The case report presents the clinical, clinicopathological, diagnostic imaging and histopathological findings of spinal cord nephroblastoma in a dog. It was admitted with a 2-week history of a “weight-bearing” lameness of the left posterior limb that evolved to paraplegia within hours. Neurological examination showed spastic paraplegia compatible with a T3-L3 spinal cord lesion. Differential diagnosis included ischemic myelopathy, myelitis and acute spinal cord compression. The spinal radiographs and cerebrospinal fluid analysis were unremarkable. Cisternal myelography indicated a focal intradural-extramedullary lesion at the level of T12 vertebra. Further diagnostic investigation was not performed because the owner decided to proceed to euthanasia. Histopathological examination of the spinal cord confirmed the diagnosis of intraspinal nephroblastoma.

Case summary A 2-year-old neutered female Scottish Fold cat was presented with an 8-week history of progressive back pain, paraparesis and decrease of postural reactions in both pelvic limbs. MRI showed spinal cord compression from both ventral sides, which originated from the T4 vertebral body and pedicle. The lesion compressing the spinal cord had a bone-like density on CT, and endoscopic surgery was performed to excise it. Histopathological examination of the resected tissue showed no evidence of malignancy and the lesion was diagnosed as vertebral hypertrophy. After surgery, the neurological status of the cat gradually improved. The cat was ambulant at the follow-up evaluation 2 weeks after surgery. Six months later, hindlimb paresis had improved considerably, and no recurrence was observed on CT. Relevance and novel information This is the first description of thoracic vertebral canal stenosis due to hypertrophy of a single vertebra in a young cat. Excision of the hypertrophic vertebra by endoscopic surgery is less invasive than open surgery and may give a good prognosis.

Intradural Extramedullary

Background: Intradural extramedullary tuberculoma of the spinal cord (IETSC) is an extremely rare form of spinal tuberculosis (TB) that is believed to be due to a host’s immune reaction against the Mycobacterium protein derivatives. Case Description: A 25-year-old male with human immunodeficiency virus, hepatitis C virus, and disseminated TB on antitubercular therapy for the past 8 months, presented with paraplegia of 2 months duration. When the MRI spine revealed multiple peripheral rim enhancing intradural extramedullary lesions from T6 to T8 and dorsally from T10 to T11, the patient was diagnosed with IETSC. At surgery, we countered cystic lesions adherent to the dura and the spinal cord, containing a whitish material. Postoperatively, the patient showed clinical improvement in motor power and sensation. Conclusion: Intradural extramedullary spinal tuberculomas in patients with a history of TB and spinal cord compression, although rare, should be considered among the differential diagnoses.

Abstract Arachnoid web of the spine (AWS) is a rare and subtle lesion that can have severe neurological consequences. Patients typically present with progressive myelopathic symptoms and have no more than a slight indentation of spinal cord on imaging, commonly referred to as the “scalpel sign.” A unique feature associated with this lesion is the extent of (and sometimes the rapidity of) the recovery that occurs following treatment. In this operative video, we highlight the treatment of a 32-yr-old male with a history of lumbar spondylosis, who, over a 2 wk period, developed progressive spasticity and weakness of the entire left lower extremity and left foot numbness. Magnetic resonance imaging revealed a T4-T5 “scalpel sign” and spinal cord compression on computed topography myelogram, which was subsequently taken to the operating theater. The major steps in this video include the following: A) a summary of the patient's presentation and preoperative imaging, B) the technical steps in the surgical lysis of the AWS, and C) his postoperative course. The patient tolerated the procedure well, demonstrating a rapid improvement in symptoms postoperative day 1. At the time of most recent follow-up (4 mo), the patient remains neurologically intact with a full return to his neurologic baseline. Surgical lysis of AWS demonstrated to be a curative procedure with rapid neurological recovery, showing no signs of recurrence or regression. Consent was given by the patient for the use of deidentified images and the intraoperative video for educational purposes at the time consent was obtained for the surgical procedure, in accordance with our institution's policy.

Extraosseous Ewing’S Sarcoma

An immunocompetent 47-year-old man presented with a five-month history of progressive lower limb weakness, back pain, sphincter dysfunction, and intermittent fever, suggesting myelopathy in a chronic deteriorating course. A comprehensive analysis comprising of blood tests, neuroimaging, CSF profiling, molecular analysis, and histopathology was performed. Notably, enhanced spinal cord MRI revealed longitudinally extensive intradural-extramedullary lesions involving the cervical, thoracic, and lumbosacral spinal cord, with homogeneous enhancement and spinal cord compression. Serum TPHA and RPR tests were positive. CSF profiling showed pleocytosis, significant protein elevations, hypoglycorrhachia, and positive TPHA test. 18F-FDG-PET/CT indicated slightly increased intraspinal FDG uptake. Spinal cord biopsy further showed small round blue cells in poorly differentiated tissues. Immunostaining was positive for NKX2.2, CD56, CD99, Synaptophysin, and Ki67 (50%). Molecular analysis detected a novel MALAT-CYSLTR1 fusion protein and variants in oncogenic genes including PTCH1, TERT, CREBBP, SPEN, and STK11. The diagnosis of intraspinal extraosseous Ewing’s sarcoma (ES) was confirmed. Briefly, our case details the diagnosis of a patient with intradural-extramedullary ES and highlights the value of spinal cord biopsy in progressive myelopathy of unknown causes.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

Rotatory Subluxation

The authors present a case report of a patient discovered to have a rotatory subluxation of the C1–2 joint and a large retroodontoid pannus with an enhancing lesion in the odontoid process eventually proving to be caused by gout. This patient represented a diagnostic conundrum as she had known prior diagnoses of not only gout but also sarcoidosis and possible rheumatoid arthritis, and was in the demographic range where concern for an oncological process cannot fully be ruled out. Because she presented with signs and symptoms of atlantoaxial instability, she required posterior stabilization to reduce the rotatory subluxation and to stabilize the C1–2 instability. However, despite the presence of a large retroodontoid pannus, she had no evidence of spinal cord compression on physical examination or imaging and did not require an anterior procedure to decompress the pannus. To confirm the diagnosis but avoid additional procedures and morbidity, the authors proceeded with the fusion as well as a posterior biopsy to the retroodontoid pannus and confirmed a diagnosis of gout.

Abstract This 3-dimensional operative video illustrates resection of 2 cervical spine schwannomas in a 19-yr-old female with neurofibromatosis type 2. The patient presented with lower extremity hyperreflexity and hypertonicity. Magnetic resonance imaging (MRI) demonstrated 2 contrast-enhancing intradural extramedullary cervical spine lesions causing spinal cord compression at C4 and C5. The patient underwent a posterior cervical laminoplasty with a midline dural opening for tumor resection. Curvilinear spine cord compression is demonstrated in the operative video. After meticulous dissection, the tumors were resected without complication. The dural closure was performed in watertight fashion followed by laminoplasty using osteoplastic titanium miniplates and screws. Postoperative MRI demonstrated gross total resection with excellent decompression of the spinal cord. The postoperative course was uneventful. The natural history of this disease, treatment options, and potential complications are discussed.
