A case of post-HoLEP vasitis mimicking incarcerated inguinal hernia. A diagnostic approach.

Vasitis is inflammation of the vas deferens, which can be divided into acute inflammatory vasitis or chronic vasitis nodosa. Acute vasitis can present with inguinal pain, swelling, or a lump, which could mimic other common pathologies occurring at this site, particularly inguinal hernia. While ultrasound is effective in the diagnosis of epididymitis, orchitis, and hernia, this case illustrates the importance of cross-sectional imaging to establish the correct diagnosis of vasitis, to aid in the prevention of unnecessary surgical exploration and to expedite antibiotic treatment. Previous surgical intervention to the prostate is the leading risk factor for vasitis and should be taken into consideration when making a differential diagnosis and determining which image modality to use. Here, we present a case of vasitis in a 60-year-old male with previous Holmium laser enucleation of the prostate (HoLEP), with an initial diagnosis of inguinal hernia on ultrasound which was later diagnosed as acute vasitis on CT.

Juxta-articular extraskeletal myxoid chondrosarcoma mistaken for a benign cyst presenting with multiple lung metastases.

Extraskeletal myxoid chondrosarcoma (EMC) is a malignant cartilage neoplasm usually encountered in the proximal extremities. We report the case of a 58-year-old male who presented initially with a 3-month history of cough. Initial staging demonstrated a right upper lobe mass with bilateral pulmonary nodules and moderate tracer uptake in the right lung mass and right groin on positron emission tomography imaging. Endobronchial ultrasound biopsy confirmed a histological diagnosis of EMC for which the patient underwent right upper lobe wedge resection. Pelvic MRI revealed a peripherally enhancing juxta-articular lesion within the region of the right obturator externus bursa, which was thought initially to represent either a ganglion or paralabral cyst. However, ultrasound-guided biopsy yielded identical histology to the resected lung mass leading to the diagnosis of primary EMC in the right groin with pulmonary metastases. The patient underwent surgical excision of the right groin mass with no local recurrence on the surveillance computed tomography at 5, 12, and 18 months but eventual disease recurrence in the right groin and further progression of the pulmonary metastases at 29 months. We emphasize that the contrast enhancement pattern of EMC can mimic a benign cystic lesion, in particular, when in a juxta-articular location, which has the potential to mislead radiologists and delay diagnosis and definitive treatment.

A case of cerebral venous sinus thrombosis presented with SAH and isolated headache.

Cerebral venous sinus thrombosis is a rare and challenging type of stroke. Coexistence of subarachnoid hemorrhage adds complexity to the diagnostic process leading to a missed or delayed diagnosis. Isolated headaches can be the only presentation and urgent neuroimaging using CT or MR venogram plays a pivotal role in the workup of these cases. We report a rare case of 64-years-old patient with subarachnoid hemorrhage and underlying cerebral venous sinus thrombosis who was presented with isolated headache where the management is different from arterial subarachnoid hemorrhage.
