The increased pressure presumably results in malformation of the renal parenchyma and the development of numerous cortical cysts, espe- cially beneath the capsule. The nephrogram is composed of many streaky collections of contrast material radiating from the calyces to the periphery.

Splenic impression Flattening of the upper lateral margin of the left The impression on the renal contour is probably kidney. There is often an associated bulge lower on the lateral margin of the kidney (dromedary hump). May be multifocal or sis and atrial fibrillation, infective endocarditis, or bilateral. Chronic atrophic Cortical depression overlying a retracted papilla, Related to chronic pyelonephritis and vesico- pyelonephritis whose calyx is secondarily smoothly dilated. Focal areas of parenchymal loss and calyceal clubbing in the upper pole of the right kidney. Note the tortuosity and rapid tapering of inter- lobar arteries and their branches that is characteristic of arteriolar nephrosclerosis. Usually a normal thickness of renal parenchyma between the under- lying calyx and the overlying renal capsule. Most commonly develops at the junction of the middle and upper thirds of a duplex kidney. There is flattening of the upper two-thirds hyma in the suprahilar area impresses the upper infundibu- of the lateral border of the left kidney, most likely from splenic lum laterally.

More commonly the patient complains of an abnormal swelling when he flexes his elbow due to bunching of the biceps muscle cheap omnicef 300mg visa virus free download. The presenting complaint and the signs are similar to the rupture of the biceps tendon described above. In this condition the patient complains of pain and difficulty in abducting and extending the thumb. On examination a bulge is detected on the said tendons over the radial styloid process. With continued effort he suddenly becomes successful in forcing the swollen tendon through the constricted sheath and as soon as it is done the finger becomes extended quickly and abruptly like a trigger of a pistol. The only difference is that the cause is not only thickening of the flexor retinaculum but also some other pathology such as rheumatoid arthritis involving the synovial sheaths of the flexor tendons or dislocation of lunate bone which compresses on the contents of this osseo-fibrous canal, mainly the median nerve, also exits. The main complaint of the patient is some sort of difficulty in flexing fingers with pain and neurological deficits of the median nerve, e. Flexion movement of the fingers will be painful and conduction studies on the median nerve will demonstrate a delay at the carpal tunnel. There may be nodules in the fascia or in the subcutaneous tissue indicating excessive fibrous tissue activity. This condition mostly affects the medial part of the palmar fascia in which the ring finger and less often the little finger become flexed. This is due to the fact that the extensions of the palmar fascia are attached to the proximal as well as middle phalanges. Repeated trauma which was previously incriminated as the cause of this condition has been discarded due to the fact that it often involves the persons who do not inflict trauma so repeatedly in the palm. A ganglion on the dorsal aspect of the wrist in relation with the extensor tendon of the finger. On examination, there is thickening of the medial aspect of the palmar fascia with firm nodules within the fascia or in the subcutaneous tissue. The overlying skin is more or less fixed to the fascia and there is flexion deformity of the ring and the little fingers. It may be due to a leakage in the capsule or the tendon sheath following trauma and subsequent encapsu-lation with fibrous tissue or it may be due to mucoid degeneration of the fibrous sheath. On examination, a tense and cystic swelling will be revealed in relation to a capsule of the joint or a tendon sheath. When it originates from a tendon sheath it can be moved sideways slightly but not at all along the length of the tendon particularly when Fig. Monostotic fibrous dysplasia, though rare, is chiefly a disease of adolescents but may remain symptomless till the bone breaks. Osteogenesis imperfecta (Brittle bones) Epiphysis : congenita presents with multiple fractures, dwarfism Epiphysitis Osteoclastoma and deformities since birth; whereas osteogenesis imperfecta tarda presents later near 10 years of age. Nearly all benign bone tumours occur in Chondroma Osteogenic sarcoma adolescent and in young adults; Osteoclastoma occurs Bone cyst between 20 and 30 years of age. Primary malignant bone tumours mainly occur in young people; Osteosarcoma occurs between 15 and 30 years of age; Multiple myeloma occurs late — 30 to 50 years. Diaphysis : Syphilitic osteitis Secondary carcinoma of bone is seen in old age above Ewing’s tumour 40 years. Spontaneous development of swelling is most likely to be seen in cases of bone tumours. Acute onset with high rise of temperature and toxaemia is a feature of acute osteomyelitis. In chronic osteomyelitis the onset is usually insidious, but acute exacerbation of chronic osteomyelitis is not uncommon. Malignant tumours grow very rapidly and the history is relatively short since the patient had discovered the swelling. But in bone the peculiar feature is that the malignant growth osteosarcoma presents with pain first and swelling later on. Otherwise the tumours whether they are benign or malignant are painless to start with. In malignant bony tumours the duration is relatively short in comparison to the benign bony swellings. In diaphyseal aclasis there will be multiple swellings arising from the metaphyses of different bones affecting a young boy. In osteosarcoma the skin over the swelling remains tense, glossy with dilated veins. In tuberculous osteomyelitis cold abscess will lead to a swelling in the beginning and later on sinus formation. The tuberculous sinus will reveal its characteristic features like undermined edge and bluish margin, whereas in chronic pyogenic osteomyelitis there will be sprouting granulation tissue which indicates presence of sequestrum at the depth. There may be paresis neous veins in case of osteo- due to involvement of the nerves by the bony swellings. Sometimes acute osteomyelitis may destruct the epiphyseal cartilage thereby hampering the growth of that particular bone. Genu valgum or genu varum may be the result of asymmetrical destruction of the lower epiphyseal cartilage of the femur. Shortening or lengthening of the bone — may sometimes be seen following infection of the bone which either provokes the growth of the bone or destroys the epiphyseal cartilage and hence retards the growth of the bone. In osteosarcoma the consistency varies — somewhere bony hard, somewhere firm and may be even soft at places. Being a bony swelling its consistency should also be bony hard, but the condition is so painful and tender that the clinician hardly reaches the bone during palpation and can only palpate the soft tissues overlying the bone which pits on pressure. Telangiectatic osteosarcoma, aneurysmal bone cyst, occasionally highly vascular osteoclastoma, very rarely haemangioma of bone and highly vascular metastatic carcinomas from thyroid cancer and renal adenocarcinoma. Note the foot drop on the right side due to involvement of the lateral popliteal nerve by an osteoma at the head of the fibula. These are commonly seen in chronic pyogenic osteomyelitis and tuberculous osteomyelitis. In case of the former there will be sprouting granulation tissue at the orifice of the sinus indicating presence of sequestrum in the depth and in case of the latter the ulcer will be undermining with bluish newly growing epithelial edge. In fact sometimes this fracture becomes the first presenting symptom of the primary carcinoma which may be in the lung, kidney, breast, prostate, thyroid etc. Shortening will be found when the epiphyseal cartilage is destroyed and the bone may be lengthened when the metaphysis is included within the zone of hyperaemia. Osteosarcoma, which mainly starts from the metaphysis, does not invade the epiphyseal cartilage until late and hence the joint remains unaffected. Swellings of the distal limb and venous engorgement may be due to pressure on the neighbouring veins. In tuberculous osteomyelitis general examination must be made to exclude pulmonary tuberculosis and lymphadenitis. Enquiry must be made whether the patiert had cough, evening rise of temperature, pain in the chest, haemoptysis, etc.

