=== Pericardial Mesothelioma: Rare Heart Lining Cancer ===

Pericardial mesothelioma develops in the pericardium, the protective sac surrounding the heart, and represents less than 1% of all mesothelioma cases. This extremely rare form presents unique challenges because symptoms including chest pain, irregular heartbeat, difficulty breathing, and fatigue closely mimic common cardiac conditions.

The rarity of pericardial mesothelioma often delays accurate diagnosis, with some cases not identified until autopsy. Treatment options are limited due to the tumor's proximity to the heart, though palliative procedures like pericardiocentesis (draining excess fluid) can provide symptomatic relief. Median survival typically ranges from 6-10 months from diagnosis ([https://mesothelioma.net/mesothelioma-prognosis/ Mesothelioma Prognosis]).

From a legal perspective, pericardial mesothelioma cases often receive higher compensation due to the aggressive nature of the disease and limited treatment options. Virtually all pericardial mesothelioma cases are linked to asbestos exposure, and courts and trust funds generally recognize the devastating nature of this diagnosis ([https://dandell.com/mesothelioma/mesothelioma-case-worth/ Case Value Information]).
