Transverse sinus thrombosis presenting with acute hydrocephalus: a case report

Headaches are common in clinical practice, but sudden onset or worsening symptoms can signal serious underlying conditions. While many headaches are benign, some are linked to life-threatening causes like cerebral venous thrombosis. Traditional diagnostic approaches often focus on arterial issues, but venous pathologies remain under-recognized. Prior research has shown that dural sinus thrombosis can present with nonspecific symptoms, delaying diagnosis. No prior work had resolved the frequency of this condition in patients with new-onset headaches. That uncertainty drove the need for better diagnostic awareness. This gap motivated clinicians to explore rare but critical conditions like transverse sinus thrombosis. No standardized guidelines exist for imaging in such cases. This lack of clarity complicates clinical decision-making.

The aim of this case report is to highlight the importance of considering transverse sinus thrombosis in patients presenting with acute headaches and neurological symptoms. The specific problem is the diagnostic challenge of distinguishing rare venous infarcts from more common conditions. The motivation stems from the potential for delayed diagnosis to worsen patient outcomes. This case illustrates how imaging can reveal unexpected findings like cerebellar venous infarct. The authors propose that clinicians should maintain a broad differential diagnosis when evaluating new headaches. No prior work had resolved the diagnostic value of MRI in such cases. This case report provides a real-world example of the condition’s presentation. The goal is to raise awareness among healthcare providers about this rare but treatable cause of headache.

The study involved a single patient case with clinical and imaging data. The design focused on retrospective analysis of symptoms and diagnostic findings. Tools used included MRI and CT scans to assess brain structures. The approach combined clinical evaluation with radiological interpretation. No experimental interventions were performed. The patient’s history and physical examination were documented. Imaging findings were compared with known patterns of venous infarction. The case was reviewed to determine the role of transverse sinus thrombosis in the patient’s symptoms.

The patient presented with a 10-day headache and acute hydrocephalus. MRI revealed a tumefactive lesion in the posterior fossa. Further imaging confirmed a cerebellar venous infarct. The cause was identified as unilateral transverse sinus thrombosis. No other common causes of headache were found. The diagnosis was confirmed through radiological findings. The patient’s symptoms aligned with known patterns of venous infarction. The case supports the need for considering dural sinus thrombosis in headache evaluation.

The authors propose that transverse sinus thrombosis should be included in the differential diagnosis of new-onset headaches. The findings suggest that acute hydrocephalus can result from cerebellar venous infarction. The case supports the idea that MRI is a valuable tool in diagnosing such conditions. No prior work had resolved the frequency of this condition in clinical practice. The authors suggest that clinicians should consider rare causes when symptoms persist. The study does not claim that this is the most common cause of headache. The implications are limited to the diagnostic approach in this specific case. The authors do not propose new treatment guidelines based on this single case.
