Bedside Ultrasound of Retinal Detachment in a 19-year-old

Rami San Gabriel, BS*, Maili Alvarado, MD* and Vy Han, MD*

DOI: https://doi.org/10.21980/J80W6TIssue 3:3[mrp_rating_result]
The ocular point of care ultrasound (POCUS) utilizing a high frequency linear probe shows a retinal detachment (RD) with a thick, hyperechoic undulating membrane in the vitreous humor that is anchored at the ora serrata anteriorly and the optic disc posteriorly. Note that the retina is detached all the way to the optic disc making it "mac off." The macula, and more specifically the fovea, is located in the central retina and contains a high concentration of cone photoreceptors responsible for central, high resolution, color vision. In a "mac on" RD, the retina detaches in the periphery but remains intact centrally. This is an ophthalmologic emergency and timely diagnosis and intervention can be vision saving. This patient also has evidence of a posterior vitreous hemorrhage which has a characteristic swirling appearance with kinetic exam on real-time imaging. The detached vitreous body is not as well defined and is not anchored posteriorly to the optic disc.

The Role of Chest X-Ray and Bedside Ultrasound in Diagnosing Pulmonary Bleb versus Pneumothorax

Mohamad Moussa, MD* and Venkat Reddy Vaddamani, BS*

DOI: https://doi.org/10.21980/J8MP7QIssue 3:3[mrp_rating_result]
The patient was evaluated with bedside ultrasound for concern of possible pneumothorax. Imaging of the left lung with M-mode demonstrated a “sea shore” sign showing a wavy pattern below the pleural line caused by lung sliding as well as “comet tail” artifact caused by from the deep pleura. However, there was no lung sliding on the right shown by a lack of “comet tail” artifact and a “bar code” sign where M-mode shows straight lines throughout the image, this is caused by lack of motion below the pleura. This lack of lung sliding is consistent with possible pneumothorax or bleb.  A two-view chest X-ray (CXR) revealed absent lung parenchyma in the right lung similar to a large pneumothorax (see red outline). Electronic medical record chart review revealed previous CXRs with similar findings. This patient was determined to have an acute COPD exacerbation with chronic blebs, but no pneumothorax.

The video shows a water bath ultrasound of the right 4th digit, demonstrating soft tissue swelling with a hypoechoic region along the tendon consistent with edema and tendon disruption (see video and annotated still image).

A Rare Cause of Pelvic Pain in a Teenage Girl

Amber Marie Hathcock, MD, MPH*, Manish I Shah, MD, MS*, Jennifer E Dietrich, MD, MSc^ and Esther M Sampayo, MD, MPH*

DOI: https://doi.org/10.21980/J87D0WIssue 3:3[mrp_rating_result]
Due to pain out of proportion to her exam, an ultrasound of her pelvis was obtained and showed a blood-filled distended uterus, or hematometrocolpos (white arrow), with a 4.9 cm right ovarian cyst (blue arrow). A pelvic magnetic resonance imaging (MRI) then revealed an obstructed right hemi-vagina, normal left uterus and vagina and ipsilateral renal agenesis (red arrow) with normal left kidney (double arrow) consistent with obstructed hemivagina, ipsilateral renal agenesis (OHVIRA) syndrome. The patient underwent surgical repair with complete resolution of symptoms.

Right Ventricular Dilation in Patient With Submassive Pulmonary Embolism

Adrian Diez, MD* and Christopher Bryczkowski, MD*

DOI: https://doi.org/10.21980/J82P84Issue 3:3[mrp_rating_result]
Bedside echocardiography four chamber view revealed enlarged right ventricular (RV) to left ventricular (LV) ratio (greater than 1) on apical four-chamber view (see red and blue outlines respectively). The right atrium is not clearly delineated in this image and therefore is not outlined. One can also rule out a large pericardial effusion as the cause of her dyspnea, since there is no large hypoechoic collection surrounding the heart on either four- chamber view or parasternal long view.

Point of Care Ultrasound Illustrating Small Bowel Obstruction

Badriah Alruwaili, MBBS* and Shadi Lahham, MD*

DOI: https://doi.org/10.21980/J8T637Issue 3:3[mrp_rating_result]
POCUS of the small bowel illustrated significantly dilated loops of bowel (white line), thickened bowel wall (white arrow) and to-and-fro peristalsis, consistent with small bowel obstruction.

Retinal Detachment

Adnan Riaz, MD*, Chirag Shah, MD* and Grant Wei, MD*

DOI: https://doi.org/10.21980/J8204QIssue 3:2[mrp_rating_result]
Bedside ocular ultrasound revealed a serpentine, hyperechoic membrane that appeared tethered to the optic disc posteriorly with hyperechoic material underneath. These findings are consistent with retinal detachment (RD) and associated retinal hemorrhage.

Intussusception

DOI: https://doi.org/10.21980/J8SH0WIssue 3:2[mrp_rating_result]
A segment of bowel within the right abdomen that measured approximately 1.6 x 1.5 cm transaxially. It demonstrated a hypoechoic edematous outer loop of bowel (blue arrow) and hyperechoic compressed loop of bowel telescoping within (red star), this is known as the "target sign."
