Cavernous Hemangioma

What is the most likely diagnosis? → Cavernous Hemangioma

Cavernous Hemangiomas

Composed of large, dilated vascular channels
More infiltrative than capillary type; frequently involve deep structures; do not spontaneously regress
Difficult to distinguish from malignant counterparts on imaging
Histology: sharply delineated but unencapsulated ; large cavernous blood-filled vascular spaces separated by connective tissue stroma
Intravascular thrombosis with dystrophic calcification common

Large, dilated, blood-filled vascular channels separated by connective tissue stroma
Infiltrative and poorly circumscribed — does NOT regress
Contains intravascular thrombi, dystrophic calcification, haemosiderin
Can be difficult to distinguish from malignancy on imaging
Association: Von Hippel-Lindau disease — cerebellar, brain stem, retinal, pancreatic, and hepatic cavernous hemangiomas

Association: Von Hippel-Lindau disease — cerebellar, brain stem, retinal, pancreatic, and hepatic cavernous hemangiomas (VASCULAR PATHOLOGY — Must-Know Comprehensive Notes)
| Cavernous hemangioma | Infiltrative; no regression; Von Hippel-Lindau; never biopsy percutaneously in liver | (VASCULAR PATHOLOGY — Must-Know Comprehensive Notes)
Benign Tumours — Capillary Hemangioma · Cavernous Hemangioma · Pyogenic Granuloma · Lymphangioma · Glomus Tumour (VASCULAR PATHOLOGY — Must-Know Notes)
| Cavernous hemangioma | Deep, infiltrative, no regression; von Hippel-Lindau association; brain = problematic | (VASCULAR PATHOLOGY — Must-Know Notes)
Most Common Benign: Cavernous Hemangioma ⭐ - Most common benign liver tumor - Usually incidental finding - Do NOT biopsy (risk of massive hemorrhage) ⭐ (Liver Histology & Physiology)
