1/22. pituitary apoplexy following metastasis of bronchogenic adenocarcinoma to a prolactinoma.A 42-year-old house wife presented with worsening headaches over 6 months in the absence of visual symptoms or symptoms suggestive of focal neurology. She was a life-long smoker. Systems review was unremarkable apart from secondary amenorrhoea and galactorrhoea of 6 months duration. Her serum prolactin was found to be 620 mU/l (60-400), FT4 12.6 nmol/l (9.8-23.1), TSH 1.38 mU/l (0.35-5.5), oestradiol < 73 pmol/l, LH and FSH of 4.4 and 12.6 mIU/l, respectively. She was on bromocriptine. A presumptive diagnosis of pneumonia, based on pyrexia and CXR findings, was made and she was started on IV antibiotics. Two days later she developed meningism and deterioration of conscious level. (Lumbar puncture results: no organisms, 312 neutrophils and 164 lymphocytes). CT scan revealed a 2.5-cm pituitary adenoma, with suprasellar extension. A repeat hormonal profile revealed FSH 1.4, LH < 0.3 mU/l, oestradiol < 73 pmol/l, prolactin 488 mU/l (60-400), and low random cortisol at 29 nmol/l. T1-weighted MRI revealed a large pituitary mass with evidence of haemorrhage. The patient subsequently underwent a transsphenoidal exploration with resection of the pituitary lesion. Whilst awaiting the histopathology results, CT of chest revealed a 1. 5-cm diameter rounded well defined density in the right lower lobe associated with hilar, pre- and right para-tracheal lymphadenopathy. The histopathology of the pituitary lesion, obtained piecemeal, revealed fragments of fibrous tissue infiltrated by sheets of acidophilic prolactin-positive cells, in keeping with a prolactinoma. In addition, other fragments with blood clot included highly atypical epithelial cells with mitotic figures. These were negative for prolactin but showed HMFG-and CEA-positivity, excluding them from a pituitary lineage. Transbronchial biopsy revealed moderately differentiated adenocarcinoma, with evidence of lymphatic spread. The overall conclusion was of bronchogenic adenocarcinoma, metastasizing to a prolactinoma and complicated by apoplexy.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/22. Massive intrathoracic haemorrhage after CT-guided lung biopsy.CT-guided lung biopsy is now widely performed for tumorous lesions in the lung, and both its usefulness in this context and the associated complications have been well described in the literature. Although severe complications are rare, we describe a case in which massive intrathoracic haemorrhage developed after lung biopsy and necessitated emergency operation for control. Intraoperative findings suggested that the source of the haemorrhage was a fibrous, cord-like substance present at the site of adhesion associated with old tuberculosis. We attributed this haemorrhage to a pneumothorax, which developed after lung biopsy and caused the new vessels penetrating the centre of the fibrous, cord-like substance to stretch and rupture. Numerous cases have been reported of spontaneous haemopneumothorax precipitated by spontaneous pneumothorax and resulting from the rupture of such vessels.- - - - - - - - - - ranking = 7keywords = haemorrhage (Clic here for more details about this article) |
3/22. Primary cardiac leiomyosarcoma with pulmonary metastases: a diagnostic problem.A case of primary cardiac leiomyosarcoma is reported. Tumour growth into the right ventricular cavity led to multiple pulmonary metastases with haemorrhage. Failure of diagnostic procedures including cardiac catheterisation, angiography and thoracotomy is noted. The incidence and presentation of primary malignant cardiac tumours is briefly discussed.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
4/22. Cutaneous metastases from Ewing's sarcoma: report of two cases.Ewing's sarcoma is a malignant osseous neoplasm that affects mostly children and young adult males. Clinically, the neoplasm presents with oedema, swelling, and pain of the involved area. Histopathologically, Ewing's sarcoma consists of solid sheets of small round cells, with vesicular nuclei and scant cytoplasm, arranged in irregular masses separated by strands of fibrous tissue, with areas of necrosis en masse intermingled with intratumoural haemorrhage. Ewing's sarcoma is an extremely aggressive neoplasm and metastases to sites such as lung, pleura, other bones, central nervous system, liver, and regional lymph nodes frequently develop in early stages of the disease. Surprisingly, despite the highly aggressive biological behaviour of this neoplasm, cutaneous metastases from Ewing's sarcoma are very uncommon. We report two patients with Ewing's sarcoma of the bone who developed cutaneous metastases. As in other internal malignancies, the onset of cutaneous metastases in patients with Ewing's sarcoma indicates a poor prognosis.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
