We report diffusion-weighted magnetic resonance imagings (DWI) at the acute stage of two patients with spectacular shrinking deficit (SSD) due to cardioembolic stroke. Patient 1 was a 74-year-old woman with atrial fibrillation (Af) who had been admitted for acute cholecystitis. She abruptly developed consciousness disturbance, global aphasia and right hemiparesis. Her neurological symptoms rapidly improved 30 minutes after onset, and completely disappeared in four hours. Patient 2 was a 84-year-old woman with Af who had been on medication of warfarin potassium for three years. She abruptly developed consciousness disturbance and left hemiplegia. Her neurological symptoms rapidly improved 90 minutes after onset, and almost completely disappeared in ten hours. Their conditions were consistent with SSD in acute cardioembolic stroke. DWI of Patient 1 taken 27 hours after onset showed hyperintense signal areas in the insular and temporal cortices of the left middle cerebral artery territory, and in the parietal cortex corresponding to the border zone between the territories of the left middle cerebral artery and posterior cerebral artery. DWI of Patient 2 taken 39 hours after onset showed hyperintense signal areas in the insular and frontal cortices of the right middle cerebral artery territory, and in the parietal cortex corresponding to the border zone between the territories of the right middle cerebral artery and posterior cerebral artery. They indicated multifocal ischemic injuries at the acute stage. The T2-weighted MRI of Patient 2 showed a slight hyperintense signal area only in the right parietal cortex, but the fluid-attenuated inversion recovery (FLAIR) in both patients showed no abnormal signals in the corresponding areas. To our knowledge, ischemic lesions in DWI of SSD at the acute stage after rapid recovery have not been reported previously. DWI is useful in SSD for detecting ischemic injuries of cardioembolic origin at the early stage.

Portal pneumatosis is a rare diagnostic factor, which is often associated with ischemic intestinal accidents. It has been associated with a negative prognosis for a very long time, and the presence of portal pneumatosis is usually an indication for the need to perform a laparotomy. A 68-year-old male patient with diabetes, obstructive lung disease, and a previous cerebral stroke associated with left hemiplegia presented with abdominal pain, fever and neutrophil leukocytosis. Computed tomography (CT) scan showed the presence of portal pneumatosis with signs of acute cholecystitis and remarkable gastrectasia. In consideration of the serious clinical picture, the patient first underwent esophagogastroduodenal endoscopy (EGDS), which showed ulcerative hemorrhagic gastritis. He then underwent a laparoscopic cholecystectomy. The histology results confirmed the intraoperative diagnosis of gangrenous cholecystitis. The patient was discharged on the 7th postoperative day. With the use of new diagnostic techniques, especially CT, the incidence of portal pneumatosis has increased and consequently the clinical approach of surgeons to this pathology is also changing. Indeed, when portal pneumatosis is not associated with intestinal ischemia, the therapeutic approach must be guided by the clinical condition of the patient and by the investigation of the causes of this pathology. The laparoscopic approach can be extremely useful either in the diagnosis (if this has not been achieved by noninvasive means) or in treatment, if possible, of the causes implicated by the portal pneumatosis.
