Choroid Plexus Metastasis of Colon Cancer

Abstract

Fig. 1. Noncontrast CT scans reveal a large, well-deˆned, high-density mass within the inferior horn of the right lateral ventricle with extensive surrounding brain edema and a prominent midline shift. 155Magnetic Resonance in Medical Sciences, Vol. 2, No. 3, p. 155-158, 2003 CASE REPORT Choroid Plexus Metastasis of Colon CancerKazuhiro KITAJIMA 1 , Mizuho MORITA 1 , Masasi MORIKAWA 2 , and Kazuro SUGIMURA 3 * 1 Department of Radiology, 2 Department of Neurosurgery, Kobe National Hospital 3-1-1 Nishiochiai, Suma-ku, Kobe, Hyogo 654-0155, Japan 3 Department of Radiology, Kobe University Graduate School of Medicine, Kobe, Japan (Received May 8, 2003; Accepted July 30, 2003) This article presents an extremely rare case of solitary metastasis in the choroid plexus of the inferior horn of the right lateral ventricle three years after a colectomy for colon cancer. We discuss the current literature on this tumor together with the magnetic resonance (MR) imaging and computed tomography (CT)ˆndings.

Intraventricular metastases from rectal carcinoma: case report and literature review

“…A recent systematic review by Paolino et al noted gastrointestinal cancers account for 24.4% of scalp metastases, five cases of which were secondary to rectal carcinoma [ 7 ] . To our knowledge, there have only been four reported cases of intraventricular or choroid plexus metastases from a colon cancer origin, and no prior reports of one from a primary rectal cancer up to this point ( Table 1 ) [ 1 , 3 – 5 ] . All the cases described in this study or others have been secondary to the histologic diagnosis of adenocarcinoma.…”

“…Intraventricular metastases are a rare occurrence, particularly from a primary colorectal malignancy. There have only been four previously reported cases of intraventricular colon cancer metastases [ 1 , 3 – 5 ] .…”
