Traumatic dural sinus thrombosis causing persistent headache in a child

Dural venous sinus thrombosis following a mild head injury is increasingly recognized. We report case of a 9-year-old male child presented with progressive headache and vomiting following a minor fall. A diagnosis of sinus venous thrombosis was suspected on nonenhancing computed tomography, and that was confirmed with magnetic resonance venography. The child was managed with intravenous fluids, anticoagulation (injection heparin followed by oral anticoagulants–tab coumarin), antiedema measures (mannitol), and antiepileptics (phenytoin) with good outcome.

Malignant hemangioendothelioma of occipital bone

Epithelioid hemangioendothelioma is a rare vascular tumor of bone, and rarely these lesions can present as unique and extremely aggressive tumor. We report a case of highly aggressive epithelioid hemangioendothelioma and discuss the imaging findings. CT brain plain study revealed a poorly-defined, mixed density expansile and lytic lesion involving the occipital bone with extension to the left side with poorly defined trabecula formation. There was significant but irregular enhancement after intravenous administration of contrast material and also marked bone destruction. Microscopic examination of the fine needle aspiration cytology showed a tumor composed of vascular channels lined by plump endothelial cells, which had enlarged hyperchromatic nuclei. In view of the extensive infiltration the patient was submitted for the radiotherapy.

Mount Fuji sign with concavo-convex appearance of epidural haematoma in a patient with tension pneumocephalus

Intracranial pneumatocele is a non-infected accumulation of air within the cranial cavity. We report a case of a 22-year-old male who sustained a fracture of anterior cranial fossa following a motor vehicle accident and the imaging findings showed a concave-convex epidural haematoma. Simple traumatic pneumocephalus usually does not require surgical treatment and non-operative management has been advocated for small, asymptomatic convexity extradural haematomas.

Histological changes in kidneys of adult rats treated with Monosodium glutamate: A light microscopic study

Introduction: Monosodium Glutamate (MSG), which is chemically known as AJI-NO-MOTO also familiar as MSG in routine life. MSG is always considered to be a controversial food additive used in the world. It is a natural excitatory neurotransmitter, helps in transmitting the fast synaptic signals in one third of CNS. Liver and kidney play a crucial role in metabolism as well as elimination of MSG from the body. Present study is to detect structural changes in adult rat kidney tissue treated with MSG; observations are done with a light microscope. Materials & Methods: The study was conducted in the department of Anatomy, J.N.M.C, Sawangi (M) Wardha. Thirty (30) adult Wistar rats (2-3 months old) weighing about (200 ± 20g) were used in the current study, animals were divided into three groups (Group – A, B, C). Group A: Control, Group B: 3 mg /gm body weight, Group C: 6 mg /gm body weight, MSG were administered orally daily for 45 days along with the regular diet. Observations & Results: The Mean values of animals weight at the end of experiment (46th day) respectively were 251.2 ± 13, 244.4 ± 19.9 and 320 ± 31.1. Early degenerative changes like, Glomerular shrinkage (GSr), loss of brush border in proximal convoluted tubules and Cloudy degeneration was observed in sections of kidney treated with 3 mg/gm body weight of MSG. Animals treated with 6 mg/gm body weight of MSG showed rare changes like interstitial chronic inflammatory infiltrate with vacuolation in some of the glomeruli, and much glomerular shrinkage invaginated by fatty lobules. Conclusion: The effects of MSG on kidney tissues of adult rats revealed that the revelatory changes are directly proportional to the doses of MSG.

Simultaneous hemorrhage in intracranial aneurysms and in renal cyst in a case of polycystic kidney disease

We report an unusual case of simultaneous hemorrhage in intracranial aneurysms and in renal cyst in a case of polycystic kidney disease. A 27-year-old gentleman presented with progressive headache and intermittent vomiting of one month duration. Initial computerized tomography (CT) scan and magnetic resonance imaging/angiography revealed a large mass lesion in the right temporal fossa. Over the previous 15 days, he developed progressive weakness in his left upper and lower limbs, and the headache worsened in severity. A repeat of CT scan showed an evidence of aneurysmal bleed and a large temporal lobe hematoma. The patient underwent urgent evacuation of the intracerebral of hematoma and excision of the redundant aneurysmal sac. The patient made excellent recovery in the post-operative period; however, for him, the pain abdomen was persisting. Detailed work-up with contrast-enhanced abdominal CT scan revealed bilateral multiple cysts in the kidneys with evidence of intracystic hemorrhage on the left side. An extensive search of the literature revealed that this kind of presentation has not been reported previously.

Acute onset progressive hemiparesis in a case of head and neck injury

Traumatic carotid artery injury is an increasingly recognized complication of severe blunt head or neck trauma in patients with motor vehicle accidents. A 22-year-old male presented after a high-velocity road traffic accident and sustained head, neck and systemic injuries. Initially the patient was neurologically stable and initial CT scan brain was also apparently normal. Few hours after the injury, the patient developed progressive left hemiparesis. MRI of brain was suggestive of acute infarct involving right internal carotid artery territory. In accordance with the literature and as in present case, it would be emphasized that the patients who develop gross neurological abnormalities after blunt trauma to the head or neck, there should be a high index of suspicion of having sustained injury to the carotid arteries.

Massive bilateral chronic subdural haematoma after ventriculoperitoneal shunt

Large and increasing chronic subdural haematoma formation related to over functioning ventricular shunts is a well recognized entity, however it posses a difficult management challenge. Although the subdural haematoma in most instances they are space-filling, only exceptionally these lesions are space-occupying, however as in present case if there is presence of the mass effect evacuation is recommended.
