    Cholesistografie en ultraklank in die diagnose van galstene
    (Health & Medical Publishing Group, 1982) Loxton, A. J.; Schulman, A.; Grove, H.
    Oral cholecystography and ultrasonography of the gallbladder were performed in 190 patients with the aim of diagnosing gallstones. At surgery gallstones were found in 23 patients and a roundworm in 1 patient. The results obtained with the two methods are comparable. Since neither radiation nor contrast agents are employed in ultrasonography, it is suggested that this be regarded as the primary special examination in the diagnosis of gallstones.

    Comparative morphological study of the pituitary gland by computed tomography and magnetic resonance imaging
    (Health & Medical Publishing Group, 1988) Loxton, A. J.
    A prospective study was undertaken to compare the morphology of the pituitary gland by computed tomography (CT) and magnetic resonance imaging (MRI) in 27 consecutive patients. CT is an accepted imaging modality but this study suggested that MRI has certain advantages. MRI is proposed as the imaging modality of choice for lesions of the pituitary gland.

    Hydatid cyst of the pancreatic tail : a case report
    (Health & Medical Publishing Group, 1984) Du Toit, D. F.; Loxton, A. J.; Laker, L.; Dreyer, J. F.
    A case of calcified hydatid cyst of the pancreatic tail is presented. The ultrasonographic and computed tomographic features of the lesion suggested the presence of a cystadenoma or a calcified hydatid cyst. Computed tomography proved the most useful investigation and accurately localized the lesion. A distal pancreatectomy and splenectomy were performed because on the basis of the results of pre-operative investigations and macroscopic operative findings, carcinoma of the pancreatic tail could not be ruled out with certainty. The patient made an uneventful recovery.

    Pseudosolid appearance of simple and echinococcal cysts on ultrasonography : a report of 2 cases
    (HMPG, 1983) Schulman, A.; Van Jaarsveld, J.; Loxton, A. J.; Grove, W. H.
    The 2 cases reported here indicate that on ultrasound examination uninfected simple and echinoccocal cysts can sometimes show a pseudosolid internal consistency like that of a neoplasm, probably owing to floating crystals or particles. This has important implications as far as further diagnostic and therapeutic measures are concerned. The presence of a regular and well-defined rim remains an important clue to the possible cystic nature of such lesions.

    Rectus sheath haematoma - a complication of anticoagulation therapy : a case report
    (Health & Medical Publishing Group, 1983) Du Toit, D. F.; Maritz, J.; Loxton, A. J.; Groenewald, J. H.
    A right-sided rectus sheath haematoma developed during heparin therapy for deep vein thrombosis. Computed tomography of the abdomen provided accurate pre-operative images of the size and extent of the haematoma, and surgical evacuation thereof resulted in uneventful recovery.

    Rekenaartomografiese diagnose van intratorakale lipoom : 'n gevalsbespreking
    (Health & Medical Publishing Group, 1984) Loxton, A. J.; Piek, C. J.
    A case of intrathoracic lipoma in a child is presented. The diagnosis was made before operation by means of computer-assisted tomography, a non-interventional procedure.

    Sonographic diagnosis of biliary ascariasis
    (1982) Schulman, A.; Loxton, A. J.; Heydenrych, J. J.; Abdurahman, K. E.
    In a prospective 6 month study, sonographic diagnosis of biliary ascariasis was made in 12 patients: In five, the diagnosis was confirmed by other means, mainly intravenous cholangiography. In three, such confirmation was not sought, but all had proven intestinal infestation. One possible and three definite false-positive diagnoses were made. There were no established false-negative diagnoses. The echogenic, nonshadowing images of the worms were seen in the main bile duct and/or gallbladder as single strips (on one occasion with its digestive tract seen as an anechoic 'inner tube'), as multiple strips giving a spaghettilike appearance, as coils, or as more amorphous fragments. Follow-up sonograms were obtained in six patients and showed expulsion of the worms by medical treatment.
