Gadolinium leakage into subarachnoid space and cystic metastases.
Subarachnoid space (SAS) and cystic metastatic lesions of brain parenchyma appear hypointense on fluid-attenuated inversion-recovery (FLAIR) and T1-weighted magnetic resonance imaging (MRI) unless there is a hemorrhage or elevated protein content. Otherwise, delayed enhancement and accumulation of contrast media in SAS or cyst of metastases should be considered. We present hyperintense SAS and ...
متن کاملGadolinium-DTPA in MR imaging of glioblastomas and intracranial metastases.
In 14 patients with the diagnosis of glioblastoma (n = 7) or intracranial metastases (n = 7), magnetic resonance (MR) imaging was performed using a variety of spin-echo (SE) pulse sequences before and after intravenous injection of 0.1 mmol gadolinium-DTPA (Gd-DTPA) per kilogram of body weight. In 10 patients, tumor tissue could not be adequately differentiated from perifocal edema on unenhance...
متن کاملCystic temporofacial rhabdomyosarcoma with subarachnoid communication.
Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma of childhood. The neoplasm probably originates from pluripotential mesenchyme, and may occur anywhere in the body. Thirty to 40% arise in the head and neck. Imaging studies typically show a homogeneous soft-tissue mass, often with poorly defined margins and permeative bone destruction (1-5). We report an unusual case of embryonal RMS...
متن کاملPharmacokinetics and toxicology of immunotoxins administered into the subarachnoid space in nonhuman primates and rodents.
Immunotoxins have been suggested as possible therapeutic agents in patients with leptomeningeal carcinomatosis. The pharmacokinetics, stability, and toxicity of immunotoxins injected into the i.t. space were examined in rats and rhesus monkeys. Monoclonal antibodies specific for the human (454A12 and J1) and rat (OX26) transferrin receptors were coupled to recombinant ricin A chain. In monkeys,...
متن کاملIntra-operative epidural catheter migration into subarachnoid space leading to massive subarachnoid injection of morphine--a case report.
Epidural catheter (EC) migration is well documented entity in literature. However, most of these reports are consistent with introduction of Tuohy needle, either partially or completely, into intravascular, subdural and subarachnoid spaces prior to the placement of catheter. We report an intra-operative delayed migration of epidural catheter into subarachnoid space after apparently normal needl...
