Case series summary Two cats aged between 1 and 2 years were presented for paraparesis, general discomfort, back pain and urinary retention. Extradural spinal cord compression at the level of T4 and T8 was evident on CT examination and on MRI. Hemilaminectomy and partial corpectomy were performed to achieve spinal cord decompression. Histopathology of the abnormal bone tissue was suggestive of vertebral angiomatosis. After initially worsening, both cats recovered their normal gait and functional urination. Both cats have been followed-up for >1 year, without any recurrence. Relevance and novel information This is the first report of vertebral angiomatosis with complete data (CT, MRI, surgical procedures, histopathology and >1 year follow-up) and provides important information about the prognosis of this rare vascular malformation.

Abstract Thoracic disc herniations are an infrequent occurrence, but can be a cause of significant myelopathy. Diagnosis typically requires a high clinical suspicion that is confirmed with appropriate imaging. Classically, the transthoracic approach for discectomy is the treatment of choice for symptomatic cases. This video concerns a 48-yr-old woman who presented with worsening mid-back pain and progressive gait difficulty. Her examination was significant for proximal lower extremity muscle weakness, difficulty with tandem gait, and urinary incontinence. Imaging demonstrated a large T7-8 disc herniation causing severe spinal cord compression. The patient underwent T7-8 transthoracic discectomy and interbody fusion. She tolerated the procedure well without complication, and postoperative imaging demonstrated decompression of her spinal cord. On follow-up, she had improved mid-back pain, strength, and ambulatory function. The patient consented to the recording of this surgical video for potential publication.

Spinal Cord Decompression

AbstractThis is a retrospective case series in which clinicopathological and imaging findings associated with neurological complications secondary to melarsomine dihydrochloride administration are reported in two dogs with Dirofilaria immitis infection. Following intramuscular injection of melarsomine dihydrochloride based on manufacturers' guidelines, two dogs developed acute, progressive, nonambulatory paraparesis or paraplegia. Magnetic resonance imaging was suggestive of epidural steatitis, resulting in compression of the spinal cord and spinal cord oedema. In one dog, emphysematous myositis throughout the lumbar paravertebral muscles was present. Hemilaminectomy with the intent of achieving spinal cord decompression and obtaining specimens for microbiological and histopathological evaluation was performed in both dogs. One dog partially regained function postoperatively whereas the other was euthanatized intraoperatively. Histologically, epidural steatitis was observed in the surviving dog and epidural steatitis, myonecrosis and grey and white matter changes in the spinal cord were observed in the euthanatized dog. Microbiological testing failed to identify bacteria from the affected tissues. Both cases highlight the potential for the development of extensive epidural steatitis and consequent spinal cord compression following intramuscular administration of melarsomine dihydrochloride. Further investigation into the optimal therapeutic intervention in dogs experiencing neurological complications following melarsomine administration is warranted.

Existen múltiples técnicas para la descompresión medular en la columna torácica, cada una con sus ventajas y desventajas y con distintos requerimientos de destrezas quirúrgicas. Se han desarrollado técnicas mínimamente invasivas que disminuyen las tasas de morbilidad, con buenos resultados funcionales. Se presenta el caso de un hombre de 64 años, con clínica de compresión medular, una hernia de disco central, calcificada a nivel del quinto disco torácico, migrada hasta el borde inferior de la sexta vértebra torácica, con franca compresión medular. Se realizó un abordaje lateral transpleural mínimamente invasivo, con una corpectomía parcial posterior de la sexta vértebra, sin fijación adicional. El paciente tuvo una buena evolución, sin progresión del cuadro neurológico ni dolor costal residual.Los abordajes laterales mínimamente invasivos son técnicas válidas para tratar patologías compresivas de la columna torácica, con bajas tasas de morbimortalidad y una rápida recuperación. AbstractThere are multiple techniques for spinal cord decompression in the thoracic spine, each with its advantages and disadvantages, and requiring different surgical skills. Recently, minimally invasive techniques have been developed, reducing morbidity rates and achieving good functional results.We present the case of a 64-year-old male with spinal compression symptoms, central disc herniation calcified at the fifth thoracic vertebra, which migrated to the lower end of the sixth thoracic vertebra. Diagnosis was clear for spinal cord compression. Partial posterior corpectomy of the sixth vertebra was performed with a minimally invasive transthoracic transpleural lateral approach and without additional fixation. The patient had a good outcome on follow-up, without progression of neurological symptoms or residual rib pain.Minimally invasive lateral approaches are valid techniques for the treatment of compression disorders of the thoracic spine, with low rates of morbidity and mortality, and a rapid recovery.

