The aim of this article is to make radiologists and clinicians familial with the spectrum of cystic lesions in the abdomen. Mesenteric and omental cystic lesions are uncommon. One should be familiar with them as well as with other conditions that manifest as cysts. Initial step in diagnosing a cystic abdominal mass is to localize the organ of origin. Differential diagnosis includes enteric duplication cyst, enteric cyst, mesothelial cyst, non pancreatic pseudocyst, cystic mesothelioma, cystic teratoma, and urachal cyst. There is significant overlap in imaging features of abdominal cysts, which often require histological correlation to establish a final diagnosis. The main role of imaging is to document the nature of the abdominal mass and its origin.

OBJECTIVE To determine the effect of arthrotomy alone or in combination with osteotomy of the proximal portion of the tibia on blood delivery to the patellar tendon of dogs. SAMPLE 24 canine cadavers. PROCEDURES One hind limb from each cadaver was assigned to 1 of 4 treatment groups: medial arthrotomy (MA; MA group), lateral arthrotomy (LA; LA group), MA and LA with tibial tuberosity transposition (MALA group), and MA with tibial plateau leveling osteotomy (TPLO; TPLO group). The contralateral hind limb served as the control sample. Contrast solution (barium [33%], India ink [17%], and saline [0.9% NaCl] solution [50%]) was injected through an 8F catheter inserted in the caudal portion of the abdominal aorta. Limbs were radiographed to allow examination of vascular filling. The patella, patellar tendon, and tibial crest were harvested, radiographed to allow examination of tissue vascular filling, and fixed in 4% paraformaldehyde. Vessels perfused with contrast solution were counted in sections obtained from the proximal, middle, and distal regions of each patellar tendon. RESULTS Vessel counts did not differ significantly among the 3 tendon regions. Compared with results for the control group, delivery of contrast solution to the patellar tendon was significantly decreased in the MALA and TPLO groups but was not changed in the MA or LA groups. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that surgical procedures used to treat cranial cruciate injuries (ie, TPLO) and patellar luxation decreased blood delivery to the patellar tendon of canine cadavers, at least acutely.

Gummatous ulcer due to Treponematoses is quite rare in present era of potent antibiotics, increased social awareness and due to improvement in living standards of society .Better hygiene and improved medical care have contributed to containment of late benign syphilis or gummas. However, pockets of endemic treponematoses is still persisting in the underdeveloped, third world countries.Key words: Gummatous ulcer, treponematoses, antibiotics.DOI: http://dx.doi.org/10.3329/bjms.v10i3.7514BJMS 2011; 10(3): 209-210
