Cirsoid Aneurysm of the Scalp: A case report

Cirsoid aneurysms (arteriovenous malformations [AVMs]) are Anomalous fistulous arteriovenous communications of scalp with ill-defined natural course that are rarely encountered in neurosurgery. Patients with AVM of the scalp present clinically with headache and either a small innocuous-looking subcutaneous scalp lump or a large, pulsatile mass with or without bruit, which has a propensity to massive hemorrhage. Complex vascular anatomy and interconnections and high shunt flow make their management difficult. We report a rare case of a 40-year-old man who presented with a swelling over his occipital region that progressively enlarged over the course of 6 years. Being high flow shunt surgical excision was attempted

Burr hole site acute extradural hematoma after ventriculoperitoneal shunt surgery: A rare case report and its pathogenesis

Ventriculoperitoneal (VP) shunt, a common neurosurgical procedure, has a long list of known complications associated with it. A rare but dangerous complication of VP shunt procedure is extradural hematoma (EDH). It can be diagnosed and managed easily before it turns into a catastrophic complication

Primary sinonasal undifferentiated carcinoma with intracranial extension presenting postoperatively as garcin syndrome: A rare case report and review of literature

Sinonasal undifferentiated carcinoma (SNUC) is an aggressive malignancy originating in the mucosa lining the walls of the nasal cavity and paranasal sinuses. It is a rare tumor that usually presents in an advanced stage, is highly invasive, and is traditionally reputed to be refractory to even the most radical therapy with an attendant poor prognosis. This is particularly true when it transgresses the cranial base

Dorsolumbar angiolipoma: A rare case report and review of literature

A 55-year-old female was presented with complaints of tingling sensations of the bilateral lower limb with spastic paraplegia for last one year. Her pre-operative contrast MRI study of Dorsolumbar Spine was suggestive of extradural angiolipoma. She underwent D11, D12 and L1 Laminectomy and a mildly vascular yellowish globular extradural mass was found which was excised completely and dural decompression was achieved. Post-operatively, the patient’s neurologic symptoms improved. Conclusion: Spinal angiolipoma is considered a rare benign entity which emulates malignancy. It should be included as a differential diagnosis of the spinal epidural tumour with fat component and a high degree of vascularisation. surgical removal of this epidural tumour through a proper and comprehensive approach provides complete and permanent recovery

Time-dependent in situ measurement of atmospheric corrosion rates of duplex stainless steel wires

Stainless steel: Comprehending corrosion The corrosion of two grades of stainless steel has been studied, in situ, under atmospheric exposure conditions. Grade ‘2205’ duplex stainless steel (DSS) has been suggested as a possible container material for the storage of intermediate-level radioactive nuclear waste in the UK because of its high resistance to corrosion and stress corrosion cracking (SCC). Now a team led by D. Engelberg from The University of Manchester, United Kingdom, have used time-lapse X-ray computed tomography to determine the corrosion rates of strained grade ‘2202’ and ‘2205’ DSS wires—over the course of 21 months—that had been exposed to a chloride-containing thin-film electrolyte. They saw that although the corrosion rate of grade 2202 DSS wires increased with time, the corrosion rate for grade 2205 decreased, confirming its superior corrosion resistance. They also observed the nucleation of SCC cracks in both grades of wire and demonstrated that duplex stainless steels can suffer from low-temperature SCC
