Primary hepatic leiomyosarcoma (PHLS): A case report and literature review
Nobukata Kazawa and Yoriko Yamashita
We encountered a rare case of HLMS.US and plain CT showed ill-defined para-caval hepatic tumor in the caudate lobe. The contrast enhanced CT showed a relatively poorly enhanced tumor with non-enhanced area suggesting necrosis. On MRI, the tumor presented with low signal intensity on T1 in-phased image and heterogeneously high signal intensity on T2WI. On T1-opposed-phase, the tumor showed the slight elevation of the signal compared with T1 in -phased image. This phenomenon suggested shortening of T2* effects caused by faint hemorrhage .On dynamic enhanced MRI, the lesion showed gradually mild enhancement from the arterial to the venous phase with some necrotic area. By the CT-guided biopsy, the diagnosis of leiomyosarcoma with faint hemorrhage was made on immunohistochemical stain.
