Upper Cervical Leiomyoma in an Adolescent Male.

Introduction: Leiomyomas are benign epithelial tumors with a female preponderance usually in the uterus, gastro-intestinal tract and skin. They are well-capsulated tumors with no mitotic activity and little pleomorphism. Primary leiomyoma in the upper cervical spine region is rare and the occurrence of these lesions in young immunocompetent males is extremely rare. Case Report: A 15-year-old male had swelling over the nape of the neck for 4 years with slight difficulty in neck movements for a few months. Asymptomatic 4 years back be developed a painless swelling at the nape of the neck on the right side initially the size of a pea which gradually increased size. A 10x8cm firm, on-tender and non-pulsatile swelling at the nape of the neck on the right extending from the occipital nuchal line and crossing the midline up to the posterior border of the sternomastoid. The skin over the swelling wasn't adherent and the swelling did not reduce on neck movements. Neck movements were terminally restricted with restriction on rotation towards the right. Routine X-ray's and magnetic resonance imaging were suggestive of a soft tissue mass in the inter-muscular plane on the posterior aspect more on the right side with a cystic component and causing thinning of the C2 lamina with no intraspinal extension. Biopsy was done. Findings were suggestive of a spindle cell benign tumor. Posterior en bloc excision was planned and the lesion blog with the entire capsule was excised and sent for histopathology which revealed the lesion was a leiomyoma. The patient has shown no clinical or radiological evidence of recurrence at 4 year fol-low-up. Conclusion: Leiomyomas in the upper cervical spine is extremely rare in adolescent immunocom-petent male.

Aggressive Vertebral Hemangioma Causing Recurring Myelopathy -A Rare Case Report and Review of Literature.

Introduction: Vertebral hemangiomas although benign vascular lesions few of these may be ag-gressive causing osseous, extra-osseous and/or epidural expansions with recurrence rate as low as 3%. It should be considered as one of the important differentials while dealing with lytic lesions in the dorsal spine causing compressive myelopathy. Case Report: A 16-year-old female came with an acute history of paraparesis with bladder in-volvement. She was diagnosed of vertebral hemangioma of D9 for which she underwent surgical decompression and fixation. At present, she had paraparesis with a sensory level of D10 on exami-nation. After radiological investigations (X-ray and MRI) she had high intensity signals in the extra osseous portion of D9 with significant neural compression indicating recurrence of vertebral he-mangioma. She underwent decompression with long segment instrumentation with prior arterial embolization. Histopathology features were suggestive of hemangioma and our diagnosis of recur-rence was confirmed. At 2 weeks, the patient had improved neurology with partial sensory recovery and Grade 2 power in the right lower limb and Grade 1 power in the left lower limb. Histopathology report confirmed the diagnosis of hemangioma indicating recurrence. At 6 months follow-up after aggressive rehabilitation, the patient was spastic and improved to Grade 3 power in the left lower limb and Grade 4 power in the right lower limb. The sphincteric control was also found to be fair at 1 year follow-up. Discussion: Vertebral hemangiomas when causing progressive neurological deficit warrant surgical decompression. The choice of intervention depends on location and extent of the tumor. Due to their high vascularity, it is advisable for to preoperatively carry out arterial embolization. Conclusion: Although commonly asymptomatic, vertebral hemangiomas may present as compressive myelopathy. Therefore, they should be detected early, intervened and followed up regularly to detect recurrence to prevent worsening of neurology and function.

Surgery Versus Radiofrequency Ablation in the Management of Spinal Osteoid Osteomas: A Spine Oncology Referral Center Comparison Analysis of 138 Cases.

BACKGROUND: Osteoid osteomas (OOs) are benign bone forming tumors that, usually, occur in the extremities, with about 10% of them arising in the spine more commonly in the posterior elements. The aim of this study is to evaluate the long-term results of patients suffering from spinal OO treated with surgery and radiofrequency ablation. METHODS: This was a retrospective comparison analysis of data prospectively collected from 2 cohorts of consecutive patients diagnosed with OO of the spine treated at the same Institute from November 2002 to February 2019. The first cohort included patients submitted to an intralesional extracapsular excision of the lesion (surgery group); the second cohort included patients submitted to radiofrequency ablation (RFA group). RESULTS: The surgery group showed a local recurrence rate of 1.7% versus a recurrence rate of 12.5% in the RFA group with a statistically significant difference in the disease-free survival at longest follow-up (P = 0.012). No statistically significant differences were observed in local recurrence rate stratified for level and site of lesion. No complications were observed in both groups at the time of first procedure. CONCLUSIONS: Surgery and RFA are both safe and effective interventional procedures for the management of spinal OO, although RFA is associated with a greater recurrence rate. Treatment should be tailored according to the relationship of lesions with neural structures and to advantages and disadvantages of each technique.

Radial Artery Pseudoaneurysm in a Post-operative Case of Midshaft Radius Fracture.

INTRODUCTION: Pseudoaneurysms of arteries are not uncommon complications of vessel handling during surgery. Early identification and management is important to prevent disastrous complications such as rupture and thrombosis. CASE REPORT: We describe a case of a 28-year-old male who developed a pseudoaneurysm of the radial artery after being operated by plating for a mid-shaft radius fracture. He presented 2 weeks after surgery with swelling over the forearm which was confirmed to be a pseudoaneurysm after computed tomography angiography. It was treated with surgical excision and end-to-end anastomosis. CONCLUSION: A high index of suspicion must be maintained about the occurrence of this complication secondary to both trauma and surgery.
