Renal angiomyolipoma is a benign tumour of the kidney which is often mistaken for a renal cell carcinoma resulting in an unnecessary nephrectomy. It can be diagnosed preoperatively and managed conservatively without surgery. Large symptomatic renal angiomyolipomas can often be treated by renal-sparing surgery. We report a case of a large renal angiomyolipoma diagnosed preoperatively and excised completely with preservation of the kidney.
A 30 year old Malay male developed bilateral choroiditis followed by vitiligo, poliosis and canities. CT scan showed nodular thickening of the optic nerves. Characteristic abnormalities were seen in visual and brainstem auditory evoked potentials and fluorescein angiography. These findings were in keeping with the diagnosis of Vogt-Koyanagi-Harada syndrome. Treatment with dexamethasone resulted in complete recovery of vision and partial improvement in skin and hair lesions.
Sexually deviant behaviour is a fairly common phenomenon but because it is socially embarassing, a few cases come forward for consultation and treatment on a voluntary basis. Most cases are referred by the law courts. Two such cases, one of exhibitionism and the other offetishism, were referred to the University Hospital, Kuala Lumpur in 1982. Their development histories were elaborated. A third case of sexual sadism came voluntarily for help out defaulted after the initial session. A review on the current western concepts on sexual deviation is included in the text. It is concluded that although it is generally thought that neurological conditions give rise to deviant sexual behaviour, this assumption should not be arrived at hastily, as many cases of organic mental disorders do not exhibit deviant sexual
behaviour.
Enteroenteric intussusception is a condition in which the full-thickness bowel wall becomes telescoped into the lumen of distal bowel. Intussusception in adult occurs infrequently and varies from childhood intussusception, particularly in its presentation, aetiology and treatment. Duodenoduodenal intussusception is rare because the duodenum is fixed in the retroperitoneal position. It usually occurs secondary to tumour, lipoma, Brunner's gland hamartomatous polyp or adenoma. The diagnosis in adults is usually made at laparotomy, where presentation is with intestinal obstruction. In non-emergency presentation, it may be difficult to arrive at an accurate diagnosis as symptoms may be vague, self-limiting intermittent abdominal pain. Clinical examinations and investigations may not be conclusive and another working diagnosis such as irritable bowel syndrome would be made. We describe a case where a patient initially presented with symptoms mimicking pancreatitis but his symptoms persisted over the course of 2 weeks. When a laparotomy was performed, duodenoduodenal intussusception was discovered and confirmed with histopathology. In this case, a discernible leading point could not be identified.
Adult onset still's disease usually presents with high grade intermittent fever, polyarthritis, salmon pink evanescent rash and hepatosplenomegaly. Pulmonary involvement in the form of pneumonitis, as a presenting feature is very rare. We report a case of a young lady who presented with fever, cough and respiratory distress. Chest X-ray revealed patchy infiltration in left upper lung zone. She was subsequently diagnosed as Adult onset Still's disease. There was no improvement in clinical condition despite five days of antibiotics. On trans-bronchial lung biopsy (TBLB) proved she had interstitial pneumonitis and responded dramatically to steroid treatment.
A case report of adenoid cystic carcinoma of the trachea is presented. A high index of suspicion is required to make the diagnosis of tracheal tumours early since the patients tend to have normal chest radiographs which on closer examination may show an abnormality of the tracheal column. Adenoid cystic carcinoma is the most common malignant tumour of the trachea. Locoregional control of this disease is achieved by a combined modality therapy of surgery and postoperative radiotherapy. Despite this, it still has a prolonged clinical course and the tendency for delayed onset of distant metastases.
Mesenteric venous thrombosis has been described to occur in cases where there has been no apparent cause. The diagnosis is usually delayed because the signs and symptoms are non-specific. A case of primary mesenteric venous thrombosis is reported below. Its presentation and pathology are discussed. Treatment is surgery with resection of gangrenous bowel and primary anastomosis. Post-operative anticoagulation is advocated.
Melorheostosis is a rare osteosclerotic bone dysplasia. It is usually characterized by dull and aching pain, reduced joint motion and contractures. Classic radiograph findings are of undulating cortical hyperostosis along the length of the bone, simulating a "dripping candlewax appearance". We report two cases of melorheostosis of the ulna bone, diagnosed 6 years apart in two different females in their early 20s. Both the patients presented with the characteristic features of dull and aching pain in the forearm and were treated conservatively. However, we misdiagnosed the first case as bone malignancy and subjected the patient to a biopsy. For the second case, with hindsight we made the correct diagnosis based only on the classic clinical history and radiographs. We believe that the discussion of a misdiagnosed case of melorheostosis with salient findings may be important for clinicians and orthopedicians in day-to-day clinical practice.
