Spontaneous hemothorax is a rare and potentially lethal neurofibromatosis' complication. Several pathological mechanisms may explain the associated vasculopathy: a) direct vascular invasion from adjacent tumors such as Shwannoma, neurofibroma or neurofibrosarcoma; b) vascular dysplasia with stenotic or aneurysm formation. Other mechanisms involved may include pleuropulmonar pathologies (necrotizing infections, pulmonary embolism, endometriosis, neoplasms) and blood dyscrasias. The authors describe a case of a 33 years old female, who went to the ER Service complaining with right persistent hemithoracic pain, extending to the ipsilateral shoulder and shoulder blade, without aggravation or relieving factors, since the last 8 days.

Following a brief introduction covering the clinical signs and symptoms of pulmonary hypertension (PH), its most recent classification into six groups, and the computed tomography (CT) features common to all forms of PH, this paper illustrates the typical patterns that can be found on chest radiography and CT in rare causes of PH. We present and compare with the existing literature our personal series of cases of rare forms of PH, found in the following diseases: veno-occlusive disease, pulmonary capillary haemangiomatosis, non-thrombotic pulmonary embolism (tumour embolism and carcinomatous lymphangitis, talcosis, hydatid disease), pulmonary artery sarcoma, neurofibromatosis, sarcoidosis, and Langerhans cell histiocytosis. Rare forms of PH show low incidence and prevalence, and are, therefore, poorly recognised. Their diagnosis is a challenge for clinicians, pathologists, and radiologists, and any additional knowledge about the CT findings may help the diagnosis in the case of patients affected by PH of unknown origin.

Neurofibromatosis type 1 (NF1), also known as Von Recklinghausen's disease is an autosomal dominant genetic disorder. It is the most common of phacomatoses. Pulmonary complications have been rarely described in the literature. Vascular complications have been reported in 3.6% of patients. We here report the case of a 38-year old female patient, followed-up for neurofibromatosis type 1, admitted to the Emergency Department with hemorrhagic shock. Clinical examination showed several coffee-with-milk colored spots, many plexiform neurofibromas, left-sided pleural effusion syndrome. Pleural puncture objectified coagulable haemorrhagic fluid. The patient received transfusion and emergency chest drainage. Patient's assessment was completed by angioscanner which showed no pulmonary embolism or other associated lesions. Spontaneous hemothorax is a rare and severe complication of neurofibromatosis. It is probably due to vascular injury caused by this disease.

BACKGROUND Von Recklinghausen's disease, also known as Type 1 neurofibromatosis (NF1), is a genetic disorder characterized by skin tumors, neurofibromas of multiple organs and vascular abnormalities. Spontaneous thoracic hemorrhage is a rare but potentially fatal consequence of this disorder. After a review of the literature over the last 10 years and on the basis of a case study, the aim of this study was to report the challenges of management of this pathology. CASE REPORT We report a rare case of a 45-years-old male with a medical history of neurofibromatosis who complained of a 3-day history of progressive dyspnea. At his admission to the Emergency Department, the patient was hemodynamically stable. A chest computed tomography (CT) scan showed a large left hemothorax with mediastinal shift to the right without active bleeding. A chest tube was introduced, and conservative treatment was followed. Another CT scan performed 2 days later revealed a middle lobar pulmonary embolism on the opposite side. A full treatment of anticoagulation was administered, and the patient was released after 8 days of hospitalization. Three weeks later, a new chest CT scan indicated the absence of vascular aneurysm or source for hemothorax. CONCLUSIONS Our systematic literature review found 15 articles which were described as early as 2005. To our knowledge, endovascular treatment produces the best immediate successful result (100%) and may be used in adjunction with video-assisted thorax surgery (VATS) or thoracic drainage to optimize outcomes. In the present case, conservative treatment showed a good result despite anticoagulation for pulmonary embolism. The endovascular approach seems to be the most promising, but treatment needs to be tailored to each individual patient.
