# Unilateral alacrimia as a presenting symptom of Meckel’s cave tumour

## TL;DR

A rare brain tumor in the Meckel’s cave region caused dry eye symptoms by damaging the trigeminal nerve.

## Contribution

This case report highlights unilateral alacrimia as a rare and under-recognized presenting symptom of Meckel’s cave tumours.

## Key findings

- A 44-year-old male presented with tear deficiency due to a Meckel’s cave tumour.
- The tumour was found to harm the trigeminal nerve, leading to ocular symptoms.
- The case emphasizes the link between Meckel’s cave tumours and tear deficiency disorders.

## Abstract

Meckel’s cave tumour, a rare benign tumour originating from the Schwann cells surrounding the trigeminal nerve within the Meckel’s cave region, can present with a variety of clinical manifestations. We report a case of a 44-year-old male patient who presented with symptoms of tear deficiency, including dryness, ocular discomfort, and blurred vision. Diagnostic evaluation revealed the presence of a Meckel’s cave tumour harming the trigeminal nerve, leading to alacrimia. This case highlights the association between Meckel’s cave tumour and tear deficiency disorders.
