“…The conjunctiva, eyelid, orbital connective tissue and lacrimal gland are most frequently involved [23]. Primary extraocular muscle lymphomas are rare, it accounts for about 0.1% and 8.7% of all extranodal lymphomas [24,25]. In most cases extraocular muscle involvement is due to infiltration of extramuscular masses [26,27].…”

“…The most typical location of involvement is the superior-lateral quadrant [28]. The rectus muscles are more frequently affected, especially the superior rectus and lateral rectus muscles, but the lacrimal gland and eyelid in this quadrant may also be infiltrated [14,25,28]. Advanced cases can show sinus bone erosion and intracranial spreading.…”

Purpose of Review To provide the radiologist with tools to recognize findings atypical for Graves’ ophthalmopathy and differentiate between the most important and common alternative causes of extraocular muscle enlargement on CT and MR imaging. Recent findings We introduce five ‘red flags’ representing features that are atypical for Graves’ ophthalmopathy: unilateral disease, atypical pattern of muscle involvement, adjacent structure involvement, restricted diffusion, and absence of pain. Summary About 95% of the cases with extraocular enlargement are due to Graves’ ophthalmopathy, other causes are less well known and recognized. The ‘red flags’ may aid in recognizing and suggesting alternative diagnoses.

“…Tumours arising from the lymphatic structures give rise to lymphoma and the retroperitoneal position is said to be the most common location [19,20]. The retroperitoneal lymphoma has been noted to have greater tendency for forming composite soft tissue masses than lymphomas located in other parts of the body [21].…”

Retroperitoneal tumours are an aggregate of multiple types of neoplastic lesions with a preponderance of tumours of mesenchymal origin.Other histological types such as Lymphoma, are reported to be commoner now. Retroperitoneal tumours are generally rare and clinical diagnosis is often difficult due its cryptic location. It is often diagnosed incidentally following abdominal radiological studies or following complications. The most common complication being an extrinsic compression, particularly, on the retroperitoneal structures; such as the ureters, duodenum or the major abdominal vessels. It may also present as a vague abdominal pain or chronic bowel obstruction like our index patient. Abdominal CT Scan is the most sensitive tool of diagnosis and complete surgical excision often, an enbloc excision with involved adjoining organs offers the best chance of cure. Adjuvant chemotherapy, radiotherapy or chemo-radiation improve disease free interval and overall survival. The mainstay of retroperitoneal lymphoma is however a cytotoxic chemotherapy or more recently Rituximab combination therapy. We present a case of a huge retroperitoneal large B-cell Lymphoma presenting as chronic small bowel obstruction.
