# Transverse Sinus Stenosis as an Underdiagnosed Cause of Chronic Headache: A Case Report

## TL;DR

This case report highlights transverse sinus stenosis as a rare but treatable cause of chronic headaches that is often overlooked in diagnosis.

## Contribution

The paper presents a case emphasizing the importance of considering TSS in patients with unexplained chronic headaches.

## Key findings

- Transverse sinus stenosis can cause chronic headaches and is often underdiagnosed.
- Early identification of TSS can lead to effective treatment and symptom resolution.
- High clinical suspicion is needed to diagnose TSS in patients with refractory headaches.

## Abstract

Transverse sinus stenosis (TSS) is an abnormality in the cerebral venous system in which the narrowing of the transverse sinus of the brain leads to obstructed cerebral venous outflow. It is an infrequent, incidental radiological finding. However, it is not uncommon among patients with chronic headaches of unclear cause, particularly those that remain unexplained after initial evaluation or those that are refractory to medical treatment. Its diagnosis frequently eludes the initial workup, and a high degree of suspicion should be maintained since its identification can lead to potentially curative treatment. This report describes the case of a 36-year-old female with a history of chronic headache who was found to have TSS. This paper discusses its etiology, pathophysiology, clinical presentation, radiological findings, and management.
