✓The authors describe a precise surgical technique in which a large intraspinal and extraspinal, multivertebral, cervical chordoma was completely removed in one stage using the lateral approach. The patient in this case was a 29-year-old woman who presented with signs of radicular pain in the left C-3 area. Computed tomography and magnetic resonance imaging demonstrated a large intra- and extraspinal multivertebral tumor from C-2 to C-5, a finding that suggested a cervical chordoma. The tumor was completely removed in one stage using the lateral approach while controlling the vertebral artery (VA), and a partial corporectomy of C2–5 was also performed. Results from a postoperative histopathological examination confirmed that the tumor was a typical chordoma. The patient’s postoperative course was uneventful. Cervical chordomas are typically excised using a posterior–anterior surgical approach with partial resection of the tumor. The lateral approach was appropriate in this patient for complete resection in one stage, because it enabled the surgeons to control the VA and access both extraspinal and intraspinal components of the chordoma.

Intramedullary Lesion

Symptomatic intramedullary arachnoid cysts are rare, especially in children; these lesions are rarely described as a cause of spinal cord compression in this age group. The authors report on an 18-month-old boy who experienced a sudden loss of his ability to stand and walk due to a paraparesis. Magnetic resonance imaging of the spine exhibited a cystic intramedullary lesion at the level of T5–6. A hemilaminectomy was performed, and after myelotomy the cystic lesion was decompressed by fenestration to the subarachnoid space. The histopathological examination verified the diagnosis of an arachnoid cyst. In the postoperative course the boy experienced complete resolution of the initial paraparesis.

Brainstem Cavernous Malformation

Removal of brainstem cavernous malformation remains a surgical challenge. We present a case of a 63-year-old female who was diagnosed with a large cavernoma located in the medulla oblongata. The patient suffered three episodes of brainstem bleeding resulting in significant neurological deficits (hemiparesis, dysphagia, and dysarthria). It was decided to remove the cavernoma through a left-sided modified far lateral approach.3The operative video demonstrates the surgical steps and nuances of a complete removal of this complex medulla oblongata cavernous malformation. Total resection was achieved without complications. Postoperative MRI revealed no signs of residual cavernoma with clinical improvement.The video can be found here: https://youtu.be/BTtMvvLMOFM.

Differential diagnosis of globus sensation in an otherwise asymptomatic patient should include hypopharyngeal fibrovascular polyp to avoid potentially fatal complications like airway compromise following regurgitation. We present a case of a 74-year-old man with a 13-cm long hypopharyngeal fibrovascular polyp with 9 months history of globus sensation. A narrow stalk of the giant polyp allowed endoscopic removal and complete resection with the CO2 laser. Histopathological examination was conclusive for the fibrovascular polyp.

Nasosinus metastases from kidney cancer are an unusual clinical presentation although some cases are reported in the literature. Among these cases, sphenoidal metastases are even rarer. Here we report a case of lone sphenoid metastasis in patients with papillary renal cell cancer. Eight months after radical nephrectomy, the patient presented with progressively worsening diplopia. Magnetic resonance imaging showed a mass in the right sphenoid sinus. Histopathological examination of the biopsy sample confirmed diagnosis of sinonasal metastasis from papillary renal cell carcinoma. The patient was declined for surgical management and received stereotactic body radiation therapy. Reassessment MRI at 4 months showed a complete response of the treated sphenoid lesion.

Cardiac calcified amorphous tumors are rare non-neoplastic intracavitary masses with unknown cause. A 60-year-old man presented with sustained ventricular tachycardia. Transthoracic echocardiography and contrast-enhanced angio-computed tomography demonstrated an expanding 73 × 40 mm sized calcified mass in the left ventricle. He underwent successful total removal of the mass and cryo-ablation at the normal myocardial border. Histopathological examination confirmed a diagnosis of cardiac calcified amorphous tumors. The postoperative course was uneventful, without ventricular tachycardia recurrence. To our knowledge, this is the first reported case of confirmed cardiac calcified amorphous tumors causing ventricular tachycardia and treated by surgical resection combined with cryo-ablation.

Primary intracerebral manifestation of multiple myeloma is rare and usually arises from the meninges or brain parenchyma. The authors present a case of multiple myeloma primarily manifesting within the lateral ventricle. A 67-year-old man was admitted with headache accompanied by slowly progressing right hemiparesis. Magnetic resonance imaging showed a large homogeneous contrast-enhancing intraventricular midline mass and hydrocephalus. The tumor was completely resected, and histopathological examination revealed plasmacytoma. After postoperative radio- and chemotherapy, vertebral osteolysis was detected as a secondary manifestation of multiple myeloma.

