A 51-year-old male presented to our hospital's outpatient department with complaints of swelling in left thigh since six year. The swelling was insidious, gradually progressive in size, not associated with pain, fever or discharge. There was no history of weight loss or loss of appetite. There was no history of any antecedent trauma or any direct impact on the area. Medical history revealed no bleeding diathesis or anticoagulant therapy.Physical examination revealed a well defined fluctuant swelling in the lateral aspect of left thigh, measuring 17x10x5 cm in size. The swelling was globular in shape with smooth surface with no tenderness and no local rise in temperature. The lesion was cystic in consistency and compressible with smooth edges and the overlying skin was smooth and could be pinched. The lesion could be moved over the underlying muscles. Distal neurovascular status was normal. Ultrasound revealed a large subcutaneous cystic lesion showing mobile internal echoes, extending from hip to the knee region. MRI revealed a well defined unilocular cystic lesion measuring 20x10x6 cm which was hyperintense on both T1-weighted and T2-weighted sequences, seen along the left proximal fascia lata, in close proximity to underlying vastus lateralis and gluteus maximus muscles with maintained intervening fat planes. Fluidfluid level with dependent hypointensity was seen within the lesion. The cyst showed a thin smooth capsule which was hypointense on all sequences, and multiple small hypointense mural nodules were seen projecting into the lumen [Table /Fig-1a Morel-lavallee lesion (MLL) represents post traumatic subcutaneous cyst generally overlying bony prominences like greater trochanter, lower back, knee and scapula. A 51-year-old man presented with a swelling in left thigh since six years which was insidious in onset, gradually progressive in size and not associated with pain, fever or discharge. There was no history of trauma or any associated constitutional symptoms. Since there was no history of trauma recalled by the patient the clinical dilemma was between soft tissue sarcoma and cold abscess. We report a case of slow growing painless mass lesion of thigh, diagnosed on Magnetic Resonance Imaging (MRI) as morel lavallee lesion and describe its salient imaging features with treatment options.[

Abdominal cocoon, also known as sclerosing encapsulating peritonitis, represents a rare entity where a variable length of the small bowel is enveloped by a fibrocollagenous membrane giving the appearance of a cocoon. It may be asymptomatic and is often diagnosed incidentally at laparotomy. We present a rare case of abdominal cocoon due to abdominal tuberculosis.
