 Background: Decompressive Craniectomy is a surgical procedure in neurosurgery to handle brain swelling subsequent to trauma, vascular insult, or tumor. There are different techniques and measurements of decompressive craniectomy performed worldwide. We follow the regular trauma flap involving fronto-temporo-parietal craniectomy. There have been many complications seen in these procedures, like brain herniation, malignant swelling, hydrocephalus, infection, etc. But we have encountered quite rare complications of decompressive craniectomy which had massive swelling of the temporalis muscle leading to significant mass effect and midline shift.

Abstract Movement disorders are atypical and rare presentation of chronic subdural hematomas. We report a case of 60 year man who presented with intention tremors and altered sensorium. The patient had Kernohan-Woltman notch phenomenon on clinical examination. CT scan brain showed a large left fronto-temporo-parietal chronic subdural hematoma with significant mass effect and midline shift. His symptoms relieved completely after surgical evacuation of the hematoma.

Abstract Pneumocephalus can develop immediately following head trauma or clinical presentation may be delayed for days. We report a case of 35 year male whose initial CT scan brain plain small specks of pneumocephalus in left para-sellar region. However the next day he was complaining of severe headache and had multiple episodes of vomiting. Repeat CT scan showed increase in the size of pneumocephalus including appearance of intraventricular air with mild cerebral edema. The patient recovered well with conservative management. The present case is a gentle reminder that in a subgroup of head injury patients, intracranial air can produce significant mass effect leading to tension pneumocephalus which can can behave like other intracranial mass lesions and causes worsening of the neurological status of these patients.

Quasiclassical Trajectory (QCT) calculation for O(3P) + HD → OH + D and O(3P) + HD → OD + H at E col = 0.4–1.0 eV and 0.5–1.0 eV, respectively, on the lowest PES 1 3A″ of Kuppermann et al. has been done. Distribution p(ϑr) of azimuthal angles between the relative velocity k of the reactants and rotational angular momentum vector j′ of either OH or OD , p(φr) of polar as well as dihedral angles correlating k - k′ -j′, p(ϑr, φr), and PDDCS dependent upon the scattering angle ϑt of either OH , or OD between k and k′ of the reactants and products, respectively, are presented and discussed. The stereodynamics and isotopic mass effects at the smallest possible collision energies 0.4 eV and 0.5 eV for OH and OD , respectively, are significantly different. The significant mass effect with quotient 1/2 of H/D, at the corresponding collision threshold may be applied for the investigation of docking mechanism, drug modification and delivery.

Spontaneous thrombosis in giant aneurysms is known, whereas complete occlusion of such aneurysms in a short period of time is rarely reported. We present the case of a 50-year-old man with a giant anuersym arising from the anterior communicating artery (ACA) producing significant mass effect with clinical consequences. The digital subtraction arteriogram (DSA) showed a patent lumen of about 20 mm and a very small neck leading to extremely slow blood flow inside the sac and stagnation of contrast. During catheterization for endovascular occlusion four weeks later, the arteriogram revealed complete disappearance of the aneurysm, while the patient remained clinically stable. The patient was operated upon and the thrombosed sac was removed with no complications. He was discharged one week later and recovered completely from his symptoms within three months.

Case Presentation: A 63-year-old female presented to the emergency department complaining of cough, neck swelling, dysphagia, and dysphonia for two days, with a past medical history of atrial fibrillation managed with warfarin. Investigations revealed a supratherapeutic international normalised ratio (greater than 10). Imaging and endoscopic examination showed an extensive retropharyngeal hematoma with significant mass effect on the airway. Discussion: A rare but potentially fatal complication of warfarin anticoagulation is upper airway hematoma, with violent coughing described as an inciting cause. Signs of airway compromise necessitate specialist consultation and definitive airway management, while mild cases without airway concerns can be managed conservatively with medical anticoagulation reversal.

Decompressive craniectomy, which is performed worldwide for the treatment of severe traumatic brain injury (TBI), is a surgical procedure in which part of the skull is removed to allow the brain to swell without being squeezed. On 1901, Kocher was the first surgeon to promote surgical decompression in posttraumatic brain swelling. In this article, different methods of decompressive craniectomy and its technical considerations have been reviewed.

Epidural hematomas (EDHs) are sometimes treated nonoperatively. Decision making, however, is not always perfect, and some hematomas chosen for observation later deteriorate and require surgical clot removal. With the current endovascular technology it is possible to embolize meningeal arteries to stop epidural bleeding. In this study, the author presents his experience in the treatment of a patient with a troublesome postoperative EDH successfully controlled with embolization therapy. This treatment is also useful in posttraumatic EDH and may obviate the need for surgery in some patients with EDHs who present early after injury and without significant mass effect.

Background: Giant cavernous malformations of the central nervous system are quite rare. They are more common in children and may be misdiagnosed as other intracranial neoplasms. Here, we presented a very rare giant cavernous angioma mimicking a neoplastic temporal lobe lesion in an 18-month-old male. Case Description: An 18-month-old male presented with two initial seizures. Although the clinical examination was normal, the computed tomography (CT) scan showed a large left temporal mass (66 mm diameter) exerting significant mass effect and midline shift. The brain magnetic resonance (MR) imaging demonstrated a large left temporal heterogeneously enhancing lesion with significant perilesional edema and mass effect. The patient underwent gross total removal of the lesion that proved to be an intracranial cavernous angioma. Postoperatively, he did well, exhibiting no residual neurological deficit, and has remained lesion and seizure-free. Conclusion: This and 12 other cases in the literature focus on intracranial cavernous angiomas that could have been readily misdiagnosed as tumors. It confirms why obtaining appropriate preoperative MR and CT studies, followed by surgical intervention, is essential to confirm the correct underlying pathology and appropriately and optimally treat the patient.