AbstractObjective:To assess the efficacy of excision of nasal dermoids through a closed rhinoplasty incision. This is the first description of the use of this approach for excision of superficial nasal dermoids.Methods:Three boys aged five, nine and 12 years presented with midline nasal dermoids with minimal cutaneous involvement. Magnetic resonance imaging demonstrated distinct, cystic, superficial nasal masses. The cysts were excised through a closed rhinoplasty approach. In each case, completeness of extirpation was judged by histopathological examination of the excised specimen. Aesthetic outcome was recorded photographically.Results:All three patients' cysts were completely excised, with excellent cosmetic results.Conclusions:The closed rhinoplasty incision is another approach in the surgeon's armamentarium for excision of small, superficial nasal dermoid cysts. In well selected cases, this approach gives optimal cosmetic results, provides adequate exposure with minimal dissection, and allows total extirpation.

Petroclival Meningiomas

Introduction: Petroclival meningiomas constitute 3 to 10% of meningiomas of the posterior fossa, they originate in the petroclival fissure, in the upper part of the clivus, petrosal apex, and medial to the trigeminal nerve. Resection of these tumors is a neurosurgical challenge. The combined partial petrosectomy approach associated with a sub-temporal approach is a technique described by various authors; however, its performance is considered highly complex. We report the case of a petroclival meningioma operated successfully in our hospital using a combined presigmoid and subtemporal transtentorial transpetrosal approach. Clinical case: 33-year-old female patient with a clinical picture of headache, nausea, and gait disturbance. Brain magnetic resonance imaging showed a large right petroclival tumor (4.2x3.9x3.8cm) that displaced the brainstem and secondary hydrocephalus. The hydrocephalus was treated with a ventricular peritoneal shunt. Then, the tumor was resected using a combined presigmoid and subtemporal transpetrosal approach, a technique that allowed adequate exposure of the tumor, achieving complete resection, without intraoperative complications. Postoperative evolution was favorable, with no sequelae. Conclusion: The combined presigmoid and transtentorial subtemporal transpetrous approach for petroclival meningiomas is an effective and feasible technique to perform in our environment. The support of technology such as Neuronavigation, the ultrasonic aspirator, intraoperative monitoring, and adequate experience in skull base surgery are fundamental factors for the success of this surgery.

Abstract OBJECTIVE The influence of the degree of resection on survival in patients with glioblastoma multiforme is still under discussion. The highly controlled 5-aminolevulinic acid study provided a unique platform for addressing this question as a result of the high frequency of “complete” resections, as revealed by postoperative magnetic resonance imaging scans achieved by fluorescence-guided resection and homogeneous patient characteristics. METHODS Two hundred forty-three patients with glioblastoma multiforme per protocol from the 5-aminolevulinic acid study were analyzed. Patients with complete and incomplete resections as revealed by early magnetic resonance imaging scans were compared. Prognostic factors that might cause bias regarding resection and influence survival (e.g., tumor size, edema, midline shift, location, age, Karnofsky Performance Scale score, National Institutes of Health Stroke Scale score) were used for analysis of overall survival. Time to reintervention (chemotherapy, reoperation) was analyzed further to exclude bias regarding second-line therapies. RESULTS Treatment bias was identified in patients with complete (n = 122) compared with incomplete resection (n = 121), i.e., younger age and less frequent eloquent tumor location. Other factors, foremost preoperative tumor size, were identical. Patients without residual tumor survived longer (16.7 versus 11.8 mo, P < 0.0001). In multivariate analysis, only residual tumor, age, and Karnofsky Performance Scale score were significantly prognostic. To account for distribution bias, patients were stratified for age (>60 or ≤60 yr) and eloquent location. Survival advantages from complete resection remained significant within subgroups, and age/eloquent location were no longer unevenly distributed. Reinterventions occurred marginally earlier in patients with residual tumor (6.7 versus 9.5 mo, P = 0.0582). CONCLUSION Treatment bias was demonstrated regarding resection and second-line therapies. However, bias and imbalances were controllable in the cohorts available from the 5-aminolevulinic acid study so that the present data now provide Level 2b evidence (Oxford Centre for Evidence-based Medicine) that survival depends on complete resection of enhancing tumor in glioblastoma multiforme.

An 11-year-old male Rough collie was submitted with paraparesis, but did not respond to medical treatment. Clinical signs worsened and the dog displayed paralysis, inability to stand and loss of voluntary bladder control, whereupon magnetic resonance imaging (MRI) was performed. No significant abnormalities were identified from MRI, blood tests, cerebrospinal fluid tests or radiography. After MRI, the dog developed dyspnoea and died. Autopsy and subsequent histopathological examination led to a diagnosis of degenerative myelopathy.
