Schwannoma of the Tentorium Cerebelli in a Child

Intracranial schwannomas not arising from a cranial nerve are very rare. Schwannomas of the dura are even rarer; in the literature, we found only two cases: a schwannoma of the falx and one of the torcula. We report a third case of a 9-year-old girl with a schwannoma of the tentorium cerebelli. The different theories concerning the origin of this tumor in this particular location are discussed.

For newly diagnosed glioblastomas treated with resection in association with the standard combined chemoradiotherapy, the impact of Carmustine wafer implantation remains debated regarding postoperative infections, quality of life, and feasibility of adjuvant oncological treatments. To assess together safety, tolerance and efficacy of Carmustine wafer implantation and of extent of resection for glioblastoma patients in real-life experience. Observational retrospective monocentric study including 340 consecutive adult patients with a newly diagnosed supratentorial glioblastoma who underwent surgical resection with (n = 123) or without (n = 217) Carmustine wafer implantation as first-line oncological treatment. Carmustine wafer implantation and extent of resection did not significantly increase postoperative complications, including postoperative infections (p = 0.269, and p = 0.446, respectively). Carmustine wafer implantation and extent of resection did not significantly increase adverse events during adjuvant oncological therapies (p = 0.968, and p = 0.571, respectively). Carmustine wafer implantation did not significantly alter the early postoperative Karnofsky performance status (p = 0.402) or the Karnofsky performance status after oncological treatment (p = 0.636) but a subtotal or total surgical resection significantly improved those scores (p < 0.001, and p < 0.001, respectively). Carmustine wafer implantation, subtotal and total resection, and standard combined chemoradiotherapy were independently associated with longer event-free survival (adjusted Hazard Ratio (aHR), 0.74 [95% CI 0.55–0.99], p = 0.043; aHR, 0.70 [95% CI 0.54–0.91], p = 0.009; aHR, 0.40 [95% CI 0.29–0.55], p < 0.001, respectively) and with longer overall survival (aHR, 0.69 [95% CI 0.49–0.96], p = 0.029; aHR, 0.52 [95% CI 0.38–0.70], p < 0.001; aHR, 0.58 [95% CI 0.42–0.81], p = 0.002, respectively). Carmustine wafer implantation in combination with maximal resection, followed by standard combined chemoradiotherapy is safe, efficient, and well-tolerated in newly diagnosed supratentorial glioblastomas in adults.

Acrodysostosis and Spinal Canal Involvement

Georges Abi Lahoud; Nohra Chalouhi; Pascal Jabbour

BACKGROUND Acrodysostosis is a rare syndrome characterized by peripheral dysostosis, nasal hypoplasia, and frequently mental retardation. Only two adult cases of acrodysostosis have been reported to have neurological symptoms. CASE DESCRIPTION We report one additional adult case that presented with signs of spinal cord compression from spinal stenosis, and make the first histologic description in the literature of the bony anomalies seen in acrodysostosis. The patient had a T3 to T5 laminectomy and experienced a complete recovery. CONCLUSIONS Special attention should be given to these patients to detect signs of spinal stenosis, as early decompression can lead to neurological recovery.

Spontaneous Regression of a Third Ventricle Colloid Cyst

Sophie Peeters; Badih Daou; Pascal Jabbour; Alexandre Ladoux; Georges Abi Lahoud

BACKGROUND Colloid cysts represent 0.5%-1% of intracranial tumors and most commonly occur in the third ventricle near the Monro foramen. Although benign, if the lesion obstructs the foramen abruptly, sudden death may ensue. Evolution of these cysts is poorly understood. Spontaneous regression has been reported in only 2 other cases. Management of such cysts depends on whether the cyst continues to grow, its location, and clinical presentation. Incidental asymptomatic colloid cysts are typically followed with neuroimaging surveillance. CASE DESCRIPTION We present a case of an incidental third ventricle colloid cyst in a 46-year-old patient who was managed conservatively with neuroimaging surveillance. Thereafter, she started developing some working memory deficits and intermittent headaches, with the cyst volume increasing, leading to the decision to perform a resection. However, the cyst underwent spontaneous regression before the scheduled surgery date, 3 years after initial diagnosis. CONCLUSIONS This case confirms that some colloid cysts could regress spontaneously. Disappearance of the cyst is not necessarily accompanied by clinical worsening, as was reported by other investigators who noted deteriorating neurologic deficits as a result of worsening hydrocephalus. Assuming the cysts rupture, some patients tolerate the contents of the cyst leaking into the ventricular system, whereas others may mount an inflammatory reaction, causing a disruption in cerebrospinal fluid flow. In addition, it is still unclear what factors increase the likelihood of cysts to suddenly rupture.

Multimodal optical imaging database from tumour brain human tissue: endogenous fluorescence from glioma, metastasis and control tissues

Eliminating time-consuming process of conventional biopsy is a practical improvement, as well as increasing the accuracy of tissue diagnoses and patient comfort. We addressed these needs by developing a multimodal nonlinear endomicroscope that allows real-time optical biopsies during surgical procedure. It will provide immediate information for diagnostic use without removal of tissue and will assist the choice of the optimal surgical strategy. This instrument will combine several means of contrast: non-linear fluorescence, second harmonic generation signal, reflectance, fluorescence lifetime and spectral analysis. Multimodality is crucial for reliable and comprehensive analysis of tissue. Parallel to the instrumental development, we currently improve our understanding of the endogeneous fluorescence signal with the different modalities that will be implemented in the stated. This endeavor will allow to create a database on the optical signature of the diseased and control brain tissues. This proceeding will present the preliminary results of this database on three types of tissues: cortex, metastasis and glioblastoma.

Association of Lhermitte-Duclos disease and split cord malformation in a child.

Georges Abi Lahoud; Nohra Chalouhi; Mario Zanaty; Tony Rizk; Pascal Jabbour

Lhermitte-Duclos disease (LDD) or cerebellar gangliocytoma is a rare pathological entity, the etiology of which remains controversial. Numerous developmental anomalies are known to be associated with LDD, but the association between LDD and split cord malformation (SCM) has not been reported to our knowledge. We report LDD in a 3-year-old girl in whom repetitive urinary tract infections led to the diagnosis of a neurogenic bladder. Thorough screening revealed a SCM at the thoracic level which was surgically repaired. The pathogenesis of this entity and management strategies are discussed in this paper.
