The current approach to the diagnosis of vascular anomalies of the head and neck: A pictorial essay

Throughout the years, various classifications have evolved for the diagnosis of vascular anomalies. However, it remains difficult to classify a number of such lesions. Because all hemangiomas were previously considered to involute, if a lesion with imaging and clinical characteristics of hemangioma does not involute, then there is no subclass in which to classify such a lesion, as reported in one of our cases. The recent classification proposed by the International Society for the Study of Vascular Anomalies (ISSVA, 2014) has solved this problem by including non-involuting and partially involuting hemangioma in the classification. We present here five cases of vascular anomalies and discuss their diagnosis in accordance with the ISSVA (2014) classification. A non-involuting lesion should not always be diagnosed as a vascular malformation. A non-involuting lesion can be either a hemangioma or a vascular malformation depending upon its clinicopathologic and imaging characteristics.

Abdominal cocoon - a rare case of intestinal obstruction: a report of two cases

We present the imaging findings in 2 adolescent girls with abdominal cocoon formation, a rare cause of intestinal obstruction. It may be primary/idiopathic or secondary in nature and is characterized by small bowel encapsulation. Familiarity with the imaging findings and a high index of suspicion helps in reaching the diagnosis pre-operatively in this rare condition and hence planning surgical management
