Pheochromocytoma rupture led to spontaneous resolution of hypertension and hyperglycemia. Histopathology confirmed the rupture, revealing hemorrhagic necrosis and viable tumor cells, offering rare insights into this event.
Area of Science:
- Endocrinology
- Radiology
- Pathology
Background:
- Pheochromocytoma is a rare adrenal tumor causing hypertension and other symptoms due to excess catecholamine production.
- Documented cases of pheochromocytoma rupture with detailed clinical, imaging, and histopathological correlation are scarce.
Observation:
- A patient with uncontrolled hypertension and hyperglycemia presented with symptoms suggestive of pheochromocytoma.
- Abdominal CT revealed an adrenal mass; however, after spontaneous left flank pain, imaging showed changes consistent with tumor rupture, and hormone levels normalized.
Findings:
- Computed tomography (CT) demonstrated evolving changes in the adrenal mass, indicative of rupture and hemorrhage.
- Histopathological examination of the resected tumor confirmed pheochromocytoma with widespread hemorrhagic necrosis and viable tumor cells at the margins.
Implications:
- This case highlights the dynamic changes in imaging and hormone levels associated with pheochromocytoma rupture.
- Understanding these changes is crucial for accurate diagnosis and management of this rare clinical presentation.

Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
