BACKGROUND: The Cerebellar Mutism Syndrome (CMS) is rarely described in adults; however data on self-assessed linguistic complications after posterior fossa surgery do not exist. METHODS: Through a prospective single-centre study data on 59 tumour operations in the posterior fossa data was collected preoperatively as well as 1 week and 1 month postoperatively. Data on self-assessed problems in five CMS-related domains, CMS-scores, neurology as well as surgical procedure and complications were obtained...

Endolymphatic sac tumour (ELST) is infrequent, as emerges from small series reported in the literature. It is a slow-growing malignancy with local aggressiveness and a low risk of distant metastases. It is often misdiagnosed because of the late onset of symptoms and difficulty in obtaining a biopsy. Its frequency is higher in von Hippel-Lindau (VHL) disease (a genetic systemic syndrome involving multiple tumours), with a prevalence of around 25%. The diagnosis is based on radiology, with specific patterns on contrast-enhanced MRI and typical petrous bone erosion on bone CT scan...

Although atypical meningioma recurs frequently in spite of total resection and/or radiotherapy, no consensus on optimal adjuvant management was found. However, several retrospective studies analysed the additional effect of adjuvant radiotherapy in atypical meningioma with inconsistent results. Therefrom, the purpose of this study was to evaluate prognostic factors influencing the recurrence/progression and progression-free survival (PFS) rates of atypical meningioma, particularly focused on the role of postoperative adjuvant radiotherapy...

PURPOSE: To evaluate neuroendocrine late effects in paediatric patients with low grade glioma (LGG) who underwent radiotherapy. METHODS AND MATERIAL: We performed a retrospective evaluation of 40 children with LGG treated from July 2002 to January 2015 with external radiotherapy. Tumour locations were cerebral hemisphere (n=2); posterior fossa (n=15); hypothalamic-pituitary axis (HPA, n=15); spine (n=5). Three patients presented a diffuse disease. We looked for a correlation between endocrine toxicity and tumour and treatment parameters...

Background: Brain tumours are the most common solid tumours in children. More than 50% of these tumours develop in the posterior cranial fossa. Long term survivors of posterior fossa tumours (PFT) suffer from neurocognitive and memory issues. We hypothesized that serial MRI scanning of brain would show differences in hippocampal and ACC volume change in PFT patients treated with and without chemo-radiotherapy. Material and Methods: Twelve patients (8 females and 4 males) underwent 76 serial MR imaging examinations before and during treatment for posterior fossa tumours...

The purpose of this paper is to serve as a reference to aid in the management of this poorly understood intracranial malignancy. The authors report their experience treating the eighth ostensible case of a primary intracranial alveolar soft part sarcoma (ASPS). A 21-year-old man presented to hospital after collapsing. He gave a 1-year history of headache, a 2-month history of reduced visual acuity and on examination had left facial paraesthesia with left-sided incoordination. MRI of the brain revealed a large left posterior fossa mass...

INTRODUCTION: Medulloblastoma is the most frequent malignant brain tumour in children. Radiation-induced cavernous haemangiomas (RICHs) are a known late complication of radiation exposure, especially in young children. CASE REPORT: We present a patient who underwent subtotal resection of posterior fossa medulloblastoma with subsequent chemotherapy and radiotherapy at the age of 10 years. A new lesion in the region of the left foramen of Monro appeared 16 years later...

BACKGROUND: Central nervous system tumours constitute 25% of all childhood cancers; more than half are located in the posterior fossa and surgery is usually part of therapy. One of the most disabling late effects of posterior fossa tumour surgery is the cerebellar mutism syndrome (CMS) which has been reported in up to 39% of the patients but the exact incidence is uncertain since milder cases may be unrecognized. Recovery is usually incomplete. Reported risk factors are tumour type, midline location and brainstem involvement, but the exact aetiology, surgical and other risk factors, the clinical course and strategies for prevention and treatment are yet to be determined...

To analyze treatment interruptions due to acute hematological toxicity in patients of medulloblastoma receiving cranio-spinal irradiation (CSI). Prospectively collected data from case records of 52 patients of medulloblastoma treated between 2011 and 2014 was evaluated. Blood counts were monitored twice a week during CSI. Spinal irradiation was interrupted for patients with ≥grade 2 hematological toxicity and resumed after recovery to grade 1 level (TLC >3000; platelet count >75,000). Treatment interruptions and hematological toxicity were analyzed...

