1. In a case of multiple myeloma, bone scan will show
a. hot nodules b. cold nodules
c. diffuse increased uptake d. diffuse decreased uptake
2. Patient who had an Road traffic accident presents with presents with loss of consciousness CT shows multiple spotty hemorrhages and full basal cisterns-
a. Brain contusion b. Diffuse axonal injury
c. Subdural Hematoma d. Multiple infarcts
3. Tumour showing dural enhancement with a tail is:
a. Medulloblastoma b. Meningioma
c. Glioma d. Acoustic neuroma
4. A 25-yrs-old female presented with lower limb weakness, spasticity, urinary hesitancy, mid-dorsal intradural enhancing mass seen in MRI. What is the diagnosis?
Intradural lipoma b. Meningioma
c. Dermoid cyst d. Neuroepithelial cyst
5. A neonate presents with congestive heart failure, on examination enlarging fontanellae, bruit on auscultation, on USG shows midline hypoechoeic lesion, most likely diagnosis
A. Malformation of vein of galen B.Aqueduct stenosis
C. Arachnoid cyst D. Medulloblastoma.
6. Best investigation for temporal bone fracture is-
A) CT B) MRI C) X-RAY D) Ultrasound
The bone scan is usually normal in multiple myeloma because lytic lesions do not take up isotope.
Diffuse axonal injury (DAI) is a frequent result of traumatic deceleration injuries and a frequent cause of persistent vegetative state in patients. DAI is the most significant cause of morbidity in patients with traumatic brain injuries, which most commonly are the result of high-speed motor vehicle accidents. Typically, the process is diffuse and bilateral, involving the lobar white matter at the gray-white matter interface. The corpus callosum frequently is involved, as is the dorsolateral rostral brainstem. The most commonly involved area is the frontal and temporal white matter, followed by the posterior body and splenium of the corpus callosum, the caudate nuclei, thalamus, tegmentum, and internal capsule.
Meningiomas are usually dural-based tumors that are isoattenuating to slightly hyperattenuating. They enhance homogeneously and intensely after the injection of iodinated contrast material. Perilesional edema may be extensive. Hyperostosis and intratumoral calcifications may be present. The tumor compresses the brain without invading it. An enhancing tail involving the dura may be apparent on MRI.
Meningiomas are the second most common tumor in the intradural extramedullary location, second only to tumors of the nerve sheath. Meningiomas account for approximately 25% of all spinal tumors.MRI demonstrates the intradural extramedullary location of meningiomas. Lesions are usually isointense to spinal cord on both T1-weighted and T2-weighted images. Lesions are sometimes hypointense on T1-weighted images and hyperintense on T2-weighted images.