Undifferentiated abdominal Bizarre masses of calcification that do not Patients with this condition have large soft-tissue malignancy conform to any organ. Meconium peritonitis Multiple, small calcific deposits scattered widely Chemical inflammation of the peritoneum throughout the abdomen in a newborn. Meconium peritonitis usually results from perforation in utero secondary to a congenital stenosis or atresia of the bowel or to meconium ileus. The granular, sand-like calcifications represent metastatic spread throughout the abdomen. The calcifications are located in masses of fibrous tissue surrounding the oil droplets. Clinically, oil granulomas can produce hard palpable masses that simulate carcinomatosis or cause intestinal obstruction. Predisposing conditions include atrophic gastritis, pernicious anemia, gastric polyps, partial gastrectomy, and Ménétrier’s disease. Coronal reformat- ted image shows an elevated lesion in the greater curvature that protrudes less than 5 mm into the lumen. The subtle irregularities of the mucosal surface corresponded to ulcers at histology. However, most patients with lymphoma have adenopathy, and the nodes are usually bulkier than with carcinoma and extend beneath the renal hilum.

Many, but not all, mesenchymal tumors previously diagnosed as leiomyomas, leiomyoblastomas, leiomyosarcomas, and other lesions are placed in this category. Up to 30% are malignant, and the risk increases with extragastric location, larger diameter ( 5 cm), and extension into adjacent organs.
