What causes a Superscan?
Common causes include malignancies like prostate cancer, breast cancer, and lung cancer. [1,2,3,4] Hematological conditions like leukemia, lymphoma, myelofibrosis, Waldenstrom’s macroglobulinemia have been reported to be associated with a superscan.
Can vertigo be caused by breast cancer?
In addition to 8% occurrence of posterior fossa metastasis, other possible causes for vertigo in breast cancer survivors consist of vascular insufficiency, hyperlipidemia and labyrinthine lesion.
Can vertigo be seen on CT scan?
Conclusions: A large number of head CT and MRI are made in patients with vertigo and dizziness. A clinical suspicion is recommended from the anamnesis and exploration to make a good selection of test to request. In more than 90% of cases, radiological findings are not shown in relation to vertigo.
What is a bone scan Superscan?
Superscan is defined as “a bone scan which demonstrates markedly increased skeletal radioisotope uptake relative to soft tissues in association with absent or faint renal activity (absent kidney sign).” Superscan was first described by Osmond et al.
What does increased activity in bone scan mean?
For instance, a bone scan shows areas of increased bone activity, such as bone metabolism, a continuous process that forms new bone and breaks down existing bone. Areas that exhibit higher-than-normal bone formation may indicate a bone fracture.
Is Vertigo a symptom of cancer?
Feeling dizzy or lightheaded is a possible side effect of cancer and its treatment. You might feel as if you are about to lose your balance or that the room is spinning around you. You might also feel like you are about to faint. Dizziness may get worse when you stand up, walk, climb stairs, or simply move your head.
Does vertigo show up on MRI?
MRI Scans. In some people with vertigo—in particular those who also have hearing loss—doctors may recommend an MRI scan to obtain a closer look at the inner ear and surrounding structures.
Why would the scan show bone abnormalities?
Your doctor may order a bone scan if you have unexplained skeletal pain, a bone infection or a bone injury that can’t be seen on a standard X-ray. A bone scan can also be an important tool for detecting cancer that has spread (metastasized) to the bone from the tumor’s original location, such as the breast or prostate.
Are there superscans on a bone scintigraphy?
Superscans on bone scintigraphy have been described mostly in metastatic and metabolic bone diseases, with different patterns and appearances of radiotracer uptake. This is a report of bone scintigraphy demonstrating superimposed metastatic and metabolic superscan in a patient with prostate cancer, who subsequently developed renal osteodystrophy.
What are the causes of the SuperScan phenomenon?
Causes of superscan are as follows: renal osteodystrophy; osteomalacia; hyperparathyroidism; hyperthyroidism; diffuse skeletal metastases; myelofibrosis; haematological malignancy; extensive Paget’s disease.
Is it good to have a CT scan for dizziness?
For the more common complaints of dizziness, which are usually lightheadedness, positional vertigo or isolated dizziness, there is little value in performing a CT Scan. A second, but just as important factor to consider, is the sensitivity of CT scans in detecting cerebellar stroke (presumably the main concern of the ordering physician).
What does differential diagnosis of ” Super scan ” mean?
Differential Diagnosis of a “Super Scan” Appearance on Bone Scan Super scan (superscan) refers to the diffuse skeletal uptake of MDP with resultant low or absent activity in the kidneys and bladder and high ratio of bone to soft tissue activity. Focal lesions in the skeleton may be obscured in some cases.
