Rumpel-Leede phenomenon in a hypertensive patient due to mechanical trauma: a case report

BACKGROUND In this report, we present an interesting case of a patient with Rumpel-Leede phenomenon, a rare occurrence that can result in significant delays in medical treatment. This phenomenon is characterized by the presence of a petechial rash that results from acute dermal capillary rupture. In our patient, it occurred secondary to raised pressure in the dermal vessels caused by repeated i...

Rumpel-Leede phenomenon associated with noninvasive blood pressure monitoring -A case report-

We report a case of Rumpel-Leede (RL) phenomenon, - acute dermis capillary rupture, secondary to noninvasive blood pressure (NIBP) monitoring in a patient with type 2 diabetes mellitus (DM) and hypertension. The first most likely cause is vascular fragility in microangiopathy as a result of DM and chronic steroid use. The second is the increased venous pressure during cycling of the blood press...

Rumpel-Leede phenomenon presenting as a hypertensive urgency.

Rumpel-Leede (R-L) phenomenon is the rare event in which the small dermal capillaries of an extremity rupture in response to application of a compressive device to that extremity, such as when inflating a cuff during noninvasive blood pressure monitoring or when applying a tourniquet to draw blood. This capillary rupture results in formation of a petechial rash distal to the compressive device....

University of Veterinary Medicine Morphological and functional integration and survival of intrastriatal dopamine grafts in a rat model of Parkinson’s disease

The semicolon sign: dopamine transporter imaging artifact from head tilt.

Dopamine transporter (DAT) imaging is a valuable tool to aid in the diagnosis of Parkinson disease and other Parkinsonian syndromes. DAT imaging is special among clinical nuclear medicine scans in that the already small caudate and putamen are presented in multiple thin axial cuts. Because the imaged basal ganglia are small, slight differences in head tilt may result in a significant artifact t...
