| Advanced pulmonary disease is an unusual consequence of the intravenous injection of oral medications, usually developing over a period of several years. A number of patients with this condition have undergone lung transplantation for respiratory failure. However, a history of drug abuse is often considered to be a contraindication to transplantation in the context of limited donor resources. A patient with pulmonary talc granulomatosis secondary to intravenous methylphenidate injection who underwent successful lung transplantation and subsequently presented with recurrence of the underlying disease in the transplanted lung 18 months after transplantation is reported.

2/376. Expanded polytetrafluoroethylene threads for lip augmentation induce foreign body granulomatous reaction. Especially in cases of facial aesthetic surgery, the demands of the patients are high. The formation of a visible and painful nodule will cause not only discomfort but also dissatisfaction. When alloplastic materials are used for facial and lip augmentation, the possibility of migration, allergic reaction, and formation of a foreign body granuloma is always present. Although e-PTFE is the most bioinert alloplastic material available, the authors could show the formation of a foreign body granuloma. When using e-PTFE threads for facial augmentation, the surgeon should keep in mind and inform the patients that the threads can induce a foreign body granulomatous reaction. ( info) |
3/376. Imaging features of simultaneous occurrence of renal and pancreatic foreign body granuloma due to chronically retained gauze: a case report. Herein we are reporting a case of simultaneous occurrence of renal and pancreatic foreign body granuloma due to retained gauze. The different imaging features of the two lesions make correct preoperative diagnosis difficult. Foreign body granulomas due to retained surgical gauze or sponges should be considered in patients who have previous histories of operations and who also have a mass in the surgical bed. Simultaneous occurrence of foreign body granuloma away from primary surgical field is also possible. ( info) |
4/376. Severe migratory granulomatous reactions to silicone gel in 3 patients. In humans implanted with silicone gel breast prostheses, a mild foreign body response results in the formation of a collagenous capsule around the prosthesis. Although many such patients may show evidence of a microscopic granulomatous foreign body reaction upon examination of capsular material at explantation of a prosthesis, it is unusual to have large, palpable granulomas, even in the presence of rupture or leakage. Rare patients have had severe local inflammation and complications resulting from silicone migration to the axilla, arm, or abdominal wall. We describe 3 patients who had deforming granulomas after implant rupture, along with other consequences of silicone gel migrating down the upper extremity. Silicone gel, once it leaves the implant, is not biologically inert and in some persons can elicit profound pathologic responses. ( info) |
| OBJECTIVE AND IMPORTANCE: Intracranial foreign body granulomas are rare. We describe a case of an intracranial foreign body granuloma found in a 17-year-old female patient 9 years after she underwent a craniotomy for a tumor of unknown type. Postoperative imaging of patients who have undergone neurosurgical procedures can often reveal enhancing masses, and foreign body granuloma should be included in the differential diagnosis. CLINICAL PRESENTATION: The patient presented with a history of developmental delay, panhypopituitarism, and chronic headache. Admission resulted from an acute increase in the severity of her headache. INTERVENTION: Imaging studies, including computed tomography and magnetic resonance imaging, demonstrated a 1.5 x 2 cm round, enhancing anterior interhemispheric mass, appearing to arise from the falx and causing mild mass effect. A nonenhancing cystic mass was also noted in the suprasellar region but was without mass effect. The patient underwent a craniotomy and removal of the anterior mass without complication, and her headache resolved. A pathological examination of the specimen confirmed the diagnosis of foreign body granuloma. CONCLUSION: Although rare, foreign body granuloma should be included in the differential diagnosis of previously operated intracranial masses. The importance of accurate historical information and guidelines that may assist in diagnosis are discussed. ( info) |
6/376. Disintegration of porous polyethylene prostheses. A Plastipore (porous polyethylene) Total ossicular replacement Prosthesis gave an excellent initial hearing result which was maintained for 14 years. hearing then began to deteriorate and revision surgery showed disintegration of the prosthesis and a defect in the stapes footplate. Histological examination confirmed previous findings in porous polyethylene with multinucleated foreign body giant cells and breakdown of the material. ( info) |
7/376. Postoperative alveolar hydatid disease with cutaneous-subcutaneous involvement. The first Japanese case of alveolar hydatid disease with cutaneous-subcutaneous lesions is reported. The patient, a 58-year-old man who developed an indurated subcutaneous tumor on the right side of the abdomen, had had partial hepatectomy of the right lobe for echinococcosis thirteen years earlier. Clinically, the tumor was adherent with a fistulosis communication to deeper structures. Histopathologically, multiple PAS-positive cuticular layers with foreign body granulomas and fibrosis were observed between the dermis and subcutaneous fatty tissue. Surgical excision of the swelling provided the patient with temporary relief. To our knowledge, only eight cases of subcutaneous alveolar hydatid disease have been reported throughout the world. Ours, the ninth case, highlights the importance and difficulty of treating of alveolar hydatid disease. ( info) |
8/376. cellulose granulomatosis of the lungs. Chest radiographs and high-resolution chest CT scans were performed in a 30-year-old man with a history of intravenous drug abuse and diffuse micronodular infiltrates. Transbronchial biopsy gave a diagnosis of cellulose granulomatosis of the lung. cellulose granulomatosis should be considered in the differential diagnosis of pulmonary interstitial disease, especially in the setting of intravenous drug abuse.

9/376. aluminum silicate-containing psammoma bodies in a cervicovaginal smear (Pap): cytological, ultrastructural, and radiographic microprobe studies. Psammoma body is a rare finding in a cervicovaginal smear and can be associated with either benign or malignant diseases. Here we report a case to illustrate the association of psammoma bodies with benign granulomatous reactions to a foreign material (aluminum silicate). ( info) |
10/376. Cotton gauze foreign body granuloma following microvascular decompression. We describe a case of a cotton gauze foreign-body granuloma developing 2 months after microvascular decompression for trigeminal neuralgia and hemifacial spasm. This complication has not been previously described. Moreover, the patient's initial clinical and radiological findings were suggestive of an acoustic neuroma or meningioma at the time. ( info) |
