We report a case of a 21-year-old male with stage IIIB sigmoid colon adenocarcinoma who experienced atypical chest pain post-adjuvant chemotherapy with Capecitabine (5-FU prodrug). Evaluation revealed an unexpectedly detected interventricular septum hemangioma. Due to the vasospasm effect of chemotherapy presenting with semi-ischemia, conservative management was chosen for atypical presentation.

Human hydatidosis occurs mainly as a result of infection with the larvae of Echinococcus granulosus. Cardiac echinococcosis is an uncommon disease and the interventricular septum is rarely involved. This article is a review of all of the literature related to hydatid cyst in the interventricular septum included in the PubMed database. Forty-five cases reported between 1964 and 2019 were identified.

Aneurysm of the Membranous Septum (AMS) is a rare cardiac disease, mostly associated with other cardiac anomalies, very rare in the absence of other congenital heart defects. A prompt diagnosis is important, due to severe potential complications, but remain challenging. Most of the cases were earlier diagnosed using ventriculography, but, with the availability of echocardiography and cardiovascular magnetic resonance (CMR), this disease can be accurately assessed non-invasively. We report a case of a 62 years old female patient, without other cardiac congenital disease, who was incidentally diagnosed, by means of CMR with a true and isolated AMS. Our report underlines CMR usefulness in AMS diagnosis, thanks to accurate evaluation (both morphologic and functional) provided by this diagnostic tool, which is able to demonstrate clearly the presence of AMS (aneurysm of the membranous septum) and depict its features.