Background Context.Up to date, only four cases of primary intradural extramedullary spinal cord melanoma (PIEM) have been reported. No previous reports have described a case of PIEM located in the lower thoracic spine with long-term follow-up.Purpose. Demonstrating an unusual, extremely rare case of melanoma manifestation.Study Design. Case report.Methods. We report a case of a 57-year-old female suffering from increasing lower extremity pain, left-sided paresis, and paraesthesia due to spinal cord compression caused by PIEM in the lower thoracic spine.Results. Extensive investigation excluded other possible primary melanoma sites and metastases. For spinal cord decompression, the tumor at level T12 was resected, yet incompletely. Adjuvant radiotherapy was administered two weeks after surgery. The patient was recurrence-free at 104 weeks after radiotherapy but presents with unchanged neurological symptoms.Conclusion. Primary intradural extramedullary melanoma (PIEM) is extremely rare and its clinical course is unpredictable.

Spinal Cord Decompression

Paraplegia is a well-defined state of complete motor deficit in lower limbs, regardless of sensory involvement. The cause of paraplegia usually guides treatment, however, some controversies remain about the time and benefits for spinal cord decompression in nontraumatic paraplegic patients, especially after 48 hours of the onset of paraplegia. The objective of this study was to evaluate the benefits of spinal cord decompression in such patients. We describe three patients with paraplegia secondary to non-traumatic spinal cord compression without sensory deficits, and who were surgically treated after more than 48 hours of the onset of symptoms. All patients, even those with paraplegia during more than 48 hours, had benefits from spinal cord decompression like recovery of gait ability. The duration of paraplegia, which influences prognosis, is not a contra-indication for surgery. The preservation of sensitivity in this group of patients should be considered as a positive prognostic factor when surgery is taken into account.

Interstitial Thermotherapy

OBJECT High-grade malignant spinal cord compression is commonly managed with a combination of surgery aimed at removing the epidural tumor, followed by spinal stereotactic radiosurgery (SSRS) aimed at local tumor control. The authors here introduce the use of spinal laser interstitial thermotherapy (SLITT) as an alternative to surgery prior to SSRS. METHODS Patients with a high degree of epidural malignant compression due to radioresistant tumors were selected for study. Visual analog scale (VAS) scores for pain and quality of life were obtained before and within 30 and 60 days after treatment. A laser probe was percutaneously placed in the epidural space. Real-time thermal MRI was used to monitor tissue damage in the region of interest. All patients received postoperative SSRS. The maximum thickness of the epidural tumor was measured, and the degree of epidural spinal cord compression (ESCC) was scored in pre- and postprocedure MRI. RESULTS In the 11 patients eligible for study, the mean VAS score for pain decreased from 6.18 in the preoperative period to 4.27 within 30 days and 2.8 within 60 days after the procedure. A similar VAS interrogating the percentage of quality of life demonstrated improvement from 60% preoperatively to 70% within both 30 and 60 days after treatment. Imaging follow-up 2 months after the procedure demonstrated a significant reduction in the mean thickness of the epidural tumor from 8.82 mm (95% CI 7.38–10.25) before treatment to 6.36 mm (95% CI 4.65–8.07) after SLITT and SSRS (p = 0.0001). The median preoperative ESCC Grade 2 was scored as 4, which was significantly higher than the score of 2 for Grade 1b (p = 0.04) on imaging follow-up 2 months after the procedure. CONCLUTIONS The authors present the first report on an innovative minimally invasive alternative to surgery in the management of spinal metastasis. In their early experience, SLITT has provided local control with low morbidity and improvement in both pain and the quality of life of patients.

