Abstract:
The finding of intracranial, extramedullary plasmacytoma is rare in multiple myeloma, especially with dural involvement. Meningioma remains the most common intracranial extra-axial mass. We report a case of a 39-year-old male who presented with intracranial, extra-axial mass found later to be dural plasmacytoma and additional multiple lesions on skeletal survey, leading to a diagnosis of multiple myeloma. The objective of this case is to increase awareness of the possibility of dural plasmacytoma as a differential diagnosis of meningioma and a harbinger of multiple myeloma. Magnetic resonance imaging plays a vital role in the detection of additional lesions in individuals while excluding multiple myeloma.
Insights
Intracranial dural plasmacytoma, a rare finding in multiple myeloma, can mimic meningioma. Early detection via MRI is crucial for diagnosing this condition and underlying multiple myeloma.
Area of Science:
- Neurology
- Oncology
- Radiology
Background:
- Intracranial extramedullary plasmacytoma is a rare manifestation of multiple myeloma.
- Dural involvement by plasmacytoma is particularly uncommon.
- Meningioma is the most frequent intracranial extra-axial tumor, often presenting similarly.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
Deformation of Member under Multiple Loadings
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...
Multiple Voltage Sources
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
Batteries are...
Multiple Comparison Tests
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
Multiple Bar Graph
Each bar or column in the multiple bar graph represents a data value. These graphs are used primarily in interrelating two or more sets of data. The categories of different kinds of data are listed along the horizontal or x-axis, whereas...