5/22. Negative pressure pulmonary oedema in the medical intensive care unit.OBJECTIVE: Negative pressure pulmonary oedema (NPPE) occurring in the medical intensive care unit (MICU) is an uncommon, probably under-diagnosed, but life-threatening condition. DESIGN: Retrospective data collection. SETTING: Medical intensive care unit in a 1,500-bedded tertiary care hospital. patients AND PARTICIPANTS: Five patients were diagnosed between January 1998 and January 2002. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: Five patients were diagnosed to have NPPE from different aetiologies. These were acute epiglottitis, post-stenting of right bronchus intermedius stenosis, strangulation, compression from a goitre and one patient developed diffuse alveolar haemorrhage after biting the endotracheal tube during recovery from anaesthesia. All patients responded rapidly to supplemental oxygen, positive pressure ventilation and correction of underlying aetiologies. Pulmonary oedema resolved rapidly. CONCLUSIONS: There is a large spectrum of aetiologies causing NPPE in the medical intensive care unit.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
6/22. acute lung injury as a possible adverse drug reaction related to gefitinib.Gefitinib is a potent drug used in the treatment of nonsmall-cell lung cancer (NSCLC). Gefitinib acts by inhibition of the epidermal growth factor receptor tyrosine kinase. Clinical trials have confirmed the efficacy of gefitinib for NSCLC. Adverse drug reactions, although frequent, are mild, and include acne-like skin rash and diarrhoea. The present study describes the case of a 56-yr-old male with NSCLC who, 4 weeks after treatment with gefitinib, suffered from a severe alveolar haemorrhage diagnosed by bronchoalveolar lavage. This is the first case report of an acute life-threatening lung injury in a patient with nonsmall-cell lung cancer who had been given gefitinib.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
7/22. Massive intestinal haemorrhage due to a solitary jejunal metastasis of a primary bronchogenic tumour.A case is presented of a 72-year old male patient presenting with a massive intestinal blood loss due to a solitary jejunal metastasis of a poorly differentiated adenocarcinoma of the right lung resected two years earlier. After diagnostic workup and stabilization a small bowel resection with end to end anastomosis was performed. Patient is alive and well 5 months after operation. Solitary bleeding intestinal metastasis of a primary bronchogenic tumour are extremely rare but should be included in the differential diagnosis of gastrointestinal blood loss in a patient with a known bronchogenic tumour. Resection with end to end anastomosis is the treatment of choice.- - - - - - - - - - ranking = 4keywords = haemorrhage (Clic here for more details about this article) |
8/22. Fatal myocardial infarction after lung resection in a patient with prophylactic preoperative coronary stenting.In this report we present the case of a 77-yr-old man who underwent resection of the upper lobe of the left lung for a carcinoma, six weeks after percutaneous transluminal coronary angioplasty (PTCA) with stenting of the left anterior descending (LAD) and circumflex coronary arteries. Antiplatelet therapy with clopidogrel was interrupted two weeks before surgery to allow for epidural catheter placement and to minimize haemorrhage. The surgical procedure was uneventful. In the immediate postoperative period, however, the patient suffered severe myocardial ischaemia. Emergency coronary angiography showed complete thrombotic occlusion of the LAD stent. In spite of successful recanalization, reinfarction occurred and the patient died in cardiogenic shock. Prophylactic preoperative coronary stenting may put the patient at risk of stent thrombosis if surgery cannot be postponed for three months. In such cases, other strategies such as perioperative beta-blockade for preoperative cardiac management should be considered.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
9/22. Haemorrhagic shock from the spontaneous rupture of an adrenal cortical carcinoma. A case report.Adrenal cortical carcinoma is a rare endocrine neoplasm which can be either functioning or non-functioning. Usually, patients refer to the doctor because of abdominal pain or symptoms associated with the mass effect. We present an unusual case of a patient with adrenal cortical carcinoma who was immediately operated due to massive retroperitoneal haemorrhage following the spontaneous rupture of the tumour. Adrenal cortical carcinoma should enter in differential diagnosis of retroperitoneal haemorrhage. Surgeons should be familiar with this clinical entity and attempt complete resection if possible.- - - - - - - - - - ranking = 2keywords = haemorrhage (Clic here for more details about this article) |
10/22. Pulmonary haemangiosarcoma with main pulmonary artery thrombosis imitating subacute pulmonary embolism with infarction.We report a patient with subacute pulmonary hypertension caused by unilateral massive pulmonary artery thrombosis due to a pulmonary haemangiosarcoma of the lower lobe with pulmonary arterial and bronchial invasion. The patient was misdiagnosed as having subacute pulmonary embolism and underwent thrombolytic therapy complicated by severe pulmonary haemorrhage. The imaging features of pulmonary artery thrombosis with underlying malignancy and their differential diagnosis are discussed.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
