gland and aspiration cytology revealed a thyroid carcinoma. Thus, we diagnosed her with spinal metastases from thyroid carcinoma. Conservative treatment was chosen with the hope of a significant neurologic recovery; however, 9 months after the primary surgery, she returned to our hospital with reprogressive paraplegia. In addition to progression of osteolytic changes to the T5-7 vertebrae, a coin lesion on the right side of the lung and elevation of CRP were observed. Finally, we diagnosed her with spinal tuberculosis based on the results of a CT-guided needle culture. Two-stage surgeries (posterior and anterior) were performed in addition to administering antituberculosis medications. At the 1-year postoperative follow-up evaluation, both neurologic function and laboratory data were improved with T5-9 complete fusion. It is difficult to determine based on imaging findings alone whether osteolytic vertebrae represent spinal metastases or tuberculosis. Even though inflammatory biomarkers, such as CRP, were not elevated, we should consider the possibility of not only spinal metastases but also tuberculosis when planning surgery involving osteolytic vertebrae. In addition, the combination of neurological, imaging, and pathological findings is important for the diagnosis of spinal tuberculosis.
