Objective: The objective of this study was to present the clinical, histopathologic, and radiographic findings of a unique case of intimal sarcoma (IS) embolus presenting as a large vessel occlusion causing an ischemic stroke without a detectable primary tumor site.

Methods: Extensive examinations, multimodal imaging, laboratory testing, and histopathologic analysis were used in evaluation.

Results: We report the case of a patient who presented with acute embolic ischemic stroke and was found to have IS based on a histopathologic evaluation of his embolectomy specimen. Subsequent comprehensive imaging studies failed to detect a primary tumor site. Multidisciplinary interventions including a course of radiotherapy were performed. The patient died of recurrent multifocal strokes 92 days after diagnosis.

Discussion: Meticulous histopathologic analysis should be conducted on cerebral embolectomy specimens. Histopathology may be useful in diagnosing IS.

Pulmonary artery intimal sarcoma has very poor prognosis, for which radical resection may be difficult. A 68-year-old man with pulmonary artery intimal sarcoma underwent bilateral pulmonary artery resection and replacement. At 31 months postoperatively, recurrence occurred at the anastomotic site of the right pulmonary artery.

A male in his seventies presented with lung cancer in the right lower lobe. The surgically resected specimen revealed a pleomorphic carcinoma featuring an adenocarcinoma component with lepidic, acinar, and papillary patterns, alongside a spindle cell component spreading along the pulmonary artery wall, resembling intimal sarcoma. The spindle tumor cells were positive for keratins, TTF-1, napsin A, and vimentin, but negative for p40, CK14, desmin, alpha-smooth muscle actin, CDK4, and MDM2.

Background: Intimal sarcoma is a rare and aggressive soft-tissue sarcoma with limited treatment options. We explored genomic profiles of intimal sarcoma to uncover therapeutic implications.

Materials And Methods: We analyzed tumor tissues from patients with intimal sarcoma who visited the Seoul National University Hospital (SNUH) using whole-exome, whole-transcriptome, and clinical next-generation sequencing (NGS), integrated with intimal sarcoma NGS data from two public cohorts.

A 43-year-old woman presented with dyspnea and cough, initially misdiagnosed as respiratory syncytial virus. Persistent symptoms led to pulmonary thromboembolism treatment, but worsening issues revealed recurrent pericardial effusion. Imaging and biopsy confirmed pulmonary artery intimal sarcoma, mimicking thromboembolism, and autoimmune disease, underscoring diagnostic challenges.

Intimal sarcoma of the aortic valve and ascending aorta: a case report.

J Thorac Dis

November 2024

Department of Cardiac Surgery, Beijing Anzhen Hospital, Capital Medical University, Beijing, China.

Background: Intimal sarcomas are rare tumors that typically affect the major vessels, such as the pulmonary artery and aorta, and are associated with a particularly poor prognosis. Intimal sarcomas found in the aorta are most commonly located in the abdominal section between the celiac artery and the iliac bifurcation. The descending aorta is involved in 30% of cases, while involvement of the ascending aorta is rare.
