Parasitic infestations of the ovary are quite rare with ovary being the least common site of infection in the female genital tract. Filariasis is a parasitic disease caused by filarial nematodes (Wuchereria bancrofti, Brugia malayai, Brugia timori). It causes lymphatic obstruction with resultant edema and increase in the size of the affected organ. We report a case of 24-year-old married female who presented to our radiology department for ultrasound evaluation with the main aim being to look for retained products of conception after the termination of early pregnancy. However on ultrasound examination ovarian filariasis was an incidental diagnosis with the classical twirling movement (filarial dance sign) seen in one of the follicles of the ovary. Ultrasound is the imaging modality of choice for detecting the adult filarial worm/microfilaria in the lymphatic system. Ovarian filariasis is a very rare diagnosis with only a handful of cases being reported in literature with most cases being diagnosed incidentally on histopathological examination of the post operative specimen.

Facial nerve neuromas rarely occur in the intra-parotid segment of the facial nerve and when they do, masquerade as a parotid lump. The imaging and clinical features of the intra-parotid facial neuroma overlaps with the more commonly encountered salivary gland neoplasms and is thus overlooked. However, if not recognized, may result in serious and avoidable adverse events for the patient if biopsied or surgically removed. These include pain, facial nerve palsy and cosmetic deformity. In this report, we present the case of a 47-year-old male patient with an intra-parotid facial nerve neuroma with images including computer tomography, magnetic resonance imaging and intra-operative photos. The lesion was eventually left in situ to avoid facial nerve palsy and preserve cosmesis. A discussion of the imaging characteristics and differential diagnoses is subsequently elaborated.

Venous malformations are now categorised under the broad heading of slow flow vascular malformations. They comprise abnormally dilated venous channels that fail to involute. These may be superficial or deep in location. We describe two cases of venous malformation in breast. Both the patients presented with focal pain in one breast. On mammography, they appeared as equal density well circumscribed soft tissue masses. No sonographic correlate was found on initial ultrasound examination. Subsequent ultrasonography performed by an experienced radiologist with minimal probe pressure revealed dilated veins. On the basis of imaging findings, the diagnosis of venous malformation was established.

Our case is a 24-year-old woman who has had abdominal enlargement for eleven months. She had an abdominal mass with an elevated level of CA-125 and imaging studies showed a pelvic cystic mass with a solid part, and thus malignancy was considered in the differential diagnosis. A laparotomy myomectomy was performed. Postoperative histopathological examination results revealed no signs of malignancy. In this case, both ultrasonography and magnetic resonance imaging could not visualize both ovaries and the stalk of the pedunculated fibroid on the posterior uterine corpus. On physical examination and imaging, cystic degeneration of uterine fibroid may present like an ovarian mass. Preoperative diagnosis is challenging. A definitive diagnosis is only feasible postoperatively following histological examination.

Prevotella melanogenica is a typical organism present in the human oral cavity and female reproductive tract, which is responsible for causing periodontal disease and the inflammation of the female reproductive tract. The present report discusses the case of a young female patient who presented with cough and fever as the main clinical symptoms. Computed Tomography (CT) revealed multiple clusters of ground glass density shadows in both lungs, with network-like and paving stone-like changes. The alveolar lavage fluid was collected for next-generation sequencing, which revealed the presence of Prevotella melanogenica. The patient received treatments, CT revealed that the density of multiple flakes of ground glass density in both lungs was lower than the previously observed density. Prevotella melanogenica pneumonia is rare, and the paving stone symptom observed in CT is not specific. Therefore, the case reported here provides a novel perspective regarding the diagnosis of pneumonia.

Background: A 36-year-old man presented with a palpable mass in the right axillary tail for four months. He was referred to breast imaging for diagnostic work-up. He does not have a family history of breast cancer.

Aim: Breast imaging work-up for diagnosis of lymphoma is unusual and even more so in a male patient.

Case presentation: After Breast Mammography and targeted Ultrasound of the axillary tail and axilla, Magnetic Resonance Imaging (MRI) was performed and suggested lymphoproliferative disorder. Excisional biopsy was performed after the breast MRI with removal of right axillary tissue measuring 15.0 × 5.5 × 2.0 cm and containing multiple lymph nodes. Excisional biopsy revealed Classic Hodgkin lymphoma of nodular sclerosis type. Staging [18F]-FDG PET/CT revealed early stage of disease.

Conclusion: The presentation and diagnostic elements of Hodgkin Lymphoma are described in this case report emphasizing the significance of breast imaging in multiple populations.

We report a case of a solid pseudopapillary epithelial neoplasm of the pancreas in a 19-year-old female who presented with abdominal pain. Computed tomography of the abdomen showed a heterogenous density mass in the tail of the pancreas. The mass had fluid density in the central region and soft tissue density in the peripheral region. Post-contrast evaluation showed enhancement in the peripheral solid component. Based on the radiological investigation carried out at our institute, a diagnosis of solid pseudopapillary epithelial neoplasm of the pancreas was established which was confirmed on histopathology.

Background: Diffuse idiopathic skeletal hyperostosis and spondyloarthritis share similarities in clinical and radiological findings. In this article, we report a case of overlapping of these two hyperostotic diseases followed by an extensive narrative review of the literature focusing on the gray areas in the diagnosis of diffuse idiopathic skeletal hyperostosis.

Case description: We report the case of simultaneous diffuse idiopathic skeletal hyperostosis and ankylosing spondylitis in a 57-year-old man. The diagnosis was made after many collegial meetings based on solid radiological arguments.

Conclusion: Review of the literature reveals many uncertainties in the diagnosis of diffuse idiopathic skeletal hyperostosis, especially in the radiological evaluation of sacroiliac joints. Diffuse idiopathic skeletal hyperostosis and ankylosing spondylitis frequently overlap in important radiological features leading to diagnostic ambiguity and they can also co-exist in the same patient.

Spontaneous pneumomediastinum is characterized by the accumulation of air in the mediastinum with no identified cause. It is a rare and self-limiting condition. We report the case of a 32-year-old female patient with controlled bronchial asthma, who presented with spontaneous pneumomediastinum, with no precipitating event. The evolution is generally benign and the treatment is conservative. Symptomatic medication may be instituted.
