RESUMO
Rapid ossification due to a subperiosteal hematoma in extremities has occasionally been documented in patients with neurofibromatosis type 1, but it has not been reported in the maxillofacial region. The authors present the first case of a subperiosteal hematoma in the forehead. A 36-year-old man presented with a rapidly swelling firm, fixed, 8×10 cm forehead mass. It became evident shortly after a fine-needle aspiration biopsy. Computed tomography imaging 2 months after the biopsy showed a hematoma that was encapsulated by a surrounding layer of ossification. Magnetic resonance imaging displayed a fluid-fluid level under the ossified area. These characteristic images led us to diagnose this rare lesion as a subperiosteal hematoma with ossification. Rapid ossification is a characteristic imaging finding of subperiosteal hematoma, which makes definitive diagnosis easy. It becomes imperative to underscore the potential risks of fine-needle aspiration in proximity to the periosteum in patients with neurofibromatosis type 1.
RESUMO
ABSTRACT: Klippel-Trenaunay syndrome (KTS) is characterized by port-wine stains, mixed vascular malformations, and soft tissue and bone hypertrophy. Klippel-Trenaunay syndrome is occasionally complicated by chyluria, for which there is no effective treatment currently. We report a case of KTS complicated by intractable chyluria and hematuria due to a lymphatic-ureteral fistula. The patient was successfully treated with multiple lymphaticovenular anastomoses (LVAs).A 66-year-old woman with an enlarged left lower extremity since childhood was diagnosed with KTS. At 60 years of age, she developed chyluria (urine albumin, 2224 µg/mL) and hematuria. Lymphoscintigraphy showed a lymphatic-ureteral fistula near the ureterovesical junction. Conservative treatment was ineffective. She also developed left lower extremity lymphedema, which gradually worsened. Leg cellulitis and purulent pericarditis developed because of hypoalbuminemia (minimum serum albumin level, 1.3 g/dL).We performed 14 LVAs in 2 surgeries to reduce lymphatic fluid flow through the lymphatic-ureteral fistula. The chyluria and hematuria resolved soon after the second operation, and the urine albumin level decreased (3 µg/mL). After 28 months, she had no chyluria or hematuria recurrence and her serum albumin level improved (3.9 g/dL). Multiple LVAs can definitively treat chyluria caused by a lymphatic-ureteral fistula in patients with KTS.

INTRODUCTION: Reports of retroperitoneal infection related to a sacral pressure injury (PI) are rare, and none of the reports described the direct spread of infection through the sacrum to the retroperitoneum. The authors present, to their knowledge, the first report of a severely infected PI that showed full-thickness sacral destruction and direct retroperitoneal penetration. CASE REPORT: A 63-year-old female was referred for management of a stage 4 sacral PI complicated by a retroperitoneal abscess. The patient's comorbidities were diabetes mellitus and pemphigus foliaceus with steroid therapy-induced immunosuppression. Upon admission, the patient presented with a sacral PI producing copious purulent discharge that measured 5 cm × 3 cm. Magnetic resonance imaging revealed full-thickness sacral bone destruction and a massive retroperitoneal abscess, suggesting the sacral PI directly penetrated to the retroperitoneal space. Antibiotics were administered, and surgical debridement and sequestrectomy were performed. Negative pressure wound therapy (NPWT) with continuous saline irrigation was initiated. The patient's mesorectum was exposed within the retroperitoneal space. Therefore, a nonadhesive wound dressing was applied before placing the irrigation tube to avoid perforating the rectum. Because the patient had fragile skin secondary to long-standing pemphigus foliaceus and steroid treatment, a liquid skin protectant and hydrocolloid wound dressing were applied. The infection was successfully controlled with NPWT with saline irrigation. The patient experienced no rectal injury or skin rupture, and surgical closure was performed after 75 days. Although partial wound dehiscence occurred because of the poor condition of the skin, the resultant open wound was managed conservatively. The patient showed no retroperitoneal abscess recurrence 6 months later. CONCLUSIONS: A rare case of an intractable sacral PI complicated by retroperitoneal abscess was successfully managed in an immunocompromised patient. Notably, NPWT with saline irrigation was useful in controlling the patient's severe retroperitoneal infection.
