The serological tests were within normal limits. chest x-ray showed a rounded regular density in the right lower lobe (Fig. 1).
Chest and abdominal CT scan with contrast: A: chest CT shows the 10*8 cm cyst in the right lower lobe of the lung(black star). B:abdominal CT reveals the small 1.5*2 cm cyst in the right lobe of the liver(black arrow).

Computed tomography confirmed the presence of a 10 x 8 cm cystic mass within the lower lobe of the right lung (Fig. 2A), a 5.5 x 4.5 cm cystic mass within the muscular components over the left scapula, and a 2 x 1.5 cm cystic mass within the right lobe of the liver (Fig. 2B).
Chest MRI: C: T2 weighted image(coronal section) shows two high sign intensity cystic lesions, one 5.5*4.5 cm within the thickness of left trapezius muscle(white arrow) and the other 10*8 cm in the right lower lobe of the lung(white star). D: T1 weighted image(axial section) reveals low sign intensity cystic lesion within left trapezius muscle.

T1-weighted MRI images of the left shoulder cyst revealed a low signal intensity cystic mass with a low intensity rim and high signal intensity on T2-weighted images within the thickness of left trapezius muscle (Fig. 3C and D).

The right lung lesion was approached firstly through a right thoracotomy in the 5th inter-costal space, and the 10 x 6 cm cystic mass in the right lower lobe (Fig. 4) was excised by means of aspiration, injection of 20% hypertonic saline and re-aspiration and then the germinal membrane then was enbloc excised.

A 5 x 4 cystic mass was found within the thickness of the left trapezius muscle, and was enucleated taking care not to induce any leak (Fig. 5) and the remainder cavity was closed with 2.0 vicryl stuture.