Spinal Meningiomas

Spinal meningiomas are the most common adult primary spinal tumor, constituting 24–45% of spinal intradural tumors and 2% of all meningiomas. The aim of this study was to assess postoperative complications, long-term outcomes, predictors of functional improvement and differences between elderly (≥70 years) and non-elderly (18–69 years) patients surgically treated for spinal meningiomas. Variables were retrospectively collected from patient charts and magnetic resonance images. Baseline comparisons, paired testing and regression analyses were used. In conclusion, 129 patients were included, with a median follow-up time of 8.2 years. Motor deficit was the most common presenting symptom (66%). The median time between diagnosis and surgery was 1.3 months. A postoperative complication occurred in 10 (7.8%) and tumor growth or recurrence in 6 (4.7%) patients. Surgery was associated with significant improvement of motor and sensory deficit, gait disturbance, bladder dysfunction and pain. Time to surgery, tumor area and the degree of spinal cord compression significantly predicted postoperative improvement in a modified McCormick scale (mMCs) in the univariable regression analysis, and spinal cord compression showed independent risk association in multivariable analysis. There was no difference in improvement, complications or tumor control between elderly and non-elderly patients. We concluded that surgery of spinal meningiomas was associated with significant long-term neurological improvement, which could be predicted by time to surgery, tumor size and spinal cord compression.

CONTEXT: Spinal cord compression due to extramedullary hematopoiesis is a well-described but rare syndrome encountered in several clinical hematologic disorders, including <FONT FACE="Symbol">b</font>-thalassemia. CASE REPORT: We report the case of a patient with intermediate <FONT FACE="Symbol">b</font>-thalassemia and crural paraparesis due to spinal cord compression by a paravertebral extramedullary mass. She was successfully treated with low-dose radiotherapy and transfusions. After splenectomy, she was regularly followed up for over four years without transfusion or recurrence of spinal cord compression. DISCUSSION: Extramedullary hematopoiesis should be investigated in patients with hematologic disorders and spinal cord symptoms. The rapid recognition and treatment with radiotherapy can dramatically alleviate symptoms.

BACKGROUND Spinal cord stimulation (SCS) uses unique electric stimulation parameters to selectively treat specific regions of chronic or refractory back pain. Changing these parameters can lead to spreading paresthesia and/or pain beyond the desired region. OBSERVATIONS A patient with a history of stable, successful SCS treatment presented with acute development of paresthesias that were relieved by reduction of stimulation parameters. The patient required paradoxically lower SCS settings for control of chronic back pain. This presentation prompted further investigation, which revealed a new disc protrusion and cord compression at the level of the paddle lead. LESSONS In patients with SCS, a new onset of back pain accompanied by acute paresthesia that is reversible by reducing the SCS amplitude warrants investigation for new spine pathology.

✓ This is an analysis of 10 cases of dermoid tumor occurring in the spinal canal (8 lumbar and 2 thoracic). Low-back pain was the commonest presenting symptom, especially if the tumor was adherent to the conus medullaris. Other complaints included urinary dysfunction and motor and sensory disturbances of the legs. Clinical and radiological evidence of spina bifida was found in about half of the cases and suggested the diagnosis of a developmental type of tumor when patients presented with progressive spinal cord compression. At operation, the tumors were often found embedded in the conus medullaris or firmly adherent to the cauda equina, thus precluding complete removal. Evacuation of the cystic contents, however, gave lasting relief of the low-back pain and did not cause any deterioration in neurological function. In a follow-up study, ranging from 1 to 15 years, virtually no improvement in the neurological signs was observed. On the other hand, only one case has deteriorated due to recurrence of tumor growth.
