Case characteristics

Spontaneous left arm weakness, objective vertigo, obesity.

Clinical diagnosis

Left arm downward drift associated with local joint pain.

Differential diagnosis

Acute vasculopathy; neuropathies; joint affections.

Laboratory diagnosis

Unremarkable laboratory examination.

Imaging diagnosis

A head NCCT revealed the presence of a left-sided hypodense peri-callosal curvilinear lesion; a CT Angiography ruled out vascular obstructions, while the thoracic scan showed two posterior extradural hypodense lesions at T1-T2. The MRI did not show diffusivity alterations: the curvilinear peri-callosal lesion appeared hyperintense in T1-W and hypointense at fat suppression sequences, without contrast enhancement, thus confirming the lipoma.


Rest and painkillers.

Term explanation

Envelopathies: defects of proteins making up the nuclear envelope.

Experiences and lessons

A particular obesity pattern associated with cerebral-spinal lipomas may be related to the same gene defect in patients affected by the Emery-Dreifuss muscular dystrophy X-linked variant. In our case, lipomas may be considered incidental findings, whereas the patient’s symptoms could be related to an initial painful contracture, which is a typical hallmark of the disease.