Juvenile nasopharyngeal angiofibroma is tumour almost exclusively seen in adolescent males, constituting less than 1% of all neoplasms in head and neck. They are benign and locally spreading and are highly vascular in nature and thus prove to be a surgical challenge because of its complex anatomical location. Here, we present a case report of a 18-year-old male presenting with a mass in his left nasal cavity, with recurrent epistaxis and nasal obstruction. Computed tomography imaging revealed a non-encapsulated lobulated heterogeneous mass lesion in the naso-pharynx and left posterior choana of the nasal cavity, extending to pterygopalatine and infratemporal fossa, masseter space of left side...

We present a female infant with a right-sided facial and neck haemangioma, from a remote, resource-poor community in rural Guatemala. She received first-line treatment, propranolol, with marked reduction in tumour size and erythema. Treatment was stopped after 35 weeks due to recurrent diarrhoea and sustained weight loss. Propranolol can be used to safely treat infants with haemangiomas in remote, rural communities if there is adequate follow-up, education and communication. Periocular haemangiomas should be treated promptly to avoid visual impairment...

Von Hippel-Lindau (VHL) disease is a rare autosomal dominantly inherited multisystem disorder characterised by the development of a variety of benign and malignant tumours. We report a case of VHL disease that was inherited by a daughter from her father, who both presented at a young age with progressive headache and were found to have a posterior fossa haemangioblastoma (HB) on magnetic resonance imaging (MRI). Multiple benign pancreatic and renal cysts were also noted in both patients.

BACKGROUND: For tumours near organs at risk, there is concern about unintended increase in biological dose from elevated linear energy transfer (LET) at the distal end of treatment fields. The objective of this study was therefore to investigate how different paediatric posterior fossa tumour locations impact LET and biological dose to the brainstem during intensity-modulated proton therapy (IMPT). MATERIAL AND METHODS: Multiple IMPT plans were generated for four different simulated tumour locations relative to the brainstem for a five-year-old male patient...

AIMS: Craniospinal irradiation (CSI) remains a crucial treatment for patients with medulloblastoma. There is uncertainty about how to manage meningeal surfaces and cerebrospinal fluid (CSF) that follows cranial nerves exiting skull base foramina. The purpose of this study was to assess plan quality and dose coverage of posterior cranial fossa foramina with both photon and proton therapy. MATERIALS AND METHODS: We analysed the radiotherapy plans of seven patients treated with CSI for medulloblastoma and primitive neuro-ectodermal tumours and three with ependymoma (total n = 10)...

A 36-year-old woman, with history of cutaneous papilomatosis and thyroid carcinoma presented with headache, transitory visual blurring and nausea. Funduscopy showed papilloedema. MRI showed a tumour of the right cerebellar hemisphere with a striated, tigroid pattern, typical of Lhermitte-Duclos disease (LDD). Significant clinical and perimetric improvements were noted after surgery and the follow-up did not reveal recurrences of the tumour. LDD is an extremely rare differential diagnosis of posterior fossa tumours...

We report the case of a supra and infratentorial ectopic schwannoma, mimicking a meningioma, that was surgically resected on a 75-year-old man, with a history of progressive visual loss and headaches. MRI was in favour of an occipital, cystic, tentorial-based meningioma extending to the posterior fossa, with signs of intratumoral haemorrhage. This is a unique case because of the rare type of lesion, in a very atypical location, completely unexpected by the preoperative imaging analysis, and to the best of our knowledge it is the oldest patient reported in the literature with this kind of tumour...

Posterior fossa syndrome (PFS), or cerebellar mutism syndrome (CMS), is a collection of neurological symptoms that occur following surgical resection of a posterior fossa tumour, and is characterised by either a reduction or an absence of speech. Some authors suggest that CM is only one symptom of the CMS complex that also includes ataxia, hypotonia and irritability as well as cranial nerve deficits, neurobehavioral changes and urinary retention or incontinence. It is seen almost exclusively in children. In 1985 Rekate et al...

BACKGROUND: The dentato-thalamo-cortical (DTC) pathway is recognized as the anatomical substrate for postoperative pediatric cerebellar mutism (POPCMS), a well-recognized complication affecting up to 31% of children undergoing posterior fossa brain tumour resection. The proximal structures of the DTC pathway also form a segment of the Guillain and Mollaret triangle, a neural network which when disrupted causes hypertrophic olivary degeneration (HOD) of the inferior olivary nucleus (ION)...

Ependymomas are the third commonest paediatric central nervous system (CNS) tumour, accounting for 6-12% of brain tumours in children. The management of these tumours has seen considerable changes over the last two decades, leading to a significant improvement in outcomes. However, despite advances in neurosurgical, neuroimaging and postoperative adjuvant therapy, management of these tumours remain challenging, and recurrence occurs in over 50% of cases, particularly when complete resection is not achieved prior to conformal radiotherapy...
