Article Abstract
Background: Mucopolysaccharidosis type VI (MPS VI) is an autosomal recessive lysosomal genetic storage disorder caused by the accumulation of glycosaminoglycans in tissues and organs. A 10-month-old male with MPS VI had originally undergone foramen magnum decompression (FMD)/C1 followed by lifelong enzyme replacement therapy (ERT). At age 15, the patient underwent successful surgical treatment for retro-odontoid disease and recurrent cranio-cervical junction (CCJ) stenosis through a C1-C3 laminectomy and expansive duroplasty.
Case Description: A 10-month-old male with MPS VI and brain stem/spinal cord compression originally underwent a cervical FMD/C1 laminectomy. Despite ERT administration, signs of gait disturbances and myelopathy recurred before 1 year of age. At age 15, both computed tomography and magnetic resonance imaging revealed a retro-odontoid mass causing foramen magnum stenosis/upper cervical cord compression. Following an extended FMD that included a C1-C3 laminectomy and expansive duroplasty, his gait disturbance gradually improved.
Conclusion: Patients with MPS VI may experience recurrent CCJ stenosis and spinal cord compression despite the early initiation of ERT.

Spinal cord compression as the initial presentation of de novo metastatic testicular seminoma: A rare and complex case.

We report a 43-year-old man with de novo metastatic testicular seminoma complicated by paraplegia from spinal cord compression due to retroperitoneal lymphadenopathy. Urgent retroperitoneal biopsy confirmed seminoma and, after the patient declined neurosurgical intervention, systemic chemotherapy was promptly initiated prior to delayed orchidectomy. Post-chemotherapy orchidectomy histology revealed minimal viable tumour and serial imaging showed a residual retroperitoneal mass with low-grade uptake on FDG-PET.

Background: Animal models of nerve compression have revealed neuroinflammation not only at the entrapment site, but also remotely at the spinal cord. However, there is limited information on the presence of neuroinflammation in human compression neuropathies. The objectives of this study were to: (1) assess which tracer kinetic model most optimally quantified [C]DPA713 uptake in the spinal cord and neuroforamina in patients with painful cervical radiculopathy, (2) evaluate the performance of linearized methods (e.

Objective: The purpose of this study is to present five new cases of congenital absence of posterior elements of the axis (C2), totaling 17 cases report in the literature, and to propose an anatomical classification system for this rare condition for standardizing its management.
Methods: A retrospective review of five patients diagnosed and surgically treated for the absence of C2 posterior elements was conducted from 2017 to 2024. Clinical characteristics were summarized, and imaging studies, including X-rays, CT, and MRI were performed to define abnormalities and cord compression.
