# Spontaneous Subdural Hematomas as Initial Presentation of Acquired Coagulopathy: A Case Report

## TL;DR

A 64-year-old woman with a rare bleeding disorder presented with headaches and neck pain due to a spontaneous subdural hematoma.

## Contribution

This case report presents a rare initial presentation of acquired coagulopathy in a patient with an autoimmune disorder.

## Key findings

- The patient had an isolated prolongation of aPTT on coagulation tests.
- Spontaneous subdural hematoma was identified as the initial manifestation of acquired coagulopathy.
- The case emphasizes the importance of a thorough diagnostic approach in similar presentations.

## Abstract

The evaluation of coagulopathies can be challenging due to the extensive variety of etiologies. This can be particularly complicated in patients with concomitant autoimmune disorders. In this case, a 64-year-old woman presented with intractable headaches and neck pain for two weeks. Her coagulation tests revealed an isolated prolongation of activated partial thromboplastin time (aPTT). This case highlights the diagnostic approach and summarizes management considerations in patients with similar presentations.
