Neurosarcoidosis With Multi-Organ Involvement: A Case Report and Literature Review.

Sarcoidosis is a multisystemic disease that, in rare cases, can involve the central nervous system (CNS). We present a case of sarcoidosis with intracranial and multi-organ involvement. The patient presented with a one-month history of headaches. Imaging revealed leptomeningeal nodular enhancement (LNE), and a PET/CT scan of the chest and abdomen showed bilateral hilar, retroperitoneal, and inguinal lymphadenopathy. The diagnosis of sarcoidosis was confirmed by an ultrasound-guided inguinal lymph node biopsy. The patient was started on a combination of corticosteroids and immunosuppressive drugs, with a gradual improvement in symptoms and radiological findings over several months.

Postmortem fetal magnetic resonance imaging: where do we stand?

Postmortem fetal magnetic resonance imaging (PMFMRI) is increasingly used thanks to its good overall concordance with histology paralleling the rising incidence of parental refusal of autopsy. The technique could become a routine clinical examination but it needs to be standardized and conducted by trained radiologists. Such radiologists should be aware of not only the (congenital and acquired) anomalies that can involve the fetus, but also of the "physiological" postmortem changes. In this article, we intend to focus on the contribution of PMFMRI based on the existing literature and on our own experience, as we presently perform the technique routinely in our clinical practice. KEY POINTS: • Concordance rates between PMFMRI and autopsy are high for detecting fetal pathologies. • PMFMRI is more acceptable for parents than traditional autopsy. • PMFMRI is becoming widely used as a part of the postmortem investigations. • A dedicated radiologist needs to learn to interpret correctly a PMFMRI. • PMFMRI can be easily realized in daily clinical practice.

Kirschner wire migration causing spinal cord injury one year after internal fixation of a clavicle fracture.

K-wire migration after internal fixation of the clavicle has rarely been reported to cause spinal cord injuries. A 30-year-old man presented with progressive paraparesis, hypaesthesia under a Th4 level and electric pain in the neck and arms. CT of the spine revealed a migrated K-wire from a one-year-old clavicle osteosynthesis, penetrating the spinal canal through the Th2 nerve root foramen, and perforating the spinal cord with a transversal trajectory. Surgical removal of the K-wire was performed after exposing both ends. Laminectomy allowed visual control of the entry point and correction of cerebrospinal fluid leakage. The pain disappeared and the patient recovered a normal gait after 6 weeks. The use of two incisions is advocated in such cases: one lateral to allow wire removal, and one medial for dural repair and early intradural bleeding control. Regular follow ups, K-wire removal after fracture healing as well as bending the wire end in a walking stick shape should minimise the risk of migration.

Percutaneous treatment of iatrogenic iliocaval fistula related to endograft placement for abdominal aortic aneurysm.

The authors report a case of iatrogenic dissection occurring during endovascular treatment of an abdominal aortic aneurysm. The dissection was related to catheterization maneuvers that led to the development of a symptomatic arteriovenous fistula, which was successfully closed by coil embolization.
