The fat pad in dermis fat grafts.
BACKGROUND: Dermis fat grafts are used in orbital reconstruction in a variety of procedures. However, there have been few controlled studies testing their effectiveness. This is a prospective study on 40 patients. METHODS: Primary and secondary orbital dermis fat grafts were evaluated with regard to the long-term cosmetic results of two thicknesses, 10 and 20 mm, of fat pad, keeping all other parameters as constant as possible. Adequacy of the socket, lid anomalies; superior sulcus deformity, exophthalmometry, and motility of the prosthesis were assessed periodically. CONCLUSION: There was a significantly lower incidence of enophthalmos and superior sulcus deformity with the use of a fat pad thickness of 20 mm, without any compromise in the motility of the prosthesis or take of the graft.
Unusual complications of pancreatitis.
The computed tomography (CT) appearances of varying grades of severity of acute pancreatitis, and its complications, have been described. Bodywall ecchymosis in the periumbilical region (Cullen's sign) and loins (Grey Turner's sign), though rare, are frequently mentioned in the clinical literature. Massive, exclusively retroperitoneal, involvement is also exceedingly rare. Computed tomography depiction of these signs is sparsely documented. The CT documentation, with clinicosurgical correlation, of two cases of severe acute pancreatitis with these unusual complications, is presented.
CT appearances in macronodular hepatosplenic tuberculosis: a review with five additional new cases.
Pseudotumoral or macronodular hepatosplenic tuberculosis (HSTB) is rare. Only 31 cases have been documented in imaging literature so far. Presented is the clinico-imaging review with five additional new cases of this uncommon variety. Due to nonspecific wide spectrum of imaging appearances, biopsy is mandatory in almost all cases. Clinical recovery and resolution of lesions on imaging may not be directly proportional.
