Primary melanocytic tumours of the central nervous system (CNS) are rare. According to the WHO classification (2007), these tumours include diffuse leptomeningeal melanosis, melanomatosis, melanocytoma, and primary CNS melanoma. Meningeal melanocytoma, most commonly seen in the infratentorial compartment and cervical spinal cord, is a benign primary melanocytic neoplasm. Primary CNS melanoma, on the other hand, represents the malignant end of the spectrum. Intermediate grade melanocytoma is a rare histological subtype of primary meningeal tumours and is characterised by the clinicopathological features between the two extremes...

Schwannomatosis is a disease characterized by the development of multiple benign tumours originating from Schwann cells. Schwannomatosis is a member of the family of diseases known as Neurofibromatosis (NF). Patients with Schwannomatosis develop multiple Schwannomas on cranial, spinal and peripheral nerves. We report a rare case of a 60-year-old female who presented with a painful swelling on the ulnar aspect of her distal forearm. She underwent an excisional biopsy for it; which was suggestive of a Schwannoma...

Neurogenic tumours of the paraspinal space can occur in all age groups. It is common in adult population and relatively rare in elderly group. Usually they are benign, but in children, arising from the autonomic system, tends to be malignant in nature. Usually in adults, they arise from peripheral nerve sheath and are labelled as schwannomas. For a given tumour, determination of a correct surgical approach is mandatory to achieve a successful surgical outcome. Several factors like tumour size, histology, involvement of the bony spinal canal, etc...

Head and neck cancer (HNC) is a challenging tumour site for radiotherapy delivery owing to its complex anatomy and proximity to organs at risk (OARs) such as the spinal cord and optic apparatus. Despite significant advances in radiotherapy planning techniques, radiation-induced morbidities remain substantial. Further improvement would require high-quality imaging and tailored radiotherapy based on intratreatment response. For these reasons, the use of MRI in radiotherapy planning for HNC is rapidly gaining popularity...

Chordoma is a rare, slow-growing tumour arising from remnants of the notochord. It is most often located in the base of the skull and the sacrococcygeal region, being located in the cervical region in only 6% of cases. A rare case is presented of a left para-spinal chordoma, of which less than 10 cases have been reported in literature. It was located at C2-C4 level in a young male with no personal history of interest. Radiographic findings suggested that this was a slow-growing tumour, of cystic dominance, which eroded the bone structures and encompassed the left vertebral artery...

Neurofibromatosis type 1 is a complex autosomal dominant disorder caused by germline mutations in the NF1 tumour suppressor gene. Nearly all individuals with neurofibromatosis type 1 develop pigmentary lesions (café-au-lait macules, skinfold freckling and Lisch nodules) and dermal neurofibromas. Some individuals develop skeletal abnormalities (scoliosis, tibial pseudarthrosis and orbital dysplasia), brain tumours (optic pathway gliomas and glioblastoma), peripheral nerve tumours (spinal neurofibromas, plexiform neurofibromas and malignant peripheral nerve sheath tumours), learning disabilities, attention deficits, and social and behavioural problems, which can negatively affect quality of life...

Rhabdoid phenotype and biallelic mutations of the SMARCB1 gene causing loss of SMARCB1/INI1 protein expression are the hallmark of atypical teratoid/rhabdoid tumour (AT/RT), a highly malignant central nervous system tumour mainly affecting infants [1]. Loss of SMARCB1/INI1 protein expression has also been described in a variety of other rhabdoid and non-rhabdoid tumour entities including cribriform neuroepithelial tumour (CRINET) [2], poorly differentiated chordoma [3] as well as rhabdoid peripheral nerve sheath tumour [4] and familial schwannomatosis [5]...

The most frequent recurring mutations in neurofibromatosis type 1 (NF1) are large deletions encompassing the NF1 gene and its flanking regions (NF1 microdeletions). The majority of these deletions encompass 1.4-Mb and are associated with the loss of 14 protein-coding genes and four microRNA genes. Patients with germline type-1 NF1 microdeletions frequently exhibit dysmorphic facial features, overgrowth/tall-for-age stature, significant delay in cognitive development, large hands and feet, hyperflexibility of joints and muscular hypotonia...

A male patient presented at the age of 30 with classic clinical features of acromegaly and was found to have elevated growth hormone levels, not suppressing during an oral glucose tolerance test. His acromegaly was originally considered to be of pituitary origin, based on a CT scan, which was interpreted as showing a pituitary macroadenoma. Despite two trans-sphenoidal surgeries, cranial radiotherapy and periods of treatment with bromocriptine and octreotide, his acromegaly remained active clinically and biochemically...

Chordoma is a rare, indolent but locally invasive, osteolytic, slow growing, low grade, primary bone malignancy, derived from the embryonic remnants of the notochord. It is a midline tumour and it predominantly emerges from the axial skeleton. The most commonly observed location of a chordoma is in the sacrococcygeal region ( 50 to 55% ) followed by the cranio occipital region ( 25 to 30% )We present a case of a 30 years old lady who came to us with complaints of difficulty in walking and inability to hold objects in both hands...

This report describes the history, clinical examination and histopathology of a histiocytic sarcoma in a domestic ferret. Clinical signs were acute paraplegia and dysuria. Physical examination revealed a firm, smooth, touch-sensitive mass in and around the lumbar vertebral column. Neurologic examination was consistent with a lesion between spinal cord segments T3 and L3. Magnetic resonance images revealed bone lesions of L2 and L3 combined with compression of the spinal cord due to a homogenous, isointense mass that was diagnosed as a malignant round cell tumour and the ferret was euthanased...
