Delayed insulinoma diagnosis is a challenge, often mistaken for epilepsy. This case highlights the need for reassessing refractory seizures to identify rare causes like insulinoma for better patient outcomes.
Area of Science:
- Endocrinology
- Neurology
- Oncology
Background:
- Insulinoma diagnosis is often delayed due to non-specific symptoms.
- Symptoms can be misattributed to other conditions, leading to prolonged misdiagnosis.
Purpose of the Study:
- To report a case of insulinoma presenting with refractory seizures.
- To emphasize the importance of considering insulinoma in atypical neurological presentations.
Main Methods:
- Clinical presentation of a 64-year-old male with misdiagnosed epilepsy.
- Diagnostic workup including starvation test, pancreatic enhancement CT, MRI, and pathological examination.
- Surgical tumor removal and symptom assessment.
Main Results:
- The patient experienced recurrent seizures for 4 years due to misdiagnosis.
- Diagnostic tests confirmed insulinoma.
- Surgical removal of the tumor led to symptom improvement.
Conclusions:
- Insulinoma can manifest with unusual neurological symptoms like seizures.
- Accurate diagnosis requires careful reassessment of refractory seizures and advanced imaging.
- Early identification and surgical treatment of insulinoma are crucial for resolving symptoms.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
Hypoglycemia and Glucagon

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
