Skull Vault Plasmacytoma Mimicking Parasagittal Meningioma: "Mini-Brain Appearance".

Plasmacytomas occur as lesions in soft tissue or bone. Skull vault plasmacytomas are rare lesions comprising 0.7% of all plasmacytomas. Workup for myeloma must be done in such cases to rule out multiple myeloma. Here, we report a case of a 63-year-old female who presented to us with a large skull vault swelling which appeared to mimic a parasagittal meningioma on imaging. Histopathological imaging revealed it to be a plasmacytoma. A retrospective review of the radiology revealed the characteristic "mini-brain appearance" in our case. Literature on the subject is also reviewed.

Glioma Simultaneously Present with Adjacent Meningioma: Case Report and Literature Review.

A 51-year-old male patient presented to us with an episode of generalized tonic-clonic seizure. Magnetic resonance imaging revealed a dural-based contrast-enhancing lesion in the right temporal lobe and another heterogeneously contrast-enhancing intra-axial lesion in the right insula adjacent to it. Histopathology confirmed it as a meningioma adjacent to an anaplastic oligodendroglioma. This is only the second such case reported in literature. Literature on "adjacent site" gliomas and meningioma was also reviewed.

Giant Bilateral Calvarial Hyperostosis Secondary to Small Unilateral Frontal Meningioma.

A 28-year-old male patient presented to us with bilateral frontal hyperostosis associated with a small unilateral frontal intracranial meningioma. He underwent successful excision of the involved bone and repair of the large cranial defect using a titanium mesh. Histological examination revealed tumor infiltration of the overlying bone. Surgical challenges in the management of such a case are also discussed.

Basal Ganglia Infarct following Trivial Trauma in a Child: Case Report and Review of Literature.

A 2-year-old boy was presented to us with right-side hemiparesis after trivial fall. Diffusion-weighted magnetic resonance imaging showed an infarct in left basal ganglia and thalamic region. Secondary causes of stroke were ruled out. The child was managed conservatively. Basal ganglia infarct secondary to minor trauma is a rare event. Possible mechanisms leading to such an event and its management are discussed.

Subaponeurotic Cerebrospinal Fluid Collection in an Infant.

Subaponeurotic cerebrospinal fluid (CSF) collection is a rare condition. We report a 13-week-old male infant who presented with a swelling in the occipitoparietal region of 4 h duration. Swelling was soft, fluctuant, and contained CSF. It was tapped twice on the 4th and 8th day of appearance and resolved completely by 7 weeks. The condition is benign, and a conservative approach is recommended.

Acute unilateral post-operative submandibular sialadenitis following posterior cranial fossa surgery.

Extreme degree of rotation and flexion of the head during posterior fossa surgeries can lead to acute post-operative submandibular sialadenitis that can cause respiratory compromise. Identification of this problem is vital to prevent deterioration in the early post-operative period. This condition responds well to conservative management provided airway obstruction is taken care of. We discuss a case of a 63-year-old female, with a left side vestibular schwannoma who developed airway obstruction in post-operative period due to swelling of right submandibular gland. Various possible mechanisms leading to this condition and related literature are briefy reviewed.

Internal decompression for spinal stenosis (IDSS) for decompression and use of interlaminar dynamic device (CoflexTM) for stabilization in the surgical management of degenerative lumbar canal stenosis with or without mild segmental instability: our initial results.

INTRODUCTION: Internal decompression of spinal stenosis (IDSS) and Posterior dynamic stabilization (PDS) form a bridge between decompression laminectomy alone and rigid fusion, by attempting to sustain beneficial effects of decompression and stabilization in an attempt to prevent bad effects of relentless degeneration. OBJECTIVE: To evaluate the clinical outcome in operated patient of posterior dynamic stabilization. DESIGN: Data were collected over 1 year in prospective, nonrandomized follow-up study using outcome scales. SETTING: Single surgeon, tertiary care centre in Mumbai, India. Described here is the operative technique of posterior dynamic stabilization using CoFlexTM and clinical outcome of 67 consecutive patients using Visual Analogue Scale and Oswestry Disability Score.

Primary dorsal spine primitive neuroectodermal tumor in an adult patient: Case report and literature review.

Primary spinal primitive neuroectodermal tumor (psPNET) is a rare entity with few cases reported in literature. We report a case of a 50-year-old female who presented to us with paraplegia and was diagnosed with extradural dorsal spine psPNET. The diagnosis was not suspected at presentation or on radiology but was established on histopathological examination. It is important to distinguish it from central nervous system primitive neuroectodermal tumors and from other spinal tumors since it follows a different clinical course and therapeutic outcome.

Giant pediatric intraventricular meningioma: Case report and review of literature.

Intraventricular meningiomas are rare in the pediatric population. These tumors are often large in size and aggressive in behavior when they occur in children. The management of these tumors is a surgical challenge.

Infant brain tumours: a tale of two cities.

INTRODUCTION: Infantile brain tumours (age < 1 year) are increasingly being diagnosed due to advances in prenatal and perinatal diagnostic imaging. We present here our retrospective study of 64 infant brain tumours that brings to the fore the epidemiology, clinical presentation, pathology and outcome of this unique subset of paediatric brain tumours presenting to two tertiary referral centres in Kolkata in India and Lille in France between the years 1999 and 2014. METHODS: Data was retrospectively collected from Kolkata (n = 30) and Lille (n = 34) for patients presenting with infant brain tumours and analysed for factors such as age at presentation, clinical features, gender, location of tumour, pathology, management and outcome. Follow-up was available for all patients. RESULTS: Mean age at presentation was 6.8 months at Kolkata and 6.3 months at Lille. More than two-thirds of tumours in both the groups were supratentorial and presented with signs of raised intracranial pressure. There was also a similar proportion of tumours presenting as congenital tumours. At Kolkata, germ cell tumours (n = 7) were the most common while low-grade gliomas (n = 11) formed the largest group at Lille. Kolkata had a higher incidence of high-grade gliomas (n = 5) and PNETs (n = 4) while ATRT (n = 3) and choroid plexus carcinoma (n = 4) were more common at Lille. Surgery was the mainstay of treatment at both centres. CONCLUSION: Brain tumours in infants presenting to tertiary centres in Europe and India are challenging to manage and usually have dismal prognosis. These tumours differ markedly in the pathology and, therefore, overall outcome. Surgery forms mainstay of treatment. Radiotherapy is best avoided in this age group.
