The diagnosis of pulmonary hypertension in non-Hodgkin's lymphoma confers a relatively poor prognosis, emphasizing the critical need for early recognition and tailored management strategies. Standard pulmonary hypertension treatments may yield suboptimal responses due to the underlying neoplastic origin, highlighting the importance of prompt initiation of chemotherapy. We present a unique case of pulmonary hypertension in marginal zone lymphoma along with a comprehensive review of reported non-Hodgkin's lymphoma cases associated with pulmonary hypertension, shedding light on the diagnostic and therapeutic challenges encountered in clinical practice.

Elevation of pressure within tightly bound myofascial compartments has detrimental consequences if not treated promptly, leading to a loss of circulation, ischemia, myonecrosis, nerve damage, and limb loss. They are commonly seen in the distal upper and lower extremities; however, compartment syndrome of the hand is rarely encountered and prompt recognition can prevent permanent damage and tissue loss. This case study presents a complicated case of compartment syndrome of the hand and discusses the interrelationship between compartment syndrome and rhabdomyolysis. An emphasis is placed on pathophysiology of this relationship to allow a better understanding of the imaging features as well as early clinical recognition of compartment syndrome. Magnetic resonance imaging findings are specifically discussed as it remains the best imaging tool to evaluate the extent of the damage and surgical planning.

Fat embolism occurs in the vast majority of patients who have had trauma (approximately 90%). The most common occurrence is after long bone fracture. It has also been noted in cases after orthopedic surgery. Fat embolism is most often diagnosed when the clinical manifestations of fat embolism syndrome become apparent. Reported cases of fat emboli in transit are unusual. In our case, we present the rare finding of fat embolism seen on computed tomography in the lower extremity after a trauma.
