“…19,23 Although our cat demonstrated a favourable outcome with medical management, the clinician should be aware of late-onset complications in patients with central nervous system (CNS) foreign body diseases. Migration of foreign bodies, 13,24,25 inflammatory reactions like granuloma [26][27][28][29][30] and abscess formation, [31][32][33] myelitis, 34 arachnoiditis with and without subsequent subarachnoid diverticula or syrinx formation 35,36 and CSF leakage 37 have been reported in veterinary and human medicine. In our cat, some degree of migration of the microchip was identified on follow-up CT that might have occurred in the context of maturing of the spine.…”

Case summary A 15-week-old male British Shorthair cat was presented for peracute paralysis immediately after microchip implantation. Neurological examination revealed a non-ambulatory tetraparesis and left thoracic limb plegia localised to C1–C5 spinal cord segments. CT of the cervical spine showed a diagonally orientated metallic foreign body (microchip transponder, 10 mm in length) within the vertebral canal at the level of C1–C2, resulting in a penetrating spinal cord injury. Based on concerns about further iatrogenic spinal cord injury through surgery, medical management was chosen. Despite the severe clinical signs, the kitten returned to ambulation within 6 days of the injury, with controlled urination and defecation. Continuous neurological improvement was seen for up to 6 weeks after the injury at which point a mild-to-moderate ambulatory tetraparesis and ataxia remained, with an overall good quality of life. Follow-up CT at the age of 13 months revealed a relative cranial displacement and rotation of the microchip towards the foramen magnum, while the cat’s neurological status was unchanged. Relevance and novel information This case demonstrated a cervical penetrating spinal cord injury in a growing cat caused by a microchip, which was successfully managed with medical treatment, suggesting that this might be an option for patients at risk of severe surgery-related complications or where owners reject surgery.

“…There are various reports of vertebral artery foreign bodies that necessitated open approaches for removal and which resulted in significant morbidity. 3,4 One case report described vertebral artery disruption and subsequent mortality. 5 The high location of the foreign in our case made it difficult to access even from an external open approach.…”

Transoral endoscopic approach to upper cervical spine migrated foreign bodies

Background Migrated ingested foreign bodies in the aerodigestive tract can lodge within vital organs and vessels, causing potentially devastating complications. It is often difficult to localise these foreign bodies, with extrication resulting in the requirement for open approaches which may cause significant morbidity. Case report This paper presents the case of an ingested migrated stingray bone lodged adjacent to the vertebral artery in the upper cervical spine. This was managed via an endoscopic transoral approach, with the assistance of an image-guidance system. Results Successful extraction of the foreign body was achieved, with minimal residual morbidity. Conclusion Our study showed that image-guided endoscopic surgery is a safe, precise and feasible option for the localisation and removal of migrated foreign bodies in the aerodigestive tract involving critical neurovascular structures.

“…Basivertebral foramen (BF) is a bone defect in the posterior wall of vertebral body (VB), between the pedicles, containing basivertebral veins, arteries and nerves (Figure 1). BF existed in every vertebra of the spine (1)(2)(3)(4)(5). It has a bigger size than other vessel passage of bone (6).…”

BackgroundBasivertebral foramen (BF) is a vessel and nerve passage in the posterior wall of vertebral body (VB). Our goal was to report BF's morphological characteristics in different age groups of mainland Chinese adults and to evaluate the relationship between BF's morphology and factors such as age, gender, heavy work, size and level of VB.MethodsWe enrolled 300 adults among persons who came to our hospital for health examination. We measured BFs and VBs’ parameters on T1 weighted sagittal lumbar spine MR images. We also assessed following potential predictors: gender, body height, body weight, body mass index, alcohol use, habits of smoking and drinking, type of work (physical work or non-physical work). A stepwise multivariate linear regression analysis was conducted to identify predictors of BF's height.ResultsPeople above 60 have significantly bigger BFHr than those in young adulthood and in the middle ages at all five levels, while they have shallowest BFs, especially at L3. Multiple linear regression resulted in a formula that accounted for 30.1% of the variability in the height of basivertebral foramen. Significant predictors included: gender, age, level, vertebral height and heavy work.ConclusionAge is the highest weight in all factors on the height of BF. BF is closer to the upper endplate. The BF was relatively higher and deeper in the female lumbar spine. Heavywork results in lower BF. Last but not the least, as we supposed, BF gets shallower and higher compare to VB with age.Level of evidencePrognostic level III. See instructions for authors for a complete description of levels of evidence.
