Background:
Solitary extramedullary plasmacytoma (SEP) is a plasma cell neoplasm located outside the bone. It is rarely observed in the intracranial area. It is very difficult to diagnose this condition radiologically before surgery. In addition, dural SEP is usually misdiagnosed.
Case Description:
We report a case of plasmacytoma that presented as altered mental status after head trauma, located in the subdural area. We also describe its differential diagnosis and treatment by total removal and adjuvant radiotherapy. The 66-month follow-up findings showed distant plasmacytoma development, which was treated with radiotherapy alone.
Conclusions:
Some pathological entities should be considered in the differential diagnosis of acute subdural hematomas. Furthermore, to the best of our knowledge, we report the first case of dural SEP mimicking acute subdural hematoma.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Acute Respiratory Failure-V
Ensure that patients are monitored continuously for their response to therapy, including changes in...
