A spiral cystic fibroma originating from left ventricular fascicular muscle: a case report

BACKGROUND: In adults, cardiac fibromas are fairly rare, mostly round in shape, and few cases of ventricular fibromas of other morphology have been reported. CASE PRESENTATION: We report a case of a 47-year-old male patient admitted with recurrent nocturnal paroxysmal dyspnea, diagnosed by transthoracic cardiac ultrasound, transesophageal ultrasound, and computed tomography (CT) as a left ventricular occupancy with a spiral shape resembling a conch with a fixed base and a free distal end. CONCLUSION: This case reports a rare but noteworthy morphological features of the adult uncommon ventricular tumor pathological type. Furthermore, the patient had no notable postoperative issues and was followed up on for a year following surgery, with no residual tumors or arrhythmias discovered during the examination.
