Case presentation: An 11 year old male child was referred to radiology department for investigation. On examination the child was short statured for its age, mandibular growth was not proper, large head with small chin, under developed fingers with skin tags were seen. On radiological examination, it was found that the mandible, phalanges were underdeveloped. The bone density showed hyperostosis in almost all bones. The child has been sent for genetic analysis. This case is being presented for its rarity. Conclusion: Literature review and management of the case to be discussed in view of its rarity. Conflicts of interest
Labbai Mohd Juned ∗ , K. Shyamkishore Seth GS Medical College, Parel, Mumbai, Maharashtra, India Introduction: The aortic arch is a continuation of the ascending aorta, being located in the superior mediastinum. Three branches, the brachiocephalic trunk, left common carotid artery and left subclavian artery usually arise from the aortic arch. Variations in the branching pattern of the aortic arch may occur as a result of developmental changes in the fusion and absorption of various pharyngeal arch arteries into the aortic sac. Case report: In routine dissection of undergraduate students at Seth GS Medical college, in a male cadaver, we found a variant of aortic arch branching pattern where the left vertebral artery arises from the arch of aorta in between the origin of the left common carotid artery and left subclavian artery. Where as the right vertebral artery took its normal origin from right subclavian artery. We also found that prevertebral segment of the artery was unusually long as left vertebral artery entered C4 transverse foramina instead of C6 transverse foramina of cervical vertebra. Detailed embryological basis of which will be explained in the poster. Conclusion: Since the vertebral artery is important for the posterior cerebral circulation, the anatomic and morphologic variations of the left vertebral artery are significant for diagnostic, surgical procedures and interventional radiology in the head and neck region.

Medical College and KEMH, Parel, Mumbai Case report: During routine dissection of a female cadaver, an unusual high origin of pronator teres muscle was found. These aberrant fibres arose from a tendinous arch. The tendinous arch was attached to the medial epicondyle and a small supracondylar process of humerus (Struther’s ligament). The median nerve and brachial artery was seen passing through the tunnel formed by the tendinousarch. Conclusion: Although the frequency of this variation is very low in human, the unusual high origin of pronator teres from the struther’s ligament should be considered in patients with symptoms of median nerve and brachial artery compression. Possible clinical symptoms include pain, paraesthesia, numbness and vascular symptoms. Conflicts of interest The authors have none to declare.

Vinay Kumar Palakkad Government Medical College, Kerala, India Background: Pyknodysostosis, also known as osteopetrosisacro-osteolytica or Toulouse-Lautrec syndrome, is a rare autosomal recessive bone dysplasia, characterised by osteosclerosis and short stature. This is a lysosomal disorder due to genetic deficiency in Cathepsin K which has been mapped to chromosome 1q21. Cathepsin K is essential for normal osteoclast function. The disease shows equal sex distribution with high parental consanguinity, having an incidence of 1.7 per 1 million births. There have been approximately 133 cases of this disorder reported in the medical literature so far and only 10 cases were from India.

However, the variation of terminal branches of brachial artery are uncommon. Materials and method: During routine dissection for undergraduates we came across anomalous arterial pattern in right and left upper limbs of 60 years old adult male cadaver. Observations: In the right upper limb, the ulnar artery presented high origin (3 cm above the insertion of coracobrachialis) from the anterior aspect of the brachial artery, which itself termi-
