# An Unusual Cause of Abdominal Pain: Mesenteric Lymphadenopathy Secondary to Sarcoidosis Without Pulmonary Involvement

## TL;DR

This paper presents a rare case of sarcoidosis affecting the gastrointestinal tract and mesenteric lymph nodes without lung involvement, successfully treated with methotrexate.

## Contribution

The novelty lies in the rare presentation of sarcoidosis with GI and lymph node involvement but no pulmonary symptoms.

## Key findings

- GI sarcoidosis can present with mesenteric lymphadenopathy and no pulmonary involvement.
- Methotrexate was effective in treating this rare case of sarcoidosis.
- Biopsy is essential for diagnosing sarcoidosis in the GI tract.

## Abstract

Sarcoidosis is a systemic disease that affects multiple organs in the body but rarely affects the gastrointestinal (GI) tract. The symptoms of GI sarcoidosis may be nonspecific or silent. Often, it is discovered on computed tomography (CT) or esophagogastroduodenoscopy (EGD), and a biopsy is needed for diagnosis. Initial management is typically with prednisone; however, here, we present a rare case of GI sarcoidosis with mesenteric lymphadenopathy in the absence of pulmonary involvement, diagnosed via biopsy and treated successfully with methotrexate.
