A Primary Intramuscular Hydatid Cyst of the Proximal Thigh : A Rare Case Report

Primary intramuscular hydatid cyst of thigh is a very rare parasitic disease caused by Echinococcus granulosus. We present an unusual case of primary hydatid cyst in a 21-year old male who presented with slowly growing painless lump in the anteromedial aspect of proximal right thigh. Ultrasonography of the mass revealed a multiloculated cyst in the medial compartment of right proximal thigh without detectable primary any other location. MRI clearly displayed the lesion showing cystic mass with multiple well defined daughter cysts and diagnosis of hydatid cyst was made. The patient was treated surgically and cyst was excised. Macroscopic and microscopic histopathological examination confirmed the diagnosis of muscular hydatid cyst. Primary muscular hydatidosis is kept in mind in the differential diagnosis of a cystic mass of a skeletal muscle especially in endemic areas.TAJ 2011; 24(2): 142-144

Intramuscular small vessel arteriovenous malformation of the left ventricle in an asymptomatic adolescent: a case report and literature review

Primary vascular tumours of the heart are rare and heterogeneous in their presentation and classification. We present a primary intramuscular vascular malformation of the left ventricle in an asymptomatic 12-year-old girl. Characteristics on cardiac magnetic resonance imaging, specifically increased signal intensity on T2-weighted images, and marked contrast enhancement with gadolinium were suggestive of increased vascularity. Histologically, the mass was determined to be an intramuscular vascular malformation of the small vessel arteriovenous subtype. This represents one of a select few intramuscular vascular malformations of the left ventricle reported in children. Our patient remains completely asymptomatic and has had no change in the size and appearance of the mass after more than 30 months of follow-up.
