Some causes of spastic paraplegia are treatable and many are not. Diagnostic work-up to determine the etiology can be costly and invasive. Here we report the case of a man with slowly progressive spastic paraparesis. Using a multigene next-generation sequencing (NGS) panel, we identified a novel variant in the consensus splice site of the SPAST gene (exon 13, c.1536G>A, heterozygous), affecting codon 512 of the SPAST mRNA. The observed variant segregated with the disease in four tested family members. In this case, genetic confirmation obviated the need for additional testing such as MRI and lumbar puncture and helped the patient and his family understand his condition and prognosis. We conclude with a brief discussion of the SPG4/SPAST gene and the role of multigene panels in the diagnosis and management of hereditary spastic paraplegia.

Magnetic resonance imaging and pathological findings of aortoiliac thromboembolism with a thoracic aortic mural thrombus in a Japanese Black calf.

A 24-day-old female Japanese Black calf presented a sudden paraplegia after a history of watery diarrhea. Antemortem magnetic resonance imaging confirmed the suspicion of thrombotic component in the abdominal aorta, without any spinal cord abnormality at the lumbar region. On necropsy, a massive thrombus occupied the lumen from the distal abdominal aorta to the bifurcation of the external iliac arteries.

Just 40 years ago, Europe was divided into the Eastern communist bloc, which included the Czechoslovak Socialist Republic (ČSSR) and was dominated by the now historical Soviet Union, and the Western bloc comprising democracies such as Austria. The Iron Curtain, a heavily guarded and deadly border zone, separated the two blocs and constrained, in prison style, the populations of the Eastern bloc. The present neuropathological article relates the sad fate of František Faktor, a 33 years-old Czech who was shot by ČSSR border guards when attempting to flee to Austria at the border between and .

Among these, spastic paraplegia type 11 (SPG11) represents a complex form of HSP caused by deleterious variants in the SPG11 gene, which encodes the spatacsin protein. Previous studies have described several potential roles for spatacsin, including its involvement in lysosome and autophagy mechanisms, neuronal and neurites development or mitochondria function.

Background Context: On radiopathological examination of spinal tuberculosis (TB), two predominant forms are known: dry and wet types. Wet TB, as the name suggests, has abscess formation as its predominant presenting feature and is the exudative form; dry TB includes caseation and sequestration with minimal exudate. Dry TB often exhibits poorer recovery patterns than the wet counterparts, which can be possibly ascribed to vasculitis, ischemia, or tubercular myelitis, rather than isolated mechanical compression.
