RESUMO
Post-traumatic fibro-osseous lesions (PTFOL) are a rare and benign tumor that typically affects the ribs and is probably caused by an excessive post-traumatic reactive process. PTFOL primarily affects the sixth, seventh, and eighth ribs. Here, we report a case of a PTFOL with an unusual location and expansion that simulated a malignant chest tumor. A 28-year-old male patient with a history of minor chest trauma presented with pain. Chest radiography revealed a large, well-defined lesion on the left fourth rib, and computed tomography (CT) of the chest revealed a lytic lesion-type IC on the posterior and middle arches of the left fourth rib with a cartilaginous matrix and discontinued periosteal reaction without soft tissue mass extension. Additionally, magnetic resonance imaging of the chest revealed an ovoid, expansive mass with cystic lobules and lobulated contours extending almost over the entire left fourth rib, measuring 134×47 mm in size. This mass has a low signal on T1-weighted images and a heterogeneous intermediate signal on T2-weighted images, with intense enhancement after gadolinium injection suggestive of a malignant chest tumor. A CT-guided bone biopsy confirmed the presence of an intramedullary lesion consisting of fibrous connective tissue with fusiform fibroblastic cells without atypical signs. The lesion was delimited by bone trabeculae with nibbled edges, indicating exaggerated osteoclastic activity compatible with a diagnosis of PTFOL. The patient was treated with simple analgesics, and chest pain was relieved, with an unchanged volume of the lesion at 1 year of follow-up.
RESUMO
Celiac disease (CD) is an autoimmune enteropathy resulting from intolerance of an individual genetically predisposed to gluten. It has a large clinical polymorphism ranging from a classic digestive clinical presentation due to the malabsorption syndrome to extra-intestinal symptoms. Among the hematologic abnormalities, venous thromboembolic disease (VTE) has been reported, and they are most often located in the abdomen or lower limbs, but the cerebral localization was exceptionally described. We report a case of CD revealed by cerebral thrombophlebitis. A 44-year-old patient with no medical history and no drug intake, presented with hemiplegia followed by a status epilepticus in a context of apyrexia, initially hospitalized in intensive care. Magnetic imaging resonance displayed a cerebral venous thrombosis of the sigmoid sinus requiring anticoagulant treatment, then transferred to our department for the etiological investigation. On questioning, the patient reported chronic diarrhea and weight loss with no other associated symptoms. The examination revealed an underweight patient with pale conjunctiva, improvement of her deficit symptoms, and no other abnormalities. Laboratory tests noted biological signs of malabsorption. The thrombophilia assessment revealed a protein C deficiency with a slight increase in anticardiolipin antibodies and anti-Beta 2 glycoprotein 1 antibodies. Immunological tests noted positives anti-transglutaminase and IgA anti-endomysium antibodies. Duodenal biopsy demonstrated villous atrophy. After ruling out the other causes of VTE, the diagnosis of cerebral venous thrombosis secondary to CD was retained. Early diagnosis and treatment of CD improves the quality-of-life for patients and may spare them various long-term or even fatal complications.
